note 125938 added to language.operators.errorcontrol

It's still possible to detect when the @ operator is being used in the error handler in PHP8. Calling error_reporting() will no longer return 0 as documented, but using the @ operator does still change the return value when you call error_reporting(). My PHP error settings are set to use E_ALL, and when I call error_reporting() from the error handler of a non-suppressed error, it returns E_ALL as expected. But when an error occurs on an expression where I tried to suppress the error with the @ operator, it returns: E_ERROR | E_PARSE | E_CORE_ERROR | E_COMPILE_ERROR | E_USER_ERROR | E_RECOVERABLE_ERROR (or the number 4437). I didn't want to use 4437 in my code in case it changes with different settings or future versions of PHP, so I now use: <?php function my_error_handler($err_no, $err_msg, $filename, $linenum) { if (error_reporting() != E_ALL) { return false; // Silenced } // ... } ?> If the code needs to work with all versions of PHP, you could check that error_reporting() doesn't equal E_ALL or 0. And, of course, if your error_reporting settings in PHP is something other than E_ALL, you'll have to change that to whatever setting you do use. ---- Server IP: 45.112.84.4 Probable Submitter: 45.112.85.246 (proxied: 2601:601:e03:ed0:d929:bf9a:4221:cf4f) ---- Manual Page -- http://php.net/manual/en/language.operators.errorcontrol.php Edit -- https://master.php.net/note/edit/125938 Del: integrated -- https://master.php.net/note/delete/125938/integrated Del: useless -- https://master.php.net/note/delete/125938/useless Del: bad code -- https://master.php.net/note/delete/125938/bad+code Del: spam -- https://master.php.net/note/delete/125938/spam Del: non-english -- https://master.php.net/note/delete/125938/non-english Del: in docs -- https://master.php.net/note/delete/125938/in+docs Del: other reasons-- https://master.php.net/note/delete/125938 Reject -- https://master.php.net/note/reject/125938 Search -- https://master.php.net/manage/user-notes.php
