[thelist] Dynamic if statement in PHP

[Daniel Kushner]

If you have an array : $arr =  array(true, true, true);

Something like this should work:


function validateArray($arr, $index = 0) {
	return $index >= count($arr) ?
		true :
		$arr[$index] && validateArray($arr, ++$index);
}


$value = validateArray($arr);


(didn't test it though)
