		0 ignored issues – show Coding Style introduced 2017-10-11 12:57 UTC by Report Bug Copy Issue Report `case` statements should be defined using a colon. As per the PSR-2 coding standard, case statements should not be wrapped in curly braces. There is no need for braces, since each case is terminated by the next `break`. There is also the option to use a semicolon instead of a colon, this is discouraged because many programmers do not even know it works and the colon is universal between programming languages. switch ($expr) { case "A": { //wrong doSomething(); break; } case "B"; //wrong doSomething(); break; case "C": //right doSomething(); break; } To learn more about the PSR-2 coding standard, please refer to the PHP-Fig. Loading history...
