Type check in all array elements

Question

Is there any simple way of checking if all elements of an array are instances of a specific type without looping all elements? Or at least an easy way to get all elements of type X from an array.

Answer 1

$s = array("abd","10","10.1");
$s = array_map( gettype , $s);
$t = array_unique($s) ;
if ( count($t) == 1 && $t[0]=="string" ){
    print "ok\n";
}
