Undeclare a class in PHP [closed]

Answer 1

It is not possible to "undeclare" a class.

You should probably look into PHP's namespacing or, use a convention for naming your classes similar to

Application_Module_Class

so you would be calling

$x = new Application_Foo_Bar;

to include the Bar class from the Foo module

This also lends itself quite well to using autoload functions
