How To Debug PHP scripts with PhpStorm


JetBrains PhpStorm is a commercial IDE for PHP built on JetBrains’ IntelliJ IDEA platform.

PhpStorm provides intelligent editor for PHP code, HTML and #JavaScript with on-the-fly code analysis and automated refactoring for PHP and #JavaScript code. Code completion supports PHP 5.3 including namespaces and closures.

Edit php.ini, located at /xampp/php/php.ini if you use XAMPP

Turn the following properties

implicit_flush = On  ; xdebug.remote_enable  ; Type: boolean, Default value: 0  ; This switch controls whether Xdebug should try to contact a debug client which is listening on the  ; host and port as set with the settings xdebug.remote_host and xdebug.remote_port. If a connection  ; can not be established the script will just continue as if this setting was Off.  xdebug.remote_enable = 1  ; xdebug.remote_handler  ; Type: string, Default value: dbgp  ; Can be either 'php3' which selects the old PHP 3 style debugger output, 'gdb' which enables the GDB  ; like debugger interface or 'dbgp' - the brand new debugger protocol. The DBGp protocol is more  ; widely supported by clients. See more information in the introduction for Remote Debugging.  xdebug.remote_handler = "dbgp"  ; xdebug.remote_host  ; Type: string, Default value: localhost  ; Selects the host where the debug client is running, you can either use a host name or an IP  ; address.  xdebug.remote_host = "localhost"  ; xdebug.remote_port  ; Type: integer, Default value: 9000  ; The port to which Xdebug tries to connect on the remote host. Port 9000 is the default for both the  ; client and the bundled debugclient. As many clients use this port number, it is best to leave this  ; setting unchanged.  xdebug.remote_port = 9000

Restart Apache by using XAMPP control panel. Xdebug should now be correctly configured, You can check this installation by using the online installation check page here
