On GitHub: https://github.com/php/php-src/pull/6545 Patch: https://github.com/php/php-src/pull/6545.patch Previous Comments: ------------------------------------------------------------------------ [2020-12-22 15:22:00] terrafrost@php.net Description: ------------ PHP 8.0.0 made it so that the bcmath functions (among others) "throw an Error exception if the validation of the parameters fails" but there's one condition in which a warning will still be triggered (as opposed to an exception being thrown). Test script: --------------- <?php bcadd('a', 'a'); Expected result: ---------------- throw new TypeError('bcadd(): Argument #1 ($num1) must be numeric'); or some such Actual result: -------------- trigger_error('bcadd: bcmath function argument is not well-formed', E_USER_WARNING); ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=80545&edit=1
