note 78569 added to language.operators.errorcontrol

The @ operator can also be prepended to literals (like strings), as they're also statements -- it will suppress any notice about uninitialized variables. If you want to silence a more complex expression (@ is unary), use braces. <?php // variable interpolation $str = @"Then I said: '$maybeunset'."; // integer stuffs $result = @2 * 3 / 0; // = @(2) * 3 / 0 - WRONG (warning) $result = @(2 * 3 / 0); // RIGHT (no warning), $result is false ?> @John Chilton's post: As omelnyk said, isset is a language construct and NOT a function, and an @ token is not allowed there. @isset makes no sense, because under ANY circumstances isset stays quiet. Also, "using it with variables all the time" is a VERY bad idea, because it will make your code EXTREMELY slow. Crank your error_reporting down then. ---- Server IP: 217.13.201.10 Probable Submitter: 85.176.240.124 ---- Manual Page -- http://www.php.net/manual/en/language.operators.errorcontrol.php Edit -- https://master.php.net/note/edit/78569 Del: integrated -- https://master.php.net/note/delete/78569/integrated Del: useless -- https://master.php.net/note/delete/78569/useless Del: bad code -- https://master.php.net/note/delete/78569/bad+code Del: spam -- https://master.php.net/note/delete/78569/spam Del: non-english -- https://master.php.net/note/delete/78569/non-english Del: in docs -- https://master.php.net/note/delete/78569/in+docs Del: other reasons-- https://master.php.net/note/delete/78569 Reject -- https://master.php.net/note/reject/78569 Search -- https://master.php.net/manage/user-notes.php
