Question

I have an array of values that can be DISABLED or ENABLED, so I want to know how many are there ENABLED. Here is a piece of code:

$list = array(
$variable1,
$variable2,
$variable3,
$variable4
);
$count = count($list);

Thanks for any reply.

UPDATE: the values are NOT true and or false but ENABLE / DISABLE. Do your answers apply in this case? Thanks again.

Answer 1

If the only valid options are boolean TRUE and FALSE, then

$countTrue = array_sum($list);

EDIT

with ‘ENABLE’ and ‘DISABLE’ as the possible values:

$countTrue = array_reduce(
    $list,
    function($counter, $value) {
        return $counter + ($value == 'ENABLE');
    },
    0
);
