PHP Simple Auto Load

Just wanna share my PHP autoload function.
In my application, I have several types of classes and may located in different folder such as :

• Helper
• Model
• Component
• Web Service
• etc
  

The easiest way to use the classes is to create an auto load function so the classes file will be included automatically.

Hope this could be useful to you too.

<?php
/**
 * Auto function
 * @param <string> $classname class name
 * @return <void> void
 */
function __autoload($classname) {
    global $global_helper_path;
    global $global_model_path;
    global $global_component_path;
    global $global_wsobject_path;

    //load helper
    $pos = strrpos($classname, "Helper");
    if ($pos === false) { // note: three equal signs
    } else {
        //print $classname;
        $filepath = "$global_helper_path/$classname.php";
        require_once "$filepath";
        return;
    }

    // load component
    $pos = strrpos($classname, "com_");
    if ($pos === false) { // note: three equal signs
    } elseif ($pos == 0) {
        $filepath = "$global_component_path/$classname/$classname.php";
        require_once "$filepath";
        return;
    }

    // load database driver
    $pos = strrpos($classname, "DB");
    if ($pos === false) { // note: three equal signs
    } elseif ($pos == 0) {
        $filepath = "$global_helper_path/database/$classname.php";
        require_once "$filepath";
        return;
    }

    // load model
    $pos = strrpos($classname, "Model");
    if ($pos === false) { // note: three equal signs
    } else {
        $filepath = "$global_model_path/$classname.php";
        require_once "$filepath";
        return;
    }

    // load webservice class
    $pos = strrpos($classname, "WS");
    if ($pos === false) { // note: three equal signs
    } elseif ($pos == 0) {
        $filepath = "$global_wsobject_path/$classname.php";
        require_once "$filepath";
        return;
    }
}

?>

PHP Web Service Library

I gave a look on my PHP web service class. It's quite hard to extends and create a new web service application. I search on Google and found several open source projects and gave them a test.

I found "php-webservice-class" is the best since the implementation is simple,easy and fully commented. It also use ReflectionClass, makes the code simpler without need to create phpDoc parser to get your parameter settings.

The project url:
http://code.google.com/p/php-webservice-class/


Update on 28th Feb 2011

The wsdl output is not standard. :(
You can't call the web service from other language.
I'm considering to use David Kingma library (my old library also based on his work) for replacement.
