推荐答案

最终 try-catch块已添加到PHP 5.5中，该代码仍在开发中，因此可能无法使用它的原因是因为您使用的是PHP 5.4或更早版本。

The finally block of try-catch was added in PHP 5.5 which is still in development so the likely reason it isn't working for you is because you are using PHP 5.4 or earlier.

除非他们将其反向移植到早期的PHP版本中，或者您使用的是5.5版，否则您将无法最终使用。

You won't be able to use finally unless they backport it into an earlier PHP version or you are on a 5.5 release.
