Req #81058 [Com]: Inedible syntax porridge

Edit report at https://bugs.php.net/bug.php?id=81058&edit=1 ID: 81058 Comment by: a at b dot c dot de Reported by: zmfw1991 at gmail dot com Summary: Inedible syntax porridge Status: Not a bug Type: Feature/Change Request Package: Compile Warning Operating System: all? PHP Version: Irrelevant Block user comment: N Private report: N New Comment: You've discovered the concept of an empty loop (a loop "foreach()" containing an empty statement ";"). Empty statements are cromulent; they're allowed so one also has to allow loops to contain them. Empty loops have their uses. There is no PHP bug here, only a typo in coding.

But php doesn't do that. ------------------------------------------------------------------------ [2021-05-20 11:04:56] rtrtrtrtrt at dfdfdfdf dot dfd garbage in - garbage out ------------------------------------------------------------------------ [2021-05-20 11:02:49] zmfw1991 at gmail dot com No. This is bug! [RU] Правильнее было бы определять это как синтаксическую ошибку и выдавать предупреждение, но php сейчас это не обнаруживает, он не замечает лишнюю точку с запятой после if () но перед {}. Здесь возможно неявное и непредсказуемое поведение, притом что врядли кто-то будет писать и ожидать корректного поведения от странных конструкции таких как: if( expression ); { code } При этом PHP волне обнаруживает синтаксическую ошибку здесь, на слове else: if ( false ); { echo 'true'; } else { echo 'true'; } Но если else не указан, то PHP промолчит. Я на поиск такой ошибки убил час, а PHP молчит как партизан, она очень незаметна и не бросается в глаза, но это ошибка всё же. ------------------------------------------------------------------------ [2021-05-20 10:42:48] derick@php.net Sorry, but your problem does not imply a bug in PHP itself.
