Configuring a Debugging Engine

This section describes how to configure two most popular tools used in PHP debugging:

• Xdebug
• Zend Debugger

These tools cannot be used simultaneously because they block each other. To avoid this problem, you need to update the corresponding sections in the php.ini file. To open the active php.ini file in the editor:

1. Open the Settings / Preferences Dialog by pressing Ctrl+Alt+S or by choosing File | Settings for Windows and Linux or PhpStorm | Preferences for OS X, and click PHP under Languages&Frameworks.
2. On the PHP page that opens, click next to the CLI Interpreter field.
3. In the CLI Interpreters dialog box that opens, the Configuration File read-only field shows the path to the active php.ini file. Click Open in Editor.
