问题描述
我最近在开发服务器上改用了PHP 7，到目前为止运行良好-
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)以来，不再可以访问utf8_decode和utf8_encode函数.但是，它们在PHP7的早期版本中.调用时，将引发致命错误.
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.
我了解到这些功能是由mbstring扩展名提供的，我用var_dump(extension_loaded('mbstring'));检查了该扩展名.
I read that these functions are provided by the mbstring extension, which I checked with var_dump(extension_loaded('mbstring')); is loaded.
如何使以上功能再次起作用?
How can I get the above functions to work again?
