What is the include_path configuration in PHP

The include_path configuration in PHP is a setting that determines the directory locations where PHP looks for files when using functions like include, require, include_once, and require_once. By default, PHP may not have the necessary paths configured to find your files, so adjusting this setting can help avoid errors when including files from different directories.

You can set the include_path in the php.ini configuration file, or you can set it at runtime using the set_include_path() function or the ini_set() function.

Here’s a simple example of how to set the include_path at runtime:


include_path PHP configuration include require include_once require_once php.ini
