How can the include_path be adjusted in PHP scripts to include PEAR classes in a specific directory?

To adjust the include_path in PHP scripts to include PEAR classes in a specific directory, you can use the set_include_path function to add the directory containing the PEAR classes to the include_path. This way, when you require or include PEAR classes in your PHP script, PHP will look in the specified directory.

<?php
// Add the directory containing PEAR classes to the include_path
set_include_path(get_include_path() . PATH_SEPARATOR . '/path/to/pear/classes');

// Now you can require or include PEAR classes in your PHP script
require_once 'PEAR_Class.php';
?>
