Simple way for casting array of values to int

Heads up! This post was written 11 years ago. Some information might be outdated or may have changed since then.

Here is a simple way to cast all elements in array to integeres in php

$array = array('1', '24', 'da', 'fa24');
$array = array_map('intval', $array);

And yes it have overhead but for small arrays it is ideal solution instead of writing a classical foreach loop

$array = array('1', '24', 'da','fa24'); 
foreach($array as $k =>$v) { 	
	$array[$k] = (int)$v; 
}
