Code

The first test, "lambda", was:

$a = $GLOBALS['a'];
$callback = function($n) { return $n; };
for($i = 0; $i < 100; ++$i) {
	array_map($callback, $a);
}

The second test, "create_function()", was:

$a = $GLOBALS['a'];
$callback = create_function('$n', 'return $n;');
for($i = 0; $i < 100; ++$i) {
	array_map($callback, $a);
}
