Note Submitter: Ray.Paseur Gmail ---- The comment here is factually inaccurate: http://us2.php.net/manual/en/book.array.php#96219 PHP loose data typecasting is applicable to array keys, and if you use a numeric string for an array key, you will get a numbered index. And it will overwrite any existing numbered index in the array. This script outputs: array(1) { [3000000000]=> bool(true) } array(1) { [3000000000]=> bool(true) } <?php // RAY_temp_johnmarc.php ini_set('display_errors', TRUE); error_reporting(E_ALL); // KEY AS INTEGER $key = 3000000000; $DATA[$key] = true; var_dump($DATA); // KEY AS INTEGER, BUT CAST AS STRING $key = 3000000000; $DATA["$key"] = true; var_dump($DATA);
