note 102856 added to function.key

Just to illustrate the behaviour of the internal pointer when you add items. Adding to an array does not affect the internal pointer. $a = array(); var_dump(key($a)); // null $a[] = "jump"; var_dump(key($a)); // 0 $a[] = "lazy"; var_dump(key($a)); // 0 end($a); var_dump(key($a)); // 1 $a[] = "fox"; var_dump(key($a)); // 1 ---- Server IP: 92.48.74.199 Probable Submitter: 79.135.106.49 ---- Manual Page -- http://www.php.net/manual/en/function.key.php Edit -- https://master.php.net/note/edit/102856 Del: integrated -- https://master.php.net/note/delete/102856/integrated Del: useless -- https://master.php.net/note/delete/102856/useless Del: bad code -- https://master.php.net/note/delete/102856/bad+code Del: spam -- https://master.php.net/note/delete/102856/spam Del: non-english -- https://master.php.net/note/delete/102856/non-english Del: in docs -- https://master.php.net/note/delete/102856/in+docs Del: other reasons-- https://master.php.net/note/delete/102856 Reject -- https://master.php.net/note/reject/102856 Search -- https://master.php.net/manage/user-notes.php
