Summary: getDocComment is not working correctly
Status: Assigned
Type: Bug
Package: Reflection related
Operating System: Windows 7 x64 Pro
PHP Version: 8.0.8

New Comment:
For me the comment is always missing with save_comments=0, regardless of how it looks like. That
also matches the implementation.
I suspect that the behavior you observed might be an artifact of having options like
opcache.file_update_protection enabled. If it's enabled and you access a file quickly after
modifying it, then it will not be cached and save_comments=0 will not take effect.

Ah, I got it. That was my fault with wrong configuration of opcache. I set save_comments to 0, that
was the reason of stripping this out.
But the behavior of that option has changed since 7.4 anyway (it ignored PHPdoc before?). Also I
don't understand why the comment is not stripped when the first line of PHPdoc contains just
one word.
Maybe that needs a fix?

OK, here is some more testing.
1. It is in fact bool(false) as you said
2. I enabled opcache log with level 4, and here is the output:
Mon Jul 19 02:39:30 2021 (9636): Message Cached script 'D:\xmessenger\bug.php'
Mon Jul 19 02:39:30 2021 (9636): Message Added key 'D:/xmessenger/bug.php'
No errors as you see.
3. Without opcache enabled it is really behaving correctly.
But still I consider this to be a bug. Have you tested with opcache extension on yourself? What is
your Windows version where you test?
I really need opcache for better performance on versions PHP from 5.4 and newer (though my PC is not
as terrible, the HDD disk performance is too bad even for lightweight PHP applications on PHP
versions 5.4+).
Btw, I can check it on Win 10 x64 with latest updates if you want.

I cannot reproduce the reported behavior.
Does this also happen when OPcache is disabled? Does
::getDocComment() really return an empty string, or maybe false
(use var_dump() instead of echo). Does the OPcache error log (you
may need to set opcache.error_log and should set
opcache.log_verbosity_level=4) give any hints?

extension=curl
extension=mbstring
extension=exif
extension=mysqli
extension=openssl
extension=pdo_mysql
zend_extension=opcache
Just this set. It is also the same as in 7.2 and 7.4

What PHP extensions do you have enabled through Apache? Especially interested in anything that
caches or "optimizes" code.
