in cases whether the key you are 'looking up' is numeric php doesn't
care whether you use an integer or string - as far as php is concerned
"1" and 1 point to exactly the same array item:
php -r '$v = array("foo","bar"); var_dump($v["0"],$v[0], $v["1"], $v[1]);'
I find this quite handy - though it does help to actually know about this
particular behaviour :-)
