RE: [PHP] Re: PHP5 and pass by reference bug.

Yeah, I get what references are. The point is that when it was on the user to decide, they could do it. Now that PHP5 makes you put the & in the function declaration instead of the passing parameter, you don't know what the user is going to send. Therefore it renders the & in the function declaration a useless thing. I could have this function Function add (&$a, &$b) { return ($a + $b); } And as a user I could use it like so: $x = 5; $y = 10; add($x, $y); Or I could also use it like this: add(5,10); But since the function is now responsible in PHP5 to use the & [since passing add(&$x, &$y); is now invalid], it makes my function add basically useless. > -----Original Message----- > From: Red Wingate [mailto:redeye@erisx.de] > Sent: Friday, July 16, 2004 5:35 PM > To: php-general@lists.php.net > Subject: [PHP] Re: PHP5 and pass by reference bug. > > Maybe you recheck the dokumentation on what exactly > referenzes are.
