snip
mixed array_search ( mixed needle, array haystack [, bool strict])

Searches haystack for needle and returns the key if it is found in
the array, FALSE otherwise.

When ever you see that a function that returns mixed with a possible
FALSE Boolean value. You must always test your result as follows:

if ($j !== FALSE) {
  // found an item
} else {
  // no item found
}
