note 68619 added to function.array-key-exists

At least in PHP 4.4.0, array_key_exists is inconsistently sensitive to different data types. For example, if your first argument is a double and the keys in your array are integers, array_key_exists will always return false. If you then cast the first argument to an integer, or even to a string, then you can successfully match. I haven't tested all the possibilities, to see when it'll tolerate different data types and when it won't, so the easiest and safest solution is to cast your first argument to match the data type of the keys. ---- Server IP: 66.163.161.117 Probable Submitter: 130.91.13.51 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.array-key-exists.php Edit -- https://master.php.net/note/edit/68619 Del: integrated -- https://master.php.net/note/delete/68619/integrated Del: useless -- https://master.php.net/note/delete/68619/useless Del: bad code -- https://master.php.net/note/delete/68619/bad+code Del: spam -- https://master.php.net/note/delete/68619/spam Del: non-english -- https://master.php.net/note/delete/68619/non-english Del: in docs -- https://master.php.net/note/delete/68619/in+docs Del: other reasons-- https://master.php.net/note/delete/68619 Reject -- https://master.php.net/note/reject/68619 Search -- https://master.php.net/manage/user-notes.php
