note 103690 added to control-structures.foreach

Hello Everyone Just wanted to point smth interesting i found out. $id = '3047'; $array = array ( '3047' => '', '3049' => '', '3074' => '' ); As you can see, all key's are numers but in string form. foreach ($przedmioty as $key => $val){ echo var_dump ($id); echo var_dump ($key); die(); } Will output string(4) "3066" int(3047) Foreach tries to convert key to int, if it succedes $key is reurned as int. (haven't tested double) Thus, you can't compare string with it with === operator. Tried to compare it with get to exclude which key shouln't be generated ---- Server IP: 69.147.83.197 Probable Submitter: 83.28.46.66 ---- Manual Page -- http://www.php.net/manual/en/control-structures.foreach.php Edit -- https://master.php.net/note/edit/103690 Del: integrated -- https://master.php.net/note/delete/103690/integrated Del: useless -- https://master.php.net/note/delete/103690/useless Del: bad code -- https://master.php.net/note/delete/103690/bad+code Del: spam -- https://master.php.net/note/delete/103690/spam Del: non-english -- https://master.php.net/note/delete/103690/non-english Del: in docs -- https://master.php.net/note/delete/103690/in+docs Del: other reasons-- https://master.php.net/note/delete/103690 Reject -- https://master.php.net/note/reject/103690 Search -- https://master.php.net/manage/user-notes.php
