List of Keywords
In response to the note below mine,
This list is not incomplete. Read the Manual folks, its listed there plain and simple:
"This section lists standard predefined classes. Miscellaneous extensions define other classes which are described in their reference."
Depending on what extensions you have, they might define their own classes. This list is just the standard classes as defined by PHP with no regards to extensions.
Predefined Classes

- Directory

Predefined classes as of PHP 5
These additional predefined classes were introduced in PHP 5.0.0.
- Exception

It's handy to have a array of the reserved classes.....

if you want a Dynamic class you can extend from, add atributes AND methods on the fly you can use this:
<?php
class Dynamic extends stdClass{
public function __call($key,$params){
if(!isset($this->{$key})) throw new Exception("Call to undefined method ".get_class($this)."::".$key."()");
$subject = $this->{$key};
call_user_func_array($subject,$params);
}
}
?>
this will accept both arrays, strings and Closures:
<?php
$dynamic->myMethod = "thatFunction";
$dynamic->hisMethod = array($instance,"aMethod");
$dynamic->newMethod = array(SomeClass,"staticMethod");
$dynamic->anotherMethod = function(){
echo "Hey there";
};
?>
then call them away =D
