heres what I want to do. Instead of editing files I would like to have some sort of plug-in system. I can think of only one way to do this and that would be ot include everyfile in a DIR then call that same function (they would have same # of paramaters) but the displays a nameforce error. how can I do this?

This is essentially the Command Pattern. Each file in your directory has a class of the same name in it. each class has a common method that can be called. This is one form of polymorphism which is a foundation of OO. For example:
File foo.php contains:
Code: Select all
class foo {
public function run(myparam$);
// my code here
}
}
File bar.php contains:
Code: Select all
class bar {
public function run(myparam$);
// my code here
}
}
To run them:
Code: Select all
foreach (glob('mydir/*.php') as $name) {
include $name;
$class = str_replace('.php', '', $name);
$obj = new $class()
$obj->run($myparam);
}
