I'm trying to add a number to a value in an array. Pretend I have this: $new_value = array('orange', 2); $arr = array(
    array('blue', 4),
    array('orange', 5),
    array('green', 6));
I want to add the new value to the existing matching array element, so I end up with this: $arr = array(
    array('blue', 4),
    array('orange', 7),
    array('green', 6));
Seems like it should be really simple but all the ways I can figure out to do it are too kludgey.
It's rather easy: for ($i=0; $i<count($arr); $i++) {
    if ($arr[$i][0] == $new_array[0]) {
        $arr[$i][1] += $new_array[1];
        break; // Optional - means the first "orange" found will be
               // updated only
    }
