    lets say i have an array like:

    Array ( [0] => [1] => 2 [2] => 3 [3] => 3 [4] => 3 )

    now i want to count the total number of items in the array so i use:

    count($items)

    however that counts the [0] key which has no value, is there a way to only count fields with a value.

    Well, an empty value is still a value. If you want to check for empty values, you probably will need to loop through the array to check each value like so:

    $count = 0;
foreach ($array as $val) {
	if ($val) $count++;
}
