include_once Wrapper Class

There hase been some discussion in the recend days about the performance of include_once. Inlude_once is really slower than include. For the inclusion of the classes you can use
class_exists('PEAR') or require_once 'PEAR.php' (www.akbkhome.com/blog...);

You can also use this wrapper class for include_once and require_once, it is faster.

<?php
class includeWrapper{
    private static $paths = array();
    public static function includeOnce($path_file){
        if(!in_array($path_file,self::$paths)){
            include($path_file);
            self::$paths[] = $path_file;
        }
    }
    public static function requireOnce($path_file){
        if(!in_array($path_file,self::$paths)){
            require($path_file);
            self::$paths[] = $path_file;
        }
    }
}
includeWrapper::includeOnce("Class1.class.php");
includeWrapper::requireOnce("Class1.class.php");
includeWrapper::includeOnce("Class2.class.php");
?>
