note 95938 added to reserved.variables.post

When you have a form with some radio: <?php <form method='post'> <input type='radio' name='55' value='1' > <input type='radio' name='55' value='2' > <input type='radio' name='55' value='3' > <input type='radio' name='55' value='4' > <input type='submit' value='ok' > </form> ?> if the name of the radio is a number will be returned by $_POST as INT!!!! not string as the manual says if the name of the radio is 'test' will be of course returned ad string. So your post array will look like this: <?php array 167302 => string '167308' (length=6) 167314 => string '167344' (length=6) 167347 => string '5867521' (length=7) '3754952706' => string '3754952706' (length=10) '3744466946' => string '3744466946' (length=10) '3740271617' => string '3740271617' (length=10) '3749709826' => string '3749709826' (length=10) '3749708801' => string '1' (length=1) 'meta' => array 'hasJavascript' => string '0' (length=1) 'timeToComplete' => string '1264769572.6144' (length=15) 'Submit' => string 'Next' (length=4) ?> Note the first 3 keys are int not string This could affect you if you do some operations for example if you do an array_merge with your post values: <?php $arr1 = array( 167302 => '167308', 167314 => '167344', 167347 => '5867521', '3754952706' => '3754952706', '3744466946' => '3744466946', '3740271617' => '3740271617', '3749709826' => '3749709826', '3749708801' => '1' ); $arr2 = array( 'meta' => array ( 'hasJavascript' => '0', 'timeToComplete' => '1264769572.6144' ) ); ?> if you do : <?php $values = array_merge($arr1, $arr2);//this is done by zend in $form->getValues() ?> guess what will be the result? your numeric keys will be reindexed starting from 0. and your post values will look like this: <?php 0 => string '167308' (length=6) 1 => string '167344' (length=6) 2 => string '5867521' (length=7) '3754952706' => string '3754952706' (length=10) '3744466946' => string '3744466946' (length=10) '3740271617' => string '3740271617' (length=10) '3749709826' => string '3749709826' (length=10) '3749708801' => string '1' (length=1) 'meta' => array 'hasJavascript' => string '0' (length=1) 'timeToComplete' => string '1264769572.6144' (length=15) ?> ---- Server IP: 69.147.83.197 Probable Submitter: 132.185.240.121 ---- Manual Page -- http://www.php.net/manual/en/reserved.variables.post.php Edit -- https://master.php.net/note/edit/95938 Del: integrated -- https://master.php.net/note/delete/95938/integrated Del: useless -- https://master.php.net/note/delete/95938/useless Del: bad code -- https://master.php.net/note/delete/95938/bad+code Del: spam -- https://master.php.net/note/delete/95938/spam Del: non-english -- https://master.php.net/note/delete/95938/non-english Del: in docs -- https://master.php.net/note/delete/95938/in+docs Del: other reasons-- https://master.php.net/note/delete/95938 Reject -- https://master.php.net/note/reject/95938 Search -- https://master.php.net/manage/user-notes.php
