Creating a wrapper for a function with same name

Question

I saw a function in cakephp-1.2 core files.

/**
* Convenience method for header()
*
* @param string $status
* @return void
* @access public
*/
function header($status) {
  header($status);
}

see https://github.com/cakephp/cakephp/blob/1.2/cake/libs/controller/controller.php#LC638

What may the reason they are redefining the function with same name? Will it work? I think the header function will create infinite recursion. I don't know how to check whether it creates infinite recursion.

See the top of the code, line 40:

class Controller extends Object {

That method is Controller::header, so does not override header. You can't "override" PHP functions: you'll simply get an error.

More precisely, it does not *conflict* with `header`. – Jon Mar 16 '12 at 08:11
This is the right answer, but it is possible override functions - http://stackoverflow.com/questions/2326835/redefine-built-in-php-functions – Paul Dixon Mar 16 '12 at 08:14

Ok, it's not possible to override functions with a standard installation of PHP... – lonesomeday Mar 16 '12 at 15:53
