note 115033 added to function.in-array

I have noted some strange behavior of the in_array() function if you have a hash like $haystack=array ( '123'=>'some value', '0125'=>'some value'); If I test now: if (in_array('23',$haystack)) // here also TRUE is returned I switched instead to if(isset($haystack['23'])) // which return correct FALSE Maybe this helps others too. ---- Server IP: 192.35.244.50 Probable Submitter: 193.187.235.17 ---- Manual Page -- http://php.net/manual/en/function.in-array.php Edit -- https://master.php.net/note/edit/115033 Del: integrated -- https://master.php.net/note/delete/115033/integrated Del: useless -- https://master.php.net/note/delete/115033/useless Del: bad code -- https://master.php.net/note/delete/115033/bad+code Del: spam -- https://master.php.net/note/delete/115033/spam Del: non-english -- https://master.php.net/note/delete/115033/non-english Del: in docs -- https://master.php.net/note/delete/115033/in+docs Del: other reasons-- https://master.php.net/note/delete/115033 Reject -- https://master.php.net/note/reject/115033 Search -- https://master.php.net/manage/user-notes.php
