note 99676 added to function.in-array

If you have an array like: $arr = array(0,1,2,3,4,5); in_array(NULL, $arr) returns true because you have 0 in your array. That is, in_array does not use === for equal check. ---- Server IP: 208.69.120.55 Probable Submitter: 12.153.137.113 ---- Manual Page -- http://www.php.net/manual/en/function.in-array.php Edit -- https://master.php.net/note/edit/99676 Del: integrated -- https://master.php.net/note/delete/99676/integrated Del: useless -- https://master.php.net/note/delete/99676/useless Del: bad code -- https://master.php.net/note/delete/99676/bad+code Del: spam -- https://master.php.net/note/delete/99676/spam Del: non-english -- https://master.php.net/note/delete/99676/non-english Del: in docs -- https://master.php.net/note/delete/99676/in+docs Del: other reasons-- https://master.php.net/note/delete/99676 Reject -- https://master.php.net/note/reject/99676 Search -- https://master.php.net/manage/user-notes.php
