How do I count comma-separated values in PHP?

Question

I have a variable holding values separated by a comma (Implode), and I\'m trying to get the total count of the values in that variable. However. count() is just returning 1.

Answer 1

$schools = $_SESSION['sarray'];
$array = explode(',', $schools); array_walk($array, 'trim');
$count = count($array);

The array_walk($array, 'trim') will remove any trailing space in elements value. :)
