Re: OOP, dynamic class extention

php is not c, you can't use constants this way. Jackson Miller wrote:

I want to be able to set a base class in a settings file, and then have other classes extend the base class, but PHP won't let me do what I have tried. I get the following error: Fatal error: Class cepweb: Cannot inherit from undefined class my_base_class in /home/me/my_child_class.php on line 10 ex: <?php // settings to be set on install of the app define("MY_BASE_CLASS","base_class"); define("MY_BASE_CLASSFILE","base_class.php"); // require the class file require_once(MY_BASE_CLASSFILE); class my_child_class extends MY_BASE_CLASSFILE { // yada yada } ?> Any thoughts on ways to overcome this? I have tried using a variable instead of a constant, but it didn't work. -Jackson
