note 102543 added to language.operators.errorcontrol

If you're wondering what the performance impact of using the @ operator is, consider this example. Here, the second script (using the @ operator) takes 1.75x as long to execute...almost double the time of the first script. So while yes, there is some overhead, per iteration, we see that the @ operator added only .005 ms per call. Not reason enough, imho, to avoid using the @ operator. <?php function x() { } for ($i = 0; $i < 1000000; $i++) { x(); } real 0m7.617s user 0m6.788s sys 0m0.792s vs <?php function x() { } for ($i = 0; $i < 1000000; $i++) { @x(); } real 0m13.333s user 0m12.437s sys 0m0.836s ---- Server IP: 72.55.140.6 Probable Submitter: 216.99.60.219 ---- Manual Page -- http://www.php.net/manual/en/language.operators.errorcontrol.php Edit -- https://master.php.net/note/edit/102543 Del: integrated -- https://master.php.net/note/delete/102543/integrated Del: useless -- https://master.php.net/note/delete/102543/useless Del: bad code -- https://master.php.net/note/delete/102543/bad+code Del: spam -- https://master.php.net/note/delete/102543/spam Del: non-english -- https://master.php.net/note/delete/102543/non-english Del: in docs -- https://master.php.net/note/delete/102543/in+docs Del: other reasons-- https://master.php.net/note/delete/102543 Reject -- https://master.php.net/note/reject/102543 Search -- https://master.php.net/manage/user-notes.php
