note 109335 added to function.is-null

Using === NULL instead of is_null(), is actually useful in loaded server scenarios where you have hundreds or thousands of requests per second. Saving microseconds on a lot of "simple" operations in the entire PHP execution chain usually results in being able to serve more pages per second at the same speed, or lowering your cpu usage. People usually write very bad and slow code. ---- Server IP: 69.147.83.197 Probable Submitter: 131.111.7.69 ---- Manual Page -- http://www.php.net/manual/en/function.is-null.php Edit -- https://master.php.net/note/edit/109335 Del: integrated -- https://master.php.net/note/delete/109335/integrated Del: useless -- https://master.php.net/note/delete/109335/useless Del: bad code -- https://master.php.net/note/delete/109335/bad+code Del: spam -- https://master.php.net/note/delete/109335/spam Del: non-english -- https://master.php.net/note/delete/109335/non-english Del: in docs -- https://master.php.net/note/delete/109335/in+docs Del: other reasons-- https://master.php.net/note/delete/109335 Reject -- https://master.php.net/note/reject/109335 Search -- https://master.php.net/manage/user-notes.php
