Using Notepad++’s Function List plugin for PHP development

Using the Notepad++ Function List plugin you can filter out all of the required and included files in your current PHP file. To do so you will need a few things:

• Notepad++ (NPP)
• Function List plugin

Once you have installed the Function List plugin as the instructions say, open up Notepad++ and follow the instructions below.

1. Navigate in the File Menu to Plugins > Function List > Language Parsing Rules
2. Select PHP from the left hand column
3. Under the Group section click Add (You will now see newGroup listed below the Add / Delete buttons)
4. Click on newGroup and change the Group Properties Name to Include
5. Now under the Group Rules section make these changes (without the quotes):
   • Function Begin: “include[\s\w]*\(['"]“
   • Function List Name: “[\w\s\d\\/_.]*”

If you have a PHP file open that has functions and/or classes you can click the Try! button at the bottom of the window and you will see your included file paths show up in the Function List. Repeat this process to create a rule for required files as well. Once completed just click OK and you are done! Enjoy listing your included and required file paths in Notepad++.

**This will filter out the following in your Function List pane:

• include(‘file_path_here.php’);
• include (‘file_path_here.php’);
• include_once(‘file_path_here.php’);
• include_once (‘file_path_here.php’);
• require(‘file_path_here.php’);
• require (‘file_path_here.php’);
• require_once(‘file_path_here.php’);
• require_once (‘file_path_here.php’);
