TalkPHP - View Single Post - Anonymous Functions in PHP 5.3.0, deprecates create_function

I've seen in PHP 5.3.0 which has been recently released, allows for anonymous functions assigned to variables, so instead of doing this:

Example #1

PHP Code:


			
function Add($a,$b) { return $a + $b; }



$A = 'Add';

$var1 = 2;

$var2 = 2;



printf('%d', $A($var1,$var2));

Example #2

PHP Code:


			


$A = create_function('$args', 'return $args[0] + $args[1];');



printf('%d', $A(2,2));

We can do:

PHP Code:


			
$A = function($a, $b) {

 return $a + $b;

}

which I like this a lot, reminds me a lot like javascript, i hope this can be done with classes aswell, like so:

PHP Code:


			


$A::MyMethod = public static function( $a, $b ) { return $a + b; }

On-Topic about PHP 5.3 aswell, I tried to install it on xampp, but I still happen to get a parse error by trying to do the simplest of putting in "namespace Project;". even though the module is loaded in apache ( at least in the config )
