Answer 1

You can use strict comparison:

in_array($object, $array, TRUE);

Usage example:

$a = new stdClass();
$a->x = 42;

$b = new stdClass();
$b->y = 42;

$c = new stdClass();
$c->x = 42;

$array = array($a,$b);

echo in_array($a, $array, true); // 1
echo in_array($b, $array, true); // 1
echo in_array($c, $array, true); //
