note 117676 added to function.implode

null values are imploded too. You can use array_filter() to sort out null values. <?php $ar = array("hello", null, "world"); print(implode(',', $ar)); // hello,,world print(implode(',', array_filter($ar, function($v){ return $v !== null; }))); // hello,world ?> ---- Server IP: 213.172.110.13 Probable Submitter: 84.226.39.6 ---- Manual Page -- http://php.net/manual/en/function.implode.php Edit -- https://master.php.net/note/edit/117676 Del: integrated -- https://master.php.net/note/delete/117676/integrated Del: useless -- https://master.php.net/note/delete/117676/useless Del: bad code -- https://master.php.net/note/delete/117676/bad+code Del: spam -- https://master.php.net/note/delete/117676/spam Del: non-english -- https://master.php.net/note/delete/117676/non-english Del: in docs -- https://master.php.net/note/delete/117676/in+docs Del: other reasons-- https://master.php.net/note/delete/117676 Reject -- https://master.php.net/note/reject/117676 Search -- https://master.php.net/manage/user-notes.php
