Basic Array in PHP

I'd like to add even numbers to an array and then echo it out, here's my code but it just shows array() when I print...what am i doing wrong?

<?php
    $x =88;
    $numbers = array();
    while ($x % 2 == 0 && $x <= 99) {
        $numbers[] = "$x";
        $x++;
    }
    print_r($numbers);
?>

You should move the "evenness" test from the while loop, and move it to a conditional within the while loop:

<?php
    $x = 88;
    $numbers = array();
    while ($x <= 99) {
        if ($x % 2 == 0) {
            $numbers[] = $x;
        }
        $x++;
    }
    print_r($numbers);
?>

As you have currently written the while loop, it ends if the number is not even. You should also remove the quotes from $x when you add to the $numbers array.
