Debug with PhpStorm and Xdebug

Configuration

Have a look in your php.ini configuration file and enable Xdebug, add the following statement:

[Xdebug]
zend_extension=<full_path_to_xdebug_extension>
xdebug.remote_enable=1
xdebug.remote_host=<the host where PhpStorm is running (e.g. localhost)>
xdebug.remote_port=<the port to which Xdebug tries to connect on the host where PhpStorm is running (default 9000)>

for example with Wamp configurated I have:

; XDEBUG Extension

zend_extension = "d:/wamp/bin/php/php5.5.12/zend_ext/php_xdebug-2.2.5-5.5-vc11.dll"
;
[xdebug]
xdebug.remote_enable = 1
xdebug.profiler_enable = off
xdebug.profiler_enable_trigger = off
xdebug.profiler_output_name = cachegrind.out.%t.%p
xdebug.profiler_output_dir = "d:/wamp/tmp"
xdebug.show_local_vars=0
xdebug.remote_host=localhost
xdebug.remote_port=9000

Restart Apache

Then in a shell execute this command to verify if Xdebug is correctly running:

php --version

Once your PHP project is created, if you want to debug it, you have to set up your php interpreter and Xdebug in settings:

GO TO SETTINGS

INTERPRETER FOR WAMP 2.5 ON WINDOWS

SETUP YOUR PHP INTERPRETER

SET UP XDEBUG CONF

DEFINE APPLICATION TO TEST WITH

DEFINE SERVER CONF

Run/Debug Configurations completed

Run/Debug Configurations FINALY


Configuration adjustment if php-fpm is used.

If it is, the Xdebug port 9000 conflicts with the default php-fpm port.

You must chose a different port, either in php-fpm, or Xdebug.

Also, when php-fpm is used, you must ALSO restart php-fpm for any changes to the php-ini files to take effect.


Use of a Xdebug.log file

In some case you will need to keep on logs what is going on you server. A log file might help you to solve your problems.

The official documentation will help you to perform this functionality

It can help a lot when trying to figure out what is broken in the installation.
