- Download the XDebug
extension compatible with your version of PHP
and save it in the php/ folder.
Note
The location of the php/ folder is defined during the installation of the PHP engine.
Tip
If you are using an AMP package, the XDebug extension may be already installed. Follow the instructions in the xdebug.txt.
- Locate and open the active php.ini file.
Tip
To find out which php.ini file is active, create and run a test file with phpinfo(), then search for the Loaded Configuration File.
- To disable the Zend optimizer, which blocks XDebug, remove the [Zend] section
or mark it as comment in the php.ini file:
[Zend] zend_extension_ts = "<path to ZendExtensionManager.dll>" zend_extension_manager.optimizer_ts = "<path to Zend Optimizer>" zend_optimizer.enable_loader = 0 zend_optimizer.optimization_level=15 zend_optimizer.license_path = Local Variables: tab-width: 4 End: - To enable XDebug, locate the [XDebug] section in the php.ini file
and update it as follows:
- For a thread-safe PHP engine, version 5.2:
[XDebug] zend_extension_ts="<path to php_xdebug.dll>" xdebug.remote_enable=true xdebug.remote_port="<the port for XDebug to listen to>" (the default port is 9000) xdebug.profiler_enable=1 xdebug.profiler_output_dir="<AMP home\tmp>" - For a non-thread-safe PHP engine, version 5.2:
[XDebug] zend_extension_nts="<path to php_xdebug.dll>" xdebug.remote_enable=true xdebug.remote_port="<the port for XDebug to listen to>" (the default port is 9000) xdebug.profiler_enable=1 xdebug.profiler_output_dir="<AMP home\tmp>" - For any PHP engine, version 5.3 and higher:
[XDebug] zend_extension="<path to php_xdebug.dll>" xdebug.remote_enable=1 xdebug.remote_port="<the port for XDebug to listen to>" (the default port is 9000) xdebug.profiler_enable=1 xdebug.profiler_output_dir="<AMP home\tmp>"
- For a thread-safe PHP engine, version 5.2:
- To enable multiuser 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.
- Save and close the php.ini file.
- Open the XDebug checker.
- Enter the output of the phpinfo().

On the Debug page that opens, specify the following settings in the XDebug area:
-
In the Debug Port text box, appoint the port through which the tool will communicate with IntelliJ IDEA.
This must be exactly the same port number as specified in the php.ini file:
xdebug.remote_port = <port_number>By default, Xdebug listens on port 9000.
- To have IntelliJ IDEA accept any incoming connections from XDebug engines through the port specified in the Debug port text box, select the Can accept external connections check box.
- To have addresses of variables shown during a debugging session, select the Show variables addresses check box.
- To have the debugging engine stop at the first line automatically, select the Stop at first line check box.
