File | Settings | PHP | Skipped Paths
On this page, specify the scripts requests to which you want IntelliJ IDEA to ignore during debugging. This approach can be useful, when your application contains scripts that use AJAX. Suppose you have a menu-ajax-script.php that "reloads" a part of your web page. This script works properly so you do not need to debug it. However, this script is still requested during the debugging session. To have incoming connections to this script ignored, add the menu-ajax-script.php script to the skipped paths list. You can also group such scripts into folders and add these folders to the "ignore list".
