Heredoc/Nowdoc highlighting issue

[zonuexe]

Since this pattern consists of \w+, consideration to _ is missing. Moreover, it does not correspond to the <<<"heredoc" style.

Nowdoc highlighting breaks for me in this file, it seems that the cause is somewhere in the preceding comment.

@efermi Thank you for reporting. I reproduced the problem in my environment.

This is certainly similar to the existing problem, but the situation is a bit complicated.

This looks like a problem with the PHP Mode coloring algorithm, so I'll find and investigate a lot of time.

Thank you for looking into it.

It looks fine in Emacs 28 and above.
