note 111091 added to function.array-filter

If you want a quick way to remove NULL, FALSE and Empty Strings (""), but leave values of 0 (zero), you can use the standard php function strlen as the callback function: eg: <?php // removes all NULL, FALSE and Empty Strings but leaves 0 (zero) values $result = array_filter( $array, 'strlen' ); ?> ---- Server IP: 192.41.42.26 Probable Submitter: 117.53.84.123 ---- Manual Page -- http://php.net/manual/en/function.array-filter.php Edit -- https://master.php.net/note/edit/111091 Del: integrated -- https://master.php.net/note/delete/111091/integrated Del: useless -- https://master.php.net/note/delete/111091/useless Del: bad code -- https://master.php.net/note/delete/111091/bad+code Del: spam -- https://master.php.net/note/delete/111091/spam Del: non-english -- https://master.php.net/note/delete/111091/non-english Del: in docs -- https://master.php.net/note/delete/111091/in+docs Del: other reasons-- https://master.php.net/note/delete/111091 Reject -- https://master.php.net/note/reject/111091 Search -- https://master.php.net/manage/user-notes.php
