note 107251 added to function.array-search

I have found that this function only works if the key is specifically defined in the array definition. For example, this will work: $abc = array('a'=> 0, 'b'=> 1, 'c'=>2); $key= array_search(1, $abc); echo $key; //Will return 'b' However, this will NOT work: $abc = array('a', 'b', 'c'); $key= array_search(1, $abc); echo $key; //null ---- Server IP: 69.147.83.197 Probable Submitter: 67.53.118.2 ---- Manual Page -- http://www.php.net/manual/en/function.array-search.php Edit -- https://master.php.net/note/edit/107251 Del: integrated -- https://master.php.net/note/delete/107251/integrated Del: useless -- https://master.php.net/note/delete/107251/useless Del: bad code -- https://master.php.net/note/delete/107251/bad+code Del: spam -- https://master.php.net/note/delete/107251/spam Del: non-english -- https://master.php.net/note/delete/107251/non-english Del: in docs -- https://master.php.net/note/delete/107251/in+docs Del: other reasons-- https://master.php.net/note/delete/107251 Reject -- https://master.php.net/note/reject/107251 Search -- https://master.php.net/manage/user-notes.php
