PHP 'illegal offset'

Question

I have a simple PHP blackjack script that I seem to be getting errors in.

The part of code causing the problem is this;

function evaluateHand($hand) {
    global $faces;
    $value = 0;
    foreach ($hand as $card) {
        if ($value > 11 && $card['face'] == 'a') {
            $value = $value + 1;
        }
        else {
            $value = intval($value) + intval($faces[$card['face']]); <----- error
        }
    }
    return $value;
}

The error is "Warning: Illegal offset 'face'" on the line I've pointed to above.

What's causing this? Or how I could fix it?

This isn't [the error I get](http://jsbin.com/makeregufa/1/edit?js,console). And that doesn't look like JavaScript. Are you sure you aren't writing PHP? — Quentin, Mar 29 '17 at 18:35
Could you add with which value you call this (PHP) function? — trincot, Mar 29 '17 at 18:35
Here is a repl to see how this can happen in action https://repl.it/GlFZ/1 — 000, Mar 29 '17 at 18:48

Illegal offset means you are requesting an array key that doesn't exist. In this case, the array in $card has no key face when the error is thrown.
