note 103756 added to function.empty

When you need to accept these as valid, non-empty values: - 0 (0 as an integer) - 0.0 (0 as a float) - "0" (0 as a string) <?php function is_blank($value) { return empty($value) && !is_numeric($value); } ?> This is similar to Rails' blank? method. ---- Server IP: 66.207.199.35 Probable Submitter: 207.6.121.48 ---- Manual Page -- http://www.php.net/manual/en/function.empty.php Edit -- https://master.php.net/note/edit/103756 Del: integrated -- https://master.php.net/note/delete/103756/integrated Del: useless -- https://master.php.net/note/delete/103756/useless Del: bad code -- https://master.php.net/note/delete/103756/bad+code Del: spam -- https://master.php.net/note/delete/103756/spam Del: non-english -- https://master.php.net/note/delete/103756/non-english Del: in docs -- https://master.php.net/note/delete/103756/in+docs Del: other reasons-- https://master.php.net/note/delete/103756 Reject -- https://master.php.net/note/reject/103756 Search -- https://master.php.net/manage/user-notes.php
