I have a PHP file at my server root.. index.php .. which include
's .. DIR/main.php
Now .. DIR/main.php .. include
's many nearby PHP files using relative URLs using .. include("./common1.php");
Any way I can change the relative-URL base path so when including "DIR/main.php" It can relatively access its nearby PHP files like "DIR/common1.php", instead of trying to find "common1.php" at the site root.
First, set the "relative-URL base path" to your directory
set_include_path( get_include_path() . '/DIR' );
Second, include your file!
require( 'main.php' );
That should work though I've not tested it.
