note 112885 added to function.explode

Note that while the documentation states the "If limit is set and positive," passing a null-value will still result in triggering the "limit is zero" case (as of PHP 5.4.17). When passing through values (such as using explode to implement an interface method), you'll need to explicitly check that the limit has been set: <?php public function split($string, $delimiter, $limit = null) { return isset($limit) ? explode($delimiter, $string, $limit) : explode($delimiter, $string); } ?> Failing to check $limit and simply passing through a null-value will return the same value as if $limit were 0 or 1. To clarify, all of the following will return the same value: <?php explode($string, $delimiter, null); explode($string, $delimiter, 0); explode($string, $delimiter, 1); ?> ---- Server IP: 69.147.83.199 Probable Submitter: 138.236.71.114 ---- Manual Page -- http://php.net/manual/en/function.explode.php Edit -- https://master.php.net/note/edit/112885 Del: integrated -- https://master.php.net/note/delete/112885/integrated Del: useless -- https://master.php.net/note/delete/112885/useless Del: bad code -- https://master.php.net/note/delete/112885/bad+code Del: spam -- https://master.php.net/note/delete/112885/spam Del: non-english -- https://master.php.net/note/delete/112885/non-english Del: in docs -- https://master.php.net/note/delete/112885/in+docs Del: other reasons-- https://master.php.net/note/delete/112885 Reject -- https://master.php.net/note/reject/112885 Search -- https://master.php.net/manage/user-notes.php
