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); ---- Server IP: 64.71.164.2 Probable Submitter: 98.169.58.122 ---- Manual Page -- http://www.php.net/manual/en/book.array.php Edit -- https://master.php.net/note/edit/104465 Del: integrated -- https://master.php.net/note/delete/104465/integrated Del: useless -- https://master.php.net/note/delete/104465/useless Del: bad code -- https://master.php.net/note/delete/104465/bad+code Del: spam -- https://master.php.net/note/delete/104465/spam Del: non-english -- https://master.php.net/note/delete/104465/non-english Del: in docs -- https://master.php.net/note/delete/104465/in+docs Del: other reasons-- https://master.php.net/note/delete/104465 Reject -- https://master.php.net/note/reject/104465 Search -- https://master.php.net/manage/user-notes.php
