List of Reserved Words
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
This section lists standard predefined classes. Miscellaneous extensions define other classes which are described in their reference.
Standard Defined Classes
These classes are defined in the standard set of functions included in the PHP build.
- Directory
- The class from which dir is instantiated.
- stdClass
- __PHP_Incomplete_Class
Predefined classes as of PHP 5
These additional predefined classes were introduced in PHP 5.0.0
- exception
- php_user_filter
Special classes
Following identifiers may not be used as a class name as they have special purpose.
- self
- parent

It's handy to have a array of the reserved classes.....
var_dump (get_declared_classes ());
