note 73926 added to function.empty

Speed comparisons between empty($foo) versus !$foo are pointless; you're saving what, a couple dozen nanoseconds? If you care that much you'll have to benchmark every single new version of PHP in case changes affect the relative speeds of your various methods, and then recode if one method overtakes another. Now THAT is a waste of time. Far more important is that your code says what you want it to mean. Besides, when $foo is not set empty($foo) is >1400% faster than !$foo (and that's AFTER suppressing the notice message). ---- Server IP: 203.89.181.184 Probable Submitter: 60.234.168.92 ---- Manual Page -- http://www.php.net/manual/en/function.empty.php Edit -- https://master.php.net/note/edit/73926 Del: integrated -- https://master.php.net/note/delete/73926/integrated Del: useless -- https://master.php.net/note/delete/73926/useless Del: bad code -- https://master.php.net/note/delete/73926/bad+code Del: spam -- https://master.php.net/note/delete/73926/spam Del: non-english -- https://master.php.net/note/delete/73926/non-english Del: in docs -- https://master.php.net/note/delete/73926/in+docs Del: other reasons-- https://master.php.net/note/delete/73926 Reject -- https://master.php.net/note/reject/73926 Search -- https://master.php.net/manage/user-notes.php
