in_array with ints?

[ZachMEdwards]

I've got an array of ints.

I need to see if an index (for example 15) is in the array, and then read the value. The problem is that in_array is returning false even though it's (clearly) in the array.

$t = array(13 => 2, 15 => 9);
$x = intval('15');
die(in_array($x, $t) ? 'true' : 'false');

It says false every time.

Found the problem. in_array looks for a value and I'm looking for an index.

 

It's late
