Found this:

Maybe out of date, but apparently there's no other way but to write it
yourself.

<wild guess>
echo strlen(serialize($array));

If you're wondering how much memory your array is taking up engine
wise you can do a few little tests. Of course you could do the echo
serialize form but that isn't going to tell you how much memory it
uses internally within the engine itself. Granted this might not
either, but it is at least a little closer.

var_dump(memory_get_usage());

$array = array(
1 => 'one',
2 => 'two',
3 => 'three'
);

var_dump(memory_get_usage());

Output:
int(53464)
int(53928)
