Problem creating a helper (Error undefined offset)

As array indexes could be anything, you can't trust count($array). You can have array that looks like this:

Code:

$array[1] = 'a';
$array[1000] = 'b';
$array[-1] = 'c';

Better option would be to check if array element has been set with said index and then do the check for array element value:

Code:

$found = isset($array[$v]) && $iten == $array[$v] ? true : '';
