Phpmyadmin Filezilla

admin

Nov 09, 2013 You wouldn't use Filezilla to transfer files to a mySQL database as the two don't really work together. Filezilla is for moving files to/from a file server but database servers don't really work this way. Once you have the Joomla files on your file server, you would just visit the URL for the website and enter the database credentials there.

  1. Hiiiii everybody I'm Ayush Rajgor. It is the 7th video of the AWS series. In this video, i will show you how to access wordpress database in aws.
  2. Use Filezilla or similar software. Make sure your domain is pointing to /public folder. Depending on where the domain is managed – it will be some kind of Plesk, DirectAdmin or similar software on the client’s server panel. Database: export/import with phpMyAdmin.

Introduction

LAMP/WAMP/MAMP Server

To develop PHP webapps, you need to setup Apache + MySQL + PHP under your operating system, in a so called LAMP (Linux-Apache-MySQL-PHP), WAMP (Windows-Apache-MySQL-PHP), or MAMP (macOS-Apache-MySQL-PHP) environment.

There are two ways of setting up LAMP/WAMP/MAMP:

  1. Install individual software components, i.e., (a) Apache, (b) MySQL, (c) PHP, and (d) Other utilities.
  2. Install a bundle package, which includes all software components (a) to (d) needed for developing PHP webapps.

For beginners running on Windows/macOS, I certainly recommend the bundle approach for simplicity (although they might not bundled the latest releases). These are the bundles available:

  • XAMPP @ https://www.apachefriends.org/index.html (Cross-platform for Windows, macOS and Linux).
  • WampServer @ http://www.wampserver.com/en/ (for Windows only).
  • Zend Server (@ http://files.zend.com/help/Zend-Server-Community-Edition/zend-server-community-edition.htm) (Cross-platform for Windows, macOS and Linux).
  • Easy PHP (@ http://www.easyphp.org/).
  • Others.

I shall describe how to install and setup some of these bundles in the next section.

Integrated Development Environment (IDE) and Debugger
Phpmyadmin Filezilla

You also need to install an IDE, such as Eclipse PHP Development Tool (PDT) (read 'How to install Eclipse PDT'), NetBeans, IntelliJ IDEA, or others.

You need to setup these debugging tools and be familiar with:

  • Server-side PHP debugging with 'xDebug' or 'Zend Debugger', and
  • Client-side JavaScript debugging using the so-called 'F12 debugger' under 'Developer Tools' (which deprecated the famous 'Firebug').

Read Section 'Debugging PHP Webapps'.

Programming Languages

I shall assume that you have some basic knowledge on these programming languages. Otherwise, read the relevant sections.

  1. Database programming: SQL (on MySQL or PostgreSQL). Read the 'SQL Section'.
  2. Sever-side programming: PHP (or Python, or Perl). Read 'PHP Section'
  3. Client-side programming: HTML, CSS and JavaScript. Read 'Client-side Programming: HTML/CSS/JavaScript Section'. For advanced client-side programming: BootStrap, jQuery, Augular.js, React.js.
Version Control System (Git)

Set up a Version Control System, such as Git (on Github), for backup, version control and collaboration. Read 'How to setup and get started with Git'.

LAMP/WAMP/MAMP Servers

In this section, I shall briefly describe how to install and customize some of the AMP bundles. To install individual components, read 'How to install and get start with Apache', 'How to install and get started with MySQL'.

XAMPP (For Windows/macOS/Linux)

The XAMPP (@ https://www.apachefriends.org/index.html) stands for Cross-platform (X), Apache (A), MariaDB (formerly MySQL) (M), PHP (P) and Perl (P). It bundles the free and open-source Apache, MariaDB/MySQL, PHP and Perl, for Windows, Linux and macOS. It also includes PhpMyAdmin, FileZilla FTP Server, Mercury Mail Server, Tomcat Server; Webalizer and Fake Sendmail.

At the time of writing (Apr 2021), XAMPP 8.0.3 bundles PHP 8.0.3, Apache 2.4.6, MariaDB 10.4.18 and PhpMyAdmin 5.1.0. See 'Wiki XAMPP'.

Installing XAMPP on Windows
  1. Download: Goto XAMPP mother site at https://www.apachefriends.org/index.html ⇒ Download the Windows package (e.g., xampp-windows-x64-8.0.3-0-VS16-installer.exe).
  2. Install: Simply run the downloaded Installer. Choose your installation directory. I shall assume that XAMPP is installed in 'c:xampp', denoted as <XAMPP_HOME>, in this article.
Installing XAMPP on macOS [@@To Check!!]

Phpmyadmin Filezilla Download

  1. Download: Goto XAMPP mother site at https://www.apachefriends.org/index.html ⇒ Download the macOS package (e.g., .....).
  2. Install: Simply run the downloaded Installer. Choose your installation directory. I shall assume that XAMPP is installed in '......', denoted as <XAMPP_HOME>, in this article.
Starting/Stopping XAMPP Servers

Launch the 'XAMPP Control Panel' ('xampp-control.exe' for Windows, @@To Check ...... for macOS) under the XAMPP installed directory. A little icon appears in the Icon Tray. Right-click on the icon ⇒ 'Show/Hide' to show the 'full' Control Panel Window.

The 'XAMPP Control Panel' allows you to start/stop each of these servers: Apache HTTP Server, MySQL Database Server, FileZilla FTP Server, Mercury Mail Server, and Tomcat HTTP Server. You can also check their configurations ('Config'), logs ('Logs') and launch the administrator tools such as PhpMyAdmin for MySQL ('Admin').

Verifying the Apache/MariaDB Servers Installation

By default, a directory called 'htdocs' was created under the XAMPP installed directory, which serves as the Apache's document root directory.

To verify the installation, launch the 'XAMPP Control Panel'. Start the Apache and MariaDB/MySQL servers by clicking the 'Start' buttons.

  • On your browser, issue 'http://localhost' (or 'https://localhost'). Check out the menu items such as 'HOW-TO Guides', 'FAQs', 'PHPInfo'.
  • Check out the 'htdocs' (Apache's document base directory) and browse thru the 'index.php'.
  • Select 'phpMyAdmin' from the dashboard, or issue 'http://localhost/phpmyadmin', or click the 'Admin' button under MySQL to launch PhpMyAdmin webapp to access the MariaDB/MySQL. Select the 'User accounts' tab, which reveals that no password is set for the superuser root and the anonymous user 'Any'. Set a password for root, and remove the anonymous user (See 'PhpMyAdmin' section).

To shutdown XAMPP, stop all the services (servers) and press 'Quit'.

Write a Hello-world PHP Script

By default, the Apache's document root directory is located at '<XAMPP_HOME>/htdocs'. Use a programming editor (such as notepad++ for Windows, or gedit for Ubuntu/macOS) to write a simple PHP script called 'hello.php' and save under the 'htdocs' directory, as follows:

To run this PHP script, start a browser and issue URL http://localhost/hello.php, assuming that Apache server has been started.

Example 'phpinfo': Write another PHP script called 'RunPhpinfo.php' (saved under 'htdocs') to display the PHP settings under Apache, as follows:

Run the script by issuing URL 'http://localhost/phpinfo.php'. The PHP's built-in function phpinfo() outputs a fully-formatted HTML page showing the details of your PHP environment.

XAMPP Directory Structure

XAMPP is organized in the sub-directories. The important ones are:

  • htdocs: the default apache's document root directory.
  • apache, mysql, FileZillaFTP, MercuryMail, tomcat: for the server software.
  • phpMyAdmin: for the PhpMyAdmin tool.
  • php, perl: for the languages.
Apache Configuration

The Apache's main configuration file 'httpd.conf' is located at '<XAMPP_HOME>apacheconf'. Take note of the following configuration directives:

  • The core directives are: The ServerRoot specifies the apache's installed directory. Listen specifies the TCP port number for Apache web server, in this case, default of TCP port 80. The DocumentRoot specifies the root directory of the web server.
  • The directives related to directory authorization are (for Apache 2.4, not compatible with Apache 2.2): [TODO] Explanation
  • The directives related to logging are:
PHP Configuration

The PHP's main configuration file 'php.ini' is located from '<XAMPP_HOME>php' (as revealed by phpinfo() output).

[TODO] Explanation

MySQL Configuration

The MySQL's main configuration file 'my.ini' is located at '<XAMPP_HOME>mysqlbin'. Take note of the following settings:

  • MySQL Server Daemon (mysqld.exe) The port specifies the TCP port number for the MySQL server (defaulted to 3306). The basedir specifies the MySQL installed directory. The datadir specifies the databases directory. The log-error specifies the MySQL error log file.
  • MySQL Interactive Client (mysql)
Customizing MySQL

The default MySQL installation creates a superuser called 'root' without password. It also provides an anonymous user with no password. You need to:

  1. Set a password for 'root'.
  2. Remove the anonymous user.
  3. You should not use superuser 'root' for normal daily operations. Instead, create a new user (says xampppuser) for operational use.

You can administrate MySQL via PhpMyAdmin. See the 'PhpMyAdmin' section.

Start a new PHP Webapp

To start a new PHP webapp, create you working directory under 'htdocs' (says directory 'hello'). You can launch your webapp via URL 'http://localhost/hello'. Alternatively, you can use the 'htdocs' directory, by removing all the existing contents. You can access the webapp via URL 'http://localhost'.

For Production, configure a virtual host (in Apache) for your project.

WampServer (For Windows)

[TODO] Outdated! Need to Update. The cross-platform XAMPP (in the previous section) recommended.

WampServer (@ http://www.wampserver.com/en/) bundles Apache, MySQL and PHP for Winodws in a single package. It also includes tools such as PhpMyAdmin (a MySQL database administration tool), SQL Buddy (an alternative to PhpMyAdmin), XDebug (a PHP Debugging Tool), WebGrind (a PHP Profiling Tool).

At the time of writing (Sept 2014), WampServer 2.5 bundles Apache 2.4.9, MySQL 5.6.17, PHP 5.5.12, PhpMyAdmin 4.1.14, SqlBuddy 1.3.3 and XDbebug 2.2.5.

Installing WampServer

To Install WampServer:

  1. Download: Goto WampServer mother site at http://www.wampserver.com/en ⇒ Select 'DOWNLOADS' ⇒ Choose the appropriate package for your platform (32-bit or 64-bit) ⇒ Download the installation file (e.g., wampserver2.5-Apache-2.4.9-Mysql-5.6.17-php5.5.12-64b.exe).
  2. Install: To install the WampServer, simply run the downloaded installation file. Choose your installation directory. I shall assume that WampServer is installed in 'd:WampServer', denoted as <WAMPSERVER_HOME>, in this article.
Starting/Stopping WampServer

To start the WampServer, choose 'Start WampServer' from the 'Start' menu; or run 'wampmanager.exe' from the WampServer installed directory.

An little icon will appear on the icon tray. 'Green' indicates that all the services have started; while 'Red' indicates that all the services have stopped. Click on the icon to open the 'WampServer Control Panel'. You could:

  • Under 'Quick Admin': Start/Stop/Restart all the services (Apache & MySQL services).
  • Put the server online (so that user can access the server over the Internet) or offline.
  • Configure Apache, MySQL and PHP, under their respective sections.
  • Launch 'PhpMyAdmin'.
  • Others.

To shutdown the program, click 'Stop All Services' on WampServer Control Panel ⇒ right-click on the WampServer icon ⇒ Exit.

Verifying Apache/MySQL/PHP Installation

By default, a directory called 'www' was created under the WampServer installed directory, which serves as the Apache's document root directory. A welcome page called 'index.php' was also created in the 'www' directory.

To verify the installation:

  1. Start the WampServer. Wait for the icon to turn green indicating all services have started (otherwise, click the icon and select 'Start All Services'). For testing, put the server 'offline' to disable external access (i.e., it can only be accessed in localhost).
  2. To verify Apache: Start a browser and issue URL http://localhost. This will in turn request for 'index.php'. The index page provides links to documentations, aliases and tools. The installation creates these aliases for Apache: phpmyadmin, sqlbuddy, phpsysinfo for the respective services. You can issue URL http://localhost/alias-name to access these services.
  3. To verify MySQL: Issue URL http://localhost/phpmyadmin to access the MySQL via PhpMyAdmin. Click on the 'Users', which reveals that no password was set for the superuser root and the anonymous user.
  4. To verify PHP: Issue URL http://localhost/?phpinfo=1, which runs the phpinfo() function.
Write a Hello-world PHP Script

Use a programming editor (such as notepad++ for Windows, or gedit for Ubuntu/macOS) to write a simple PHP script called 'hello.php' and save under the 'www' directory, as follows:

To run this script, start a browser and issue URL http://localhost/hello.php, assuming that the Apache server has been started.

Another Example: Write another PHP script called 'phpinfo.php' (saved under 'www') to display the PHP settings under Apache, as follows:

Run the script by issuing URL 'http://localhost/phpinfo.php'.

WampServer Directory Structure

WampServer is organized in the following directory structure. The important ones are:

  • bin: contains binaries for Apache, MySQL, and PHP, in their respectively sub-directory. For each component, you can install multiple versions and select one of them in operation.
  • apps: contains server-side tools such as PhpMyAdmin, SQL Buddy, and WebGrind.
  • tools: contains client-side tool such as xdc (XDebug Client).
  • www: the default apache's document root directory.
  • logs: contains apache, php, mysql error/access logs.
  • alias: contains the the apache's alias configuration for PhpMyadmin, SQL Buddy and WebGrind.

Apache Configuration

The Apache's main configuration file 'httpd.conf' is located at '<WAMPSERVER_HOME>binapacheApache2.x.xxconf'. Take note of the following configuration directives.

  • The core directives are: The ServerRoot specifies the apache's installed directory. Listen specifies the TCP port number for Apache web server, in this case, default of TCP port 80. The DocumentRoot specifies the root directory of the web server.
  • The directives related to directory authorization are (@@ For Apache 2.2 only, need to update for Apache 2.4): [TODO] Explanation
  • The directives related to logging are:
PHP Configuration

The PHP's main configuration for Apache2 'php.ini' is located at '<WAMPSERVER_HOME>binapacheApache2.x.xxbin' (as revealed by phpinfo() output).

[TODO] Explanation

MySQL Configuration

The MySQL's main configuration file 'my.ini' is located at '<WAMPSERVER_HOME>binmysqlmysql5.x.xx'. Take note of the following settings:

  • MySQL Server The port specifies the TCP port number for the MySQL server (defaulted to 3306). The basedir specifies the MySQL installed directory. The datadir specifies the databases directory. The log-error specifies the MySQL error log file.
  • MySQL Server Daemon (mysqld.exe)
  • MySQL Interactive Client (mysql)

PhpMyAdmin - PHP Apache Webapp for MySQL Administration

PhpMyAdmin (http://www.phpmyadmin.net) is a popular open-source PHP webapp tool for administrating and manipulating MySQL/MariaDB database system.

Installing PhpMyAdmin

PhpMyAdmin a PHP webapp which runs under the Apache Server. Hence, it is bundled with a AMP (Apache-MySQL/MariaDB-PHP) distribution, such as XAMPP.

Launching PhpMyAdmin

PhpMyAdmin is an Apache PHP webapp. Typically, an alias called 'phpmyadmin' is defined which maps to its installed directory.

To launch PhpMyAdmin, start Apache and MySQL servers. Then, start a browser and issue URL http://localhost/phpmyadmin.

Setting or Changing MySQL/MariaDB root's Password

After the installation, MySQL/MariaDB's superuser root has no password or has a randomly-generated password. We need to set/change the root's password immediately after installtion.

Step 1: Change MySQL/MariaDB root's Password

There are a few ways to set/change root's password:

  • Using PhpMyAdmin: Launch PhpMyAdmin ⇒ Select 'User accounts' from the top menu ⇒ Click on 'Edit privileges' under '[email protected]' ⇒ You will find an option 'Change password' on the top menu ⇒ Enter the new password.
  • Using command-line mysql client:
Step 2: Modify the PhpMyAdmin's config 'phpMyAdminconfig.inc.php'

PhpMyAdmin does not maintain its own users, but uses MySQL/MariaDB users to login to the MySQL/MariaDB.

The initial configuration in 'phpMyAdminconfig.inc.php' is as follows:

The 'auth-type' of 'config' instructs the PhpMyAdmin to get the user/password from this config file, without showing a login screen (i.e., hardcode the user/password in config). Hence, you need to provide the root's new password once it is set/changed.

A better approach is to change the 'auth-type' to 'cookie'. A login screen will be shown and the user/password will be captured from the login screen. You can use any valid MySQL/MariaDB users to login. The config is as follows:

Creating New User

To create a new user say xamppuser:

  • Using PhpMyAdmin: Launch PhpMyAdmin ⇒ Select 'User accounts' from the top menu ⇒ Click 'Add user account' ⇒ Fill in the information.
  • Using command-line mysql client:

Using PhpMyAdmin

[TODO]

PhpMyAdmin's Configuration for Apache

  • In XAMPP: PhpMyAdmin is configured in '<XAMPP_HOME>apacheconfextrahttpd-xampp.conf', which is included into Apache's main configuration file '<XAMPP_HOME>apacheconfhttpd.conf' via an Include directive. In the configuration, an alias called '/phpmyadmin' is defined which maps to PhpMyAdmin's directory at '<XAMPP_HOME>/phpMyAdmin/'.
  • In WampServer: PhpMyAdmin is configured in '<WAMPSERVER_HOME>aliasphpmyadmin.conf', which is included into Apache's main configuration file '<WAMPSERVER_HOME>binapacheapache2.4.9confhttpd.conf' via directive 'Include '<WAMPSERVER_HOME>/alias/*''. In the 'phpmyadmin.conf', an alias called '/phpmyadmin' is defined which maps to PhpMyAdmin's directory '<WAMPSERVER_HOME>/apps/phpmyadmin4.x.xx/'.

Notes on Errors

  • Cannot login using root, after setting password. See above.
  • Error '#1034 index for table 'db' is corrupt': From PhpMyAdmin or mysql command-line client, issue this command:

Eclipse PDT (PHP Developer Tool)

Eclipse PDT (@ https://www.eclipse.org/pdt) is an IDE for PHP webapp development. The main advantage is it can debug PHP server-side scripts with XDebug or Zend Debugger extension.

Alternative PHP IDEs are: NetBeans (@ http://www.netbeans.org), PHPEclipse (@ http://www.phpeclipse.com).

Install Eclipse PDT

If you have never installed any Eclipse packages, goto Eclipse mother site @ http://www.eclipse.org ⇒ Downloads ⇒ Select 'Eclipse for PHP Developers':

  • For Windows: Download the ZIP file. Unzip the downloaded file in a directory of your choice.
  • For macOS: Read 'How to Install Eclipse on macOS'.
  • For Ubuntu: Read 'How to Install Eclipse on Ubuntu'.

If you have installed an Eclipse package (such as Eclipse IDE for Java Developers), you can add the PDT plugin by:

  1. Launched Eclipse ⇒ Select 'Help' menu ⇒ 'Install New Software'.
  2. In 'Work with' ⇒ Enter 'https://download.eclipse.org/tools/pdt/updates/latest/' ⇒ Add.
  3. In the 'Name' box ⇒ Check 'PHP Development Tools' ⇒ Next ⇒ Accept the license ⇒ Finish.
Writing a Hello-world PHP Webapp in Eclipse PDT
  1. Create a directory called 'hello' under your web server's root directory (or document base directory) for the hello-world PHP webapp (e.g., '<XAMPP_HOME>htdocshello' for XAMPP, '<WAMPSERVER_HOME>wwwhello' for WampServer).
  2. Launch Eclipse (with PDT). Choose a workspace.
  3. On Eclipse, create a new PHP project: 'File' ⇒ New ⇒ Project... ⇒ PHP ⇒ PHP Project.
    • In 'Project Name', enter a name for the project, e.g., 'helloPHP'.
    • In 'Contents', select 'Create project at exiting location' ⇒ 'Browse' to select the hello-world PHP webapp's base directory created in Step 1 (e.g., '<XAMPP_HOME>htdocshello' for XAMPP, '<WAMPSERVER_HOME>wwwhello' for WampServer) ⇒ Finish.
  4. Write your PHP script: Right-click on the project 'helloPHP' ⇒ 'New' ⇒ 'PHP File'. Enter the following codes and saved as 'HelloClass.php':

    Then, create a new PHP file for the following test driver 'HelloTest.php':

  5. To run the webapp, right-click anywhere on 'HelloTest.php' ⇒ Run As ⇒ PHP Web Application ⇒ Change the URL to http://localhost/hello/HelloTest.php.
    To select your browser, select 'Window' ⇒ Preferences ⇒ General ⇒ Web Browser ⇒ Choose your browser, such as internal web browser, or external web browser (Firefox, IE, etc).
  6. You can also run this script as a 'PHP CLI Application', i.e., a standalone Command-Line Interface program instead of server-side webapp, as the above program are purely PHP, with no HTML statements. Right-click on 'HelloTest.php' ⇒ Run As ⇒ PHP CLI Application.
    Eclipse will ask you to configure a 'PHP Executable' (under 'Window' ⇒ PHP ⇒ Installed PHPs) ⇒ Add ⇒Provide a PHP exeutable (e.g., for XAMPP-Windows, <XAMPP_HOME>phpphp.exe).
    Run again ⇒ The output will be shown in the eclipse's console.

Eclipse PDT Debugging Example 1: Debugging PHP Server-side Scripts

Let's trace through the 'helloPHP' PHP Webapp created earlier (in 'Eclipse PDT' section), which contains two PHP scripts: 'HelloTest.php' and 'HelloClass.php'.

  1. Set a breakpoint at line 2 of 'HelloTest.php' by clicking on the left margin.
  2. Right-click on 'HelloTest.php' ⇒ Debug As ⇒ PHP Web Application.
  3. Switch to 'Debug' perspective.
  4. The program shall break at line 2 of 'HelloTest.php'. Click 'Step Into (F5)' or 'Step Over (F6)' to trace through the program. Inspect the variables and observe the output at the web browser.
  5. You need to terminate the debugging session by pushing the 'Terminate' button.

Take note that if you check 'Break at First Line' in the debug configuration, the program will pause at the first line of a PHP file. You need to push 'Resume' or 'Step Over'.

Eclipse PDT Debugging Example 2: Debugging PHP Webapp (HTML+PHP)

Create the following two files 'Query.php' and 'ProcessQuery.php', saved under Apache's document root directory.

Phpmyadmin Filezilla Command

Note: This code is meant for illustrating PHP webapp debugging. In practice, the two files are often merged into one.

To run the PHP webapp, right-click on 'Query.php' ⇒ Run As ⇒ PHP Web Application

To debug the PHP webapp:

  1. right-click on 'Query.php' ⇒ Debug As ⇒ PHP Web Application.
  2. Switch to 'Debug' perspective.
  3. Push 'Resume (F8)' button to run thru the HTML code.
  4. Switch to the browser. Enter something in the textfield and click 'submit'.
  5. Switch back to Eclipse, it now breaks at the first line of 'ProcessQuery.php'.
  6. Click 'Step Into (F5)' or 'Step Over (F6)' to trace through the program. Inspect the variables and observe the output at the web browser.
  7. You need to terminate the debugging session by pushing the 'Terminate' button.

Install Phpmyadmin Filezilla

Take note that if your program contains HTML and PHP, your need to switch between the web browser (to enter data) and eclipse (to push 'Resume' to run thru the HTML codes, or 'Step Over/Into' to execute the PHP codes). At times, the browser/eclipse icons on the taskbar brink to remind you to switch over.

Note: I actually intend to name 'Query.php' as 'Query.html', but the XDebug session does not seem to start on HTML (although you could tailor the 'Run configuration' to start running from an HTML file)?! Let me know if you have an answer. For the time being, name all files (may be only the starting page) '.php' even they contains only HTML. This is not really a problem.
