PHP Count How Many Times a Value Exists in Each Iteration of a Loop

Question

I have a loop like this:

foreach ($result_new as $count){
echo "<pre>"; print_r($count);
}

This is what is produced:

Array
(
[0] => Array
    (
        [0] => TomVanhecker
        [1] => PASS
        [2] => Array
            (
                [0] => Array
                    (
                    )

            )

    )

)

Array
(
[0] => Array
    (
        [0] => DonLay
        [1] => PASS
        [2] => Array
            (
                [0] => Array
                    (
                     [0] => ADDRESS CHECK FAILED
                    )

            )

    )

)

Array
(
[0] => Array
    (
        [0] => PetraBerumen
        [1] => REVIEW
        [2] => Array
            (
                [0] => Array
                    (
                        [0] => ADDRESS CHECK FAILED
                    )

            )

    )

[1] => Array
    (
        [0] => PetraBerumen
        [1] => REVIEW
        [2] => Array
            (
                [0] => Array
                    (
                        [0] => ADDRESS CHECK FAILED
                    )

            )

    )

[2] => Array
    (
        [0] => PetraBerumen
        [1] => REVIEW
        [2] => Array
            (
                [0] => Array
                    (
                        [0] => ADDRESS CHECK FAILED
                    )

            )

    )

)

What I need it to find out how many times "ADDRESS CHECK FAILED" appears in each iteration and then do a comparison. I have tried this:

foreach ($result_new as $count){
if ((in_array_r("ADDRESS CHECK FAILED", $count)) ){
$address++
}
if($address > 2){
echo "There was more than two address failures for this customer";
}

The problem is that the $address value continues to increment with each loop but I just want that loops current total.

"The problem is that the $address value continues to increment with each loop but I just want that loops current total." I'm assuming you mean you want to count the total number of occurrences in each $count array correct? If that's the case, the in_array_r function as defined here: gist.github.com/Billy-/bc6865066981e80e097f isn't going to cut it since it returns a boolean. You should modify it to return a count instead. — clarkatron

@clarkatron but what I want is to count how many times it is true but not for the entire loop just for the current and then start over...does that make sense? — Thomas C

Just need to reset $address value at the end of the foreach loop, so every time it will count the current element values instead of the entire loop

foreach ($result_new as $count){
    if ((in_array_r("ADDRESS CHECK FAILED", $count)) ){
        $address++;
    }

    if($address > 2){
       echo "There was more than two address failures for this customer";
    }

    $address = 0;
}

If I'm understanding the problem correctly, I think you need to do something like this:

function in_array_recursive_count($needle, $haystack, &$current = 0, $strict = false) {
    foreach ($haystack as $item) {
        if ($strict ? $item === $needle : $item == $needle) {
            $current++;
        }
        else if(is_array($haystack)) {
            in_array_recursive_count($needle, $haystack, $current, $strict);
        }
    }
    return $current;
}

Then, you'd use it like so:

foreach ($result_new as $count){
    $address = in_array_recursive_count("ADDRESS CHECK FAILED", $count);
    if($address > 2){
        echo "There was more than two address failures for this customer";
    }
}
