Anonymous classes contain a non printable \0 character. trigger_error apparently ignores the message length and as such misses the latter half of the message.

I guess a workaround would be:

preg_replace('/[\x00]/', '',$class::class);

I quickly had a look yesterday, but we're relying on some API that doesn't support \0 in messages, which is annoying (printf etc).

This seems to work: https://gist.github.com/nielsdos/79419e56941ae80062e1b382c7e275f9
But I didn't test that very thoroughly, also there are two remaining issues:

• One related to syslog (marked with XXX)
• The compiler gives warnings because the format attribute is used on the Zend's print-family functions and the compiler doesn't know about the %Z format that we implement

The fix looks correct to me, although tbh I'm not sure it's worthwhile. For %Z, the _unchecked variants of these functions should be used. Also a nit: I think for fwrite, size and nmemb are supposed to be reversed.

Idk either, I don't like the complication.

TIL, thx

Hm indeed, confusing function and confusing naming.

I would like to see this fixed as well, it's definitely weird and buggy to see error messages cut-off. From the perspective of a PHP user \0 isn't really special.

I don't object to fixing this. @nielsdos Feel free to create a PR.
