问题描述
我最近在我的开发服务器上切换到 PHP 7，它一直运行良好 - 直到现在.
I recently switched to PHP 7 on my development server, which has worked just fine - until now.
自从我更新到 PHP 7.0.3-10+deb.sury.org~trusty+1(今天早些时候)后，utf8_decode 和 utf8_encode 函数不再可用.然而，它们在早期版本的 PHP7 中.调用时，会引发致命错误.
Since I updated to PHP 7.0.3-10+deb.sury.org~trusty+1 (earlier today), the utf8_decode and utf8_encode functions are no longer accessible. They were, however, in previous versions of PHP7. When called, a fatal error is raised.
我读到这些函数是由 mbstring 扩展提供的，我用 var_dump(extension_loaded('mbstring')); 检查了该扩展.
I read that these functions are provided by the mbstring extension, which I checked with var_dump(extension_loaded('mbstring')); is loaded.
我怎样才能让上述功能再次工作?
How can I get the above functions to work again?
