note 69117 added to types.comparisons

the manual said "HTML Forms do not pass integers, floats, or booleans; they pass strings" while this is true, php will sometimes change the type to either type array, or possibly type integer(no, not a numeric string) if it was used as an array key. php seems to do this when it parses the request data into the predefined variable arrays. example: <input type="text" name="foo[5]"> <input type="text" name="foo[7]"> now obviously the browser will send those names as a string. but php will change thier type. <?php // $_POST['foo'] is an array var_dump($_POST['foo']); foreach ($_POST['foo'] as $key => $val) { // the keys 5 and 7 will be type integer var_dump($key); } ?> because of this, its also a good idea to check the types of your variables. ---- Server IP: 64.71.164.2 Probable Submitter: 64.121.72.103 ---- X-Spam-Status: No, hits=4.0 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER, HTML_20_30,HTML_MESSAGE autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/types.comparisons.php Edit -- https://master.php.net/note/edit/69117 Del: integrated -- https://master.php.net/note/delete/69117/integrated Del: useless -- https://master.php.net/note/delete/69117/useless Del: bad code -- https://master.php.net/note/delete/69117/bad+code Del: spam -- https://master.php.net/note/delete/69117/spam Del: non-english -- https://master.php.net/note/delete/69117/non-english Del: in docs -- https://master.php.net/note/delete/69117/in+docs Del: other reasons-- https://master.php.net/note/delete/69117 Reject -- https://master.php.net/note/reject/69117 Search -- https://master.php.net/manage/user-notes.php
