[RESOLVED] Checking for values in an array?

[my_name]

For an example, let's say I have an array containing these six values (not necessarily in this order):

(1,5,9,2,4,7)

How can I check whether the value 1 AND value 2 AND value 3 exist at the same time within this array? In this case, the check would turn out false because the value 3 doesn't exist within the array, even though value 1 and value 2 do exist.

Right now, I'm doing this:

if (strpos($myarray, "1") !== false && strpos($myarray,"2") !== false && strpos($myarray,"3") !== false) {
	echo "Values 1, 2, and 3 are present!";
}

This works so far, but it may not in the future if I have numbers larger than 9 (because then, checking for the value "1" will return true for 11, 12, 13, 14, 15, etc.). There has to be a better way, right?

In addition, I have to check not only for the existence of 1, 2, and 3 but for other combinations of values, as well, so it's going to look really messy if continue to use the above code to get it done.

Thanks!

$array = array(1, 5, 9, 2, 4, 7);
$to_find = array(1, 2, 3);
$all_in = true;
foreach ($to_find as $val) {
    if (!in_array($val, $array)) {
        $all_in = false;
        break;
    }
}

Thanks, that works great! I wish I would've known about the in_array function earlier.
