note 118981 added to function.empty

If you test an element of an array (like $_POST['key]), it test if the key doesn't exist or if it exist if its value is empty and never emit a warning. For who don't want to test what happen if passed an array element here is my test and result. <?php $a = array(); $b = array('key'); $c = array('key' => false); $d = array('key' => 'La verdad nos hace libres'); echo (empty($a['key'])?'A empty':'A not empty'), ' - ', (empty($b['key'])?'B empty':'B not empty'), ' - ', (empty($c['key'])?'C empty':'C not empty'), ' - ', (empty($d['key'])?'D empty':'D not empty'); ?> And the result is: A empty - B empty - C empty - D not empty ---- Server IP: 72.52.91.14 Probable Submitter: 85.48.117.217 ---- Manual Page -- http://php.net/manual/en/function.empty.php Edit -- https://master.php.net/note/edit/118981 Del: integrated -- https://master.php.net/note/delete/118981/integrated Del: useless -- https://master.php.net/note/delete/118981/useless Del: bad code -- https://master.php.net/note/delete/118981/bad+code Del: spam -- https://master.php.net/note/delete/118981/spam Del: non-english -- https://master.php.net/note/delete/118981/non-english Del: in docs -- https://master.php.net/note/delete/118981/in+docs Del: other reasons-- https://master.php.net/note/delete/118981 Reject -- https://master.php.net/note/reject/118981 Search -- https://master.php.net/manage/user-notes.php
