Oh! hahah, no your documentation doesn't suck, though yes it is non-existent. My eye is what sucks, I thought you were creating new objects then destroying them immediately after, I glazed over the fact that you were just unsetting the variable holding the class name, not the object itself. So, let me try this again... when ever this construct is called it finds the list of files you've already included, and loads a new object into existence for each of those files that is a class (*.class.php). Interesting way to go about it.
Have you heard of the registry pattern? Check this out: Registry pattern
I use a version of it that automagically includes the file if necessary, so instead of including all the necessary files at the top of my script, anytime I call my load() method, it checks to see if it's in memory, and if not, includes it. Ala,
PHP Code:
/**
* Adds a new object instance of the specified class to the
* static registry library, and returns a reference
*
* @access public
* @static
* @param string $szModule The module the specified class belongs to
* @param string $szClass The name of the class
* @param mixed $mArgs Arguments to be passed to the object, can be a string or an array
* @return object Returns an instance of the specified object from the registry library
*/
static function load ($szModule, $szClass, $mArgs=null) {
$szFilename = PATH_TO_LIB."{$szModule}.{$szClass}.php";
$szClass = "tuatara_{$szModule}_{$szClass}";
if (!file_exists($szFilename)) throw new Exception("Library file cannot be found.");
if (!class_exists($szClass)) include($szFilename);
if (!array_key_exists($szClass, self::$_registry)) {
if (is_array($mArgs)) {
$pReflect = new ReflectionClass($szClass);
self::$_registry[$szClass] = $pReflect->newInstanceArgs($mArgs);
} else {
self::$_registry[$szClass] = new $szClass($mArgs);
}
}
return self::$_registry[$szClass];
}
Works beautifully.
