note 97476 added to function.explode

When explode is given an empty $string, it'll return an array with a single empty element. <?php # returns Array([0] => ); print_r(explode(',', '')); ?> This is not a bug, but it can be pretty tricky (especially with callbacks that expect a certain type of array). So, be sure to check your arrays. It's not a bug, because there's nothing to split. ---- Server IP: 64.71.164.2 Probable Submitter: 71.22.33.6 ---- Manual Page -- http://www.php.net/manual/en/function.explode.php Edit -- https://master.php.net/note/edit/97476 Del: integrated -- https://master.php.net/note/delete/97476/integrated Del: useless -- https://master.php.net/note/delete/97476/useless Del: bad code -- https://master.php.net/note/delete/97476/bad+code Del: spam -- https://master.php.net/note/delete/97476/spam Del: non-english -- https://master.php.net/note/delete/97476/non-english Del: in docs -- https://master.php.net/note/delete/97476/in+docs Del: other reasons-- https://master.php.net/note/delete/97476 Reject -- https://master.php.net/note/reject/97476 Search -- https://master.php.net/manage/user-notes.php
