throwing is done conditionally (see throwUnexpectedTypeException). Thus if the method throws, $e changes, otherwise $e stays as the original TypeError. This is exactly the logic we need here.

OK, I missed the rethrow below (this code should be cleaned to use finally
instead in 3.0+)

Quoting #18032: > it appears that the current implementation is error prone because it throws a `\TypeError` that is an `Error` in PHP 7 but a regular `Exception` in PHP 5 because it uses the Symfony polyfill. Programs wrote in PHP 5 and catching all exceptions will catch this "custom" `\TypeError ` but not those wrote in PHP 7. It can be very hard to debug. > In this alternative implementation: > * catching type mismatch is considered a bug fix and applied to Symfony 2.3 > * for every PHP versions, a domain exception is thrown Commits ------- 5fe2b06 [PropertyAccess] Reduce overhead of UnexpectedTypeException tracking 10c8d5e [PropertyAccess] Throw an UnexpectedTypeException when the type do not match
Isn't this a BC break? PHP 7 code that previously caught TypeError will not work anymore, or am I missing something? |
