note 107626 added to language.types.null

When you work with arrays, there is a difference between setting an element to NULL and unsetting it: <? $arr = Array(); $arr['IVO'] = 1; $arr['NIKI'] = '2'; $arr['IVO'] = NULL; var_dump($arr); // shows 2 elements unset($arr['IVO']); var_dump($arr); // shows 1 element ?> ---- Server IP: 217.75.128.29 Probable Submitter: 78.90.165.87 ---- Manual Page -- http://www.php.net/manual/en/language.types.null.php Edit -- https://master.php.net/note/edit/107626 Del: integrated -- https://master.php.net/note/delete/107626/integrated Del: useless -- https://master.php.net/note/delete/107626/useless Del: bad code -- https://master.php.net/note/delete/107626/bad+code Del: spam -- https://master.php.net/note/delete/107626/spam Del: non-english -- https://master.php.net/note/delete/107626/non-english Del: in docs -- https://master.php.net/note/delete/107626/in+docs Del: other reasons-- https://master.php.net/note/delete/107626 Reject -- https://master.php.net/note/reject/107626 Search -- https://master.php.net/manage/user-notes.php
