Include path and __autoload function in php

Question

I am trying to convert several php scripts to use the __autoload function. Now I can use include and require functions, such as:

require_once('path/to/script.php');

But inside the __autoload function, I cannot use the line above. I have to use this:

require_once('absolute/path/to/script.php');

Why does the __autoload function not seem to use the include path that I specified in php.ini?

Answer 1

Do not use __autoload... It has several drawbacks (including a limit of one per run). Use spl_autoload_registerif you are on 5.2+ instead .

So what I usually do is have a class:

class AutoLoader {
    protected static $paths = array(
        PATH_TO_LIBRARIES,
    );
    public static function addPath($path) {
        $path = realpath($path);
        if ($path) {
            self::$paths[] = $path;
        }
    }
    public static function load($class) {
        $classPath = $class; // Do whatever logic here
        foreach (self::$paths as $path) {
            if (is_file($path . $classPath)) {
                require_once $path . $classPath;
                return;
            }
        }
    }
}
spl_autoload_register(array('AutoLoader', 'load'));

, , " " , AutoLoader::AddPath($path);. (IMHO).

    if (file_exists("includes/{$class}.php")) {
        require_once("includes/{$class}.php");
    }
