Configure debugging

Edit on GitHub

This document describes how to configure debugging in a local environment.

Xdebug is the default debugging tool for Spryker in Docker. Enable Xdebug:

docker/sdk {run|start|up} -x

Configure PhpStorm for Xdebug

To configure PhpStorm for Xdebug, take the following steps.

Install the prerequisites

  1. Install PhpStorm, Early Access Program preferred. You can download PHPStorm using the Jetbrains Toolbox.
  2. Install Xdebug.
  3. Optional: Install the Xdebug browser extension. In the extension settings, for IDE key, enter PHPSTORM.

Configure Xdebug

    1. Depending on your requirements, for Debug port, enter one or more ports. For example, to support Xdebug 2 and 3, enter 9000,9003.
    2. Select the Can accept external connections checkbox.
    3. Clear the Force break at first line when no path mapping specified and Force break at first line when a script is outside the project checkboxes.


  1. In the External connections section:

    1. For Max. simultaneous connection, select 5.
    2. Clear the Ignore external connections through unregistered server configurations and Break at first line in PHP scripts checkboxes.

    2. For Host, enter spryker.
    3. For Port, enter 80.
    4. In the Debugger drop-down menu, select Xdebug .
    5. Select the Use path mappings checkbox.
    6. Set the absolute path to the /data folder on the server for the folder with your Spryker project files. Servers config

Troubleshooting the debugging configuration in PhpStorm

when A breakpoint does not work.


  1. In PhpStorm, go to Preferences > PHP > Debug.
  2. Select the Break at first line in PHP scripts checkbox.
  3. Rerun or refresh your application. The app should break at the index.php and open a debugger pane in the IDE: debugger-pane
  4. Re-try your breakpoints.

Configure VSCode for Xdebug

To configure VSCode for Xdebug, take the following steps.

Install the prerequisites

  1. Install VScode, the Insiders version preferred.
  2. Install Xdebug.
  3. Install PHP Debug Extension.

Set up a Launch.json

Create a Launch.json:

    "version": "0.2.0",
    "configurations": [

            "name": "Listen for XDebug",
            "type": "php",
            "request": "launch",
            "port": 9003,
            "runtimeExecutable": "/absolute/path/php/bin",
            "pathMappings": {
                "/data": "${workspaceFolder}"
            "log": true,
            "xdebugSettings": {
                "max_data": 65535,
                "show_hidden": 1,
                "max_children": 100,
                "max_depth": 5

Avoiding timeouts

The default Zed request timeout is 60 seconds. Debugging requests often take more than 60 seconds to complete. In this case, a browser stops the connection.

To avoid Zed request timeouts, adjust your configuration as follows:

$config[ZedRequestConstants::CLIENT_OPTIONS] = [
    'timeout' => 300,

300 seconds should suit most cases, but you can increase it or even make it unlimited by defining the value as 0.

Unlimited timeout

If you set unlimited timeout, this affects all Zed requests, not only debugging ones.

Switching to the debugging mode

There are several ways to switch to the debugging mode:

  • To debug a web application, pass the XDEBUG_SESSION cookie with a string value. If you are using the Xdebug helper browser extension, in the extension menu, select debug.
  • To run all applications in the debugging mode, run docker/sdk {run|start|up} -x.
  • To debug a console command in cli, run it with the -x option.

Debugging with Xdebug

This section describes how to debug with Xdebug.

Debugging applications with Xdebug

To debug an application:

  1. Make a breakpoint. Breakpoint

  2. Select Start listening. Start listening

  3. Open the application in a browser.

  4. Navigate to the action you have configured the breakpoint for in step 1. The debugging process should be running in the IDE. Debug process

Debugging console commands and tests with Xdebug

To debug a console command or a test in a debugging mode, run it with the -x option.

Find several examples below:

  • docker/sdk cli -x
  • docker/sdk cli -x console queue:worker:start
  • docker/sdk console -x queue:worker:start
  • docker/sdk testing -x codecept run -codeception.yml

The PHPMD command requires the PHPMD_ALLOW_XDEBUG env variable for debug mode:

docker/sdk cli -x
PHPMD_ALLOW_XDEBUG=true vendor/bin/phpmd ...


Issue: Receiving no connection in PhpStorm or similar

In rare cases, docker containers running in the debug mode stop XDebug connections after waking computer from the sleep mode. So if you don’t get a banner “Debug session was finished without being paused”, run the following command:

docker/sdk stop && docker/sdk run -x
