What is |
This class is from a potential future implementation of PHP 8 attributes in the friendly-exception package, related to Issue #16 (yiisoft/friendly-exception#16). Currently, this class doesn't exist in the official friendly-exception package. My PR adds defensive coding to ensure error-handler works correctly both with current versions (where this class doesn't exist) and with future versions (if/when PHP 8 attributes are implemented). I created test files that use this attribute to verify the defensive coding works properly. I've marked these tests as skipped when the attribute class is not available. If you prefer, I can remove the attribute-related test files and only keep the safety checks for the htmlEncode method, which fixes a real issue with TypeError when encoding exception objects. |

I like the concept. It allows marking expceptions as friendly without extending the interface and is a good addition to what we already have. That's of course, works for static text solutions only but in many cases these are enough. |

Where do you expect an exception? I'd remove try/catch

You're right, the try/catch block isn't necessary here. When checking for the FriendlyException attribute, it would be better to let any exceptions propagate normally, making potential issues easier to discover. I'll remove the try/catch block. Thank you for the suggestion!

…ibute - Remove unnecessary try/catch blocks as suggested in PR review
This PR fixes two issues in HtmlRenderer:
htmlEncode()function by properly converting Throwable object to string before encodingFriendlyExceptionattribute when the class is not availableThese changes allow the error handler to work properly with different versions of the friendly-exception package, making it more robust.
The changes are needed because some tests were failing with:
TypeError: HtmlRenderer::htmlEncode(): Argument #1 ($content) must be of type string, RuntimeException givenError: Attribute class "Yiisoft\FriendlyException\Attribute\FriendlyException" not foundThis implementation adds proper type checking and class existence verification to prevent errors.
