XAMPP is a software package that bundles in a single package PHP + Apache + MySQL + phpMyAdmin + some other tools for PHP Web development in Windows environment. Part I: Installing XAMPP and Configuring the Apache Server and MySQL Database This first part will show you how to install XAMPP, start the Apache server, and create your first MySQL DB. Now, you need to connect the Debugger (Xdebug), Apache Server and MySQL DB (XAMPP) to PhpStorm: 5. If you have started PhpStorm before, you need to either close your current project using File - Close Project option or simply skip this step and go to File - Default Settings. You should see this screen. Installing and Configuring XAMPP with PhpStorm IDE € XAMPP is a cross-platform package consisting of an Apache HTTP server, MySQL database, PHP interpreter, and Perl interpreter. The word 'XAMPP' is an acronym, where 'X' stands for 'cross', meaning 'cross-platform', and the other letters stand for the package components.

This section provides a handful selection of tutorials that will help you get started with PHP debugging in PhpStorm.

Quick Start

Before proceeding with any of the debugging scenarios, you need to choose a debugging engine and install it in your PHP environment. These tutorials will guide you through the installation process:

With the debugging engine installed, you can start debugging by following the zero-configuration debugging approach:

  1. Choose and install the browser extension suitable for your browser.

  2. On the PhpStorm toolbar, toggle to start listening for incoming PHP debug connections, or choose Run | Start Listening for PHP Debug Connections from the main menu.

  3. Set a breakpoint in your code. Breakpoints can be set in the PHP context inside PHP, HTML, TWIG, BLADE, and files of other types. Line breakpoints can be set only on executable lines, but not on comments, declarations, or empty lines. For details on getting started with Twig and Blade debugging, refer to Debug Twig templates and Debug Blade templates.

  4. Start the debugging session in the browser using the installed browser extension.

  5. During a debugging session, examine the program state: see variable values, evaluate expressions, step through the program, and so on.

See Zero-configuration debugging for the detailed step-by-step instructions, and Advanced debugging scenarios for more debugging scenarios.

Debugging a PHP web application

Depending on your environment, you can debug your PHP Web application locally or remotely.

Php docker xdebug phpstorm
Local debuggingRemote debugging
The debugging engine and PhpStorm are running on the same machine.The debugging engine is running on a remote environment (for example, a remote server or a virtual machine).
Follow the Zero-configuration debugging procedure.
  • If you can establish direct connection between your machine and the remote server, that is, no firewall, router or ISP is blocking the connection from your remote server to the specific port on the local machine, follow the Zero-configuration debugging procedure.

  • Otherwise, if direct connection cannot be established, follow the Remote debugging via SSH tunnel procedure.

To test direct connection, run the telnet host 9000 (for Xdebug) or the telnet host 10137 (for Zend Debugger) command on the remote server and ensure that connection is established. Here, host is the IP address of the local machine PhpStorm is running on.

To check for opened inbound ports, you can use canyouseeme.org or a similar service.

Debugging a PHP CLI script

Depending on your environment, you can debug your PHP CLI script locally or remotely.

Local debuggingRemote debugging
The debugging engine and PhpStorm are running on the same machine.The debugging engine is running on a remote environment (for example, a remote server or a virtual machine).
Follow the Debug a PHP CLI script procedure.
  1. Set up a remote PHP interpreter as described in Configure remote PHP interpreters.

  2. Follow the Debug a PHP CLI script procedure.

Besides running an entire application, you may want to run a PHPUnit or Behat test that covers a specific class, function or scenario, with the debugging engine attached. To learn how to do it, follow the Create a test configuration for a specific target procedure.

Troubleshooting

When using Xdebug or Zend Debugger with PhpStorm, some misconfiguration can prevent the debugger from working. In the Troubleshooting guide, you will find the description of some common issues and learn how to troubleshoot them.

Advanced debugging scenarios

The following topics will assist you in exploring the advanced debugging scenarios in PhpStorm:

Download Xdebug

  • Download the Xdebug extension compatible with your PHP version and install it as described in the installation guide.

    Xdebug 3 brings performance improvements, simplified configuration, and PHP 8 support. To learn more on upgrading to Xdebug 3, see the Upgrade guide.

    If you are using an AMP package, the Xdebug extension may be already installed. Refer to the instructions specific for your package.

Integrate Xdebug with the PHP interpreter

  1. Open the active php.ini file in the editor:

    1. In the Settings/Preferences dialog Ctrl+Alt+S, click PHP.

    2. On the PHP page that opens, click next to the CLI Interpreter field.

    3. In the CLI Interpreters dialog that opens, the Configuration file read-only field shows the path to the active php.ini file. Click Open in Editor.

  2. To disable the Zend Debugger and Zend Optimizer tools, which block Xdebug, remove or comment out the following lines in the php.ini file:

    zend_extension=<path_to_zend_debugger> zend_extension=<path_to_zend_optimizer>
  3. To enable Xdebug, locate or create the [xdebug] section in the php.ini file and update it as follows:

    [xdebug] zend_extension='<path to xdebug extension>' xdebug.remote_enable=1 xdebug.remote_host=127.0.0.1 xdebug.remote_port='<the port (9000 by default) to which Xdebug connects>'
    [xdebug] zend_extension='<path to xdebug extension>' xdebug.mode=debug xdebug.client_host=127.0.0.1 xdebug.client_port='<the port (9003 by default) to which Xdebug connects>'

    In PHP 5.3 and later, you need to use only zend_extension, not zend_extension_ts, zend_extension_debug, or extension.

    To enable multi-user debugging via Xdebug proxies, locate the xdebug.idekey setting and assign it a value of your choice. This value will be used to register your IDE on Xdebug proxy servers.

  4. Save and close the php.ini file.

  5. Verify Xdebug installation by doing any of the following:

    • In the command line, run the following command:

      The output should list Xdebug among the installed extensions:

    • Create a php file containing the following code:

      <?php phpinfo();

      Open the file in the browser. The phpinfo output should contain the Xdebug section:

Configure Xdebug in PhpStorm

  1. In the Settings/Preferences dialog Ctrl+Alt+S, select PHP.

  2. Check the Xdebug installation associated with the selected PHP interpreter:

    1. On the PHP page, choose the relevant PHP installation from the CLI Interpreter list and click next to the field. The list shows all the PHP installations available in PhpStorm, see Configure local PHP interpreters and Configure remote PHP interpreters.

    2. The CLI Interpreters dialog that opens shows the following:
      • The version of the selected PHP installation.

      • The name and version of the debugging engine associated with the selected PHP installation (Xdebug or Zend Debugger). If no debugger is configured, PhpStorm shows the corresponding message:

    Alternatively, open the Installation Wizard, paste the output of the phpinfo(), and click Analyze my phpinfo() output. Learn more about checking the Xdebug installation in Validate the Configuration of a Debugging Engine.

  3. Define the Xdebug behaviour. Click Debug under the PHP node. On the Debug page that opens, specify the following settings in the Xdebug area:

    • In the Debug port field, appoint the port through which the tool will communicate with PhpStorm.

      This must be the same port number as specified in the php.ini file:

      xdebug.remote_port='<the port (9000 by default) to which Xdebug connects>'
      xdebug.client_port='<the port (9003 by default) to which Xdebug connects>'

      By default, Xdebug 2 listens on port 9000. For Xdebug 3, the default port has changed from 9000 to 9003. You can specify several ports by separating them with a comma. By default, the Debug port value is set to 9001,9003 to have PhpStorm listen on both ports simultaneously.

    • To have PhpStorm accept any incoming connections from Xdebug engine through the port specified in the Debug port field, select the Can accept external connections checkbox.

    • Select the Force break at first line when no path mapping specified checkbox to have the debugger stop as soon as it reaches and opens a file that is not mapped to any file in the project on the Servers page. The debugger stops at the first line of this file and Examine/update variables shows the following error message: Cannot find a local copy of the file on server <path to the file on the server> and a link Click to set up mappings. Click the link to open the Resolve Path Mappings Problem dialog and map the problem file to its local copy.

      When this checkbox cleared, the debugger does not stop upon reaching and opening an unmapped file, the file is just processed, and no error messages are displayed.

    • Select the Force break at first line when a script is outside the project checkbox to have the debugger stop at the first line as soon as it reaches and opens a file outside the current project. With this checkbox cleared, the debugger continues upon opening a file outside the current project.

  4. In the External connections area, specify how you want PhpStorm to treat connections received from hosts and through ports that are not registered as deployment server configurations.

    • Ignore external connections through unregistered server configurations: Select this checkbox to have PhpStorm ignore connections received from hosts and through ports that are not registered as deployment server configurations. When this checkbox is selected, PhpStorm does not attempt to create a deployment server configuration automatically.

    • Break at first line in PHP scripts: Select this checkbox to have the debugger stop as soon as connection between it and PhpStorm is established (instead of running automatically until the first breakpoint is reached). Alternatively turn on the Run | Break at first line in PHP scripts option from the main menu.

    • Max. simultaneous connections Use this spin box to limit the number of external connections that can be processed simultaneously.

By default, PhpStorm only listens for incoming IPv4 connections. To enable IPv6 support, you need to make adjustments in PhpStorm JVM options:

  1. Select Help | Edit Custom VM Options from the main menu.

  2. In the .vmoptions file that opens, delete the -Djava.net.preferIPv4Stack=true line.

  3. Restart PhpStorm.

Configure Xdebug for using in the On-Demand mode

Phpstorm

PhpStorm supports the On-Demand mode, where you can disable Xdebug for your global PHP installation and have it enabled automatically on demand only when you are debugging your command-line scripts or when you need code coverage reports. This lets your command line scripts (including Composer and unit tests) run much faster.

XamppPhpstorm Xdebug Xampp
  1. Disable Xdebug for command-line scripts:

    1. In the Settings/Preferences dialog Ctrl+Alt+S, go to PHP.

    2. From the PHP executable list, choose the relevant PHP interpreter and click next to it. In the CLI Interpreters dialog that opens, click the Open in Editor link next to the Configuration file: <path to php.ini> file. Close all the dialogs and switch to the tab where the php.ini file is opened.

    3. In the php.ini file, find the [xdebug] section and comment the following line in it by adding ; in preposition:

      ;[xdebug] ;zend_extension = '<path to xdebug extension>'
    4. Open the CLI Interpreters dialog and click next to the PHP executable field. PhpStorm informs you that debugger is not installed:

  2. To enable PhpStorm to activate Xdebug when it is necessary, specify the path to it in the Debugger extension field, in the Additional area. Type the path manually or click and select the location in the dialog that opens.

Configure Xdebug for using in the Just-In-Time mode

PhpStorm supports the use of Xdebug in the Just-In-Time (JIT) mode so it is not attached to your code all the time but connects to PhpStorm only when an error occurs or an exception is thrown. Depending on the Xdebug version used, this operation mode is toggled through the following settings:

  • Xdebug 2 uses the xdebug .remote_mode setting, which has to be set to jit.

  • Xdebug 3 uses the xdebug.start_upon_error setting, which has to be set to yes.

Phpstorm Xampp Debugger

The mode is available both for debugging command-line scripts and for web server debugging.

Depending on whether you are going to debug command-line scripts or use a Web server, use one of the scenarios below.

Command-line scripts

For debugging command-line scripts, specify the custom -dxdebug.remote_mode=jit (for Xdebug 2) or -dxdebug.start_upon_error=yes (for Xdebug 3) directive as an additional configuration option:

  1. In the Settings/Preferences dialog Ctrl+Alt+S, navigate to PHP.

  2. From the PHP executable list, choose the relevant PHP interpreter and click next to it.

  3. In the CLI Interpreters dialog that opens, click next to the Configuration options field in the Additional area.

  4. In the Configuration Options dialog that opens, click to add a new entry.

    • For Xdebug 2, type xdebug.remote_mode in the Configuration directive field and jit in the Value field.

    • For Xdebug 3, type xdebug.start_upon_error in the Configuration directive field and yes in the Value field.

    When you click OK, you return to the CLI Interpreters dialog where the Configuration options field shows -dxdebug.remote_mode=jit (for Xdebug 2) or -dxdebug.start_upon_error=yes (for Xdebug 3).

Web server debugging

  1. From the main menu, choose Run | Web Server Debug Validation.

  2. In the Validate Remote Environment that opens, choose the Web server to validate the debugger on.

    • Choose Local Web Server or Shared Folder to check a debugger associated with a local Web server.

      • Path to Create Validation Script: In this field, specify the absolute path to the folder under the server document root where the validation script will be created. For Web servers of the type Inplace, the folder is under the project root.

        The folder must be accessible through http.

      • URL to Validation Script: In this field, type the URL address of the folder where the validation script will be created. If the project root is mapped to a folder accessible through http, you can specify the project root or any other folder under it.

    • Choose Remote Web Server to check a debugger associated with a remote server.

      • Path to Create Validation Script: In this field, specify the absolute path to the folder under the server document root where the validation script will be created. The folder must be accessible through http.

      • Deployment Server: In this field, specify the server access configuration of the type Local Server or Remote Server to access the target environment. For details, see Configure synchronization with a Web server.

        Choose a configuration from the list or click Browse in the Deployment dialog.

  3. Click Validate to have PhpStorm create a validation script, deploy it to the target remote environment, and run it there.

  4. Open the php.ini file which is reported as loaded and associated with Xdebug.

  5. In the php.ini file, find the [xdebug] section.

    Change the value of the xdebug.remote_mode from the default req to jit.

    Change the value of the xdebug.start_upon_error from the default default to yes.

Phpstorm Xdebug Not Working

Configure Xdebug running in a Docker container

To configure Xdebug running in a Docker container, provide the Xdebug-specific parameters in the Dockerfile, for example:

RUN pecl install xdebug && docker-php-ext-enable xdebug && echo 'xdebug.remote_enable=on' >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini && echo 'xdebug.remote_host = host.docker.internal' >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini

Phpstorm Xdebug Xampp Crack

In this example, we're modifying /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini providing the remote_enable and remote_host Xdebug parameters.

Phpstorm 9 Download

Note that the xdebug.remote_host value should be replaced with the IP address of the machine where PhpStorm is running, which is accessible from the Docker container. If you are using Docker for Windows or Docker for Mac, you can set xdebug.remote_host to host.docker.internal, which automatically resolves to the internal address of the host, letting you easily connect to it from the container.

Configure Xdebug Phpstorm

RUN pecl install xdebug && docker-php-ext-enable xdebug && echo 'xdebug.mode=debug' >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini && echo 'xdebug.client_host = host.docker.internal' >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini

In this example, we're modifying /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini providing the mode and client_host Xdebug parameters.

Note that the xdebug.client_host value should be replaced with the IP address of the machine where PhpStorm is running, which is accessible from the Docker container. If you are using Docker for Windows or Docker for Mac, you can set xdebug.client_host to host.docker.internal, which automatically resolves to the internal address of the host, letting you easily connect to it from the container.

Configure Xdebug running on a Vagrant instance

To configure Xdebug running on a Vagrant instance, connect to the Vagrant machine and provide the Xdebug-specific parameters in the php.ini file:

Phpstorm
[xdebug] zend_extension='<path to xdebug extension>' xdebug.remote_enable=1 xdebug.remote_host=10.0.2.2 xdebug.remote_port=9000

Note that the xdebug.remote_host value is 10.0.2.2. This is the gateway used in the default Vagrant setup, which allows connecting from the instance to host where PhpStorm is running.

[xdebug] zend_extension='<path to xdebug extension>' xdebug.mode=debug xdebug.client_host=10.0.2.2 xdebug.client_port=9003

Note that the xdebug.client_host value is 10.0.2.2. This is the gateway used in the default Vagrant setup, which allows connecting from the instance to host where PhpStorm is running.
