PHP if function is called, how to override it with another function

Question

Possible Duplicate:
Override default php function

Is there a way to detect that a function is being called and override with a separate function? I'm not sure function_exists does that.

I think your asking the wrong question. Why do you need to do this in the first place? — Kendall Hopkins, Nov 17 '10 at 05:26

Override default php function

You can use namespaces to override existing function names:
namespace blarg;
function basename() {
    return 'whatever';
}
$base = basename();
I.e., any call to basename() within the blarg namespace will use your new version of the function.

This only works for php 5.3.0 and newer. – tmartin314 Nov 17 '10 at 00:04

The override_function() function may be what you need, but it seems ugly.

However, using namespaces or inheritance are probably better options.

I think this requires PECL or something – tmartin314 Nov 17 '10 at 00:09

Why do you want to? There is probably a better solution to the original problem.

Also, do you want to override a built in PHP function, or one that you have written yourself. Is it a method on an object, or a static function?
