Version of Apache on Windows is 2.4.48 x64, it is also the latest one.

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

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

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?

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.

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?

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.

Right.  And when you change the setting, you need to restart
Apache for that change to be effective.  However, depending on
other INI directives, the code may still be read from the file
cache, what's likely what has happened to you.

opcache.save_comments is only about doc block comments (i.e. those
starting with /**); other comments are always stripped.

No feedback was provided. The bug is being suspended because
we assume that you are no longer experiencing the problem.
If this is not the case and you are able to provide the
information that was requested earlier, please do so and
change the status of the bug back to "Re-Opened". Thank you.

A checked the opcache.file_update_protection enabled setting, and it is not set in both 7.x and 8.0, so I guess it is not the case of the problem.

Any ideas?

Sorry for the delay

>opcache.save_comments is only about doc block comments

Can you confirm that doc block comments are really deleted on Windows 7-10 with any value of opcache.file_update_protection setting? I don't see it working. Maybe it's a bug in previous versions, not in 8.0?

Yes (PHP-7.4).  As I said above, the compiled files may be read
from the file_cache, even after you made changes to the OPcache
configuration and restarted Apache.

Is there a way to clear that file cache for me to verify? I see there is no bug in 8.0, just to figure things out.

The location of the file cache is set by opcache.file_cache; you
can just delete this folder (including all subitems).  Or, for
testing, you can leave the setting empty (opcache.file_cache=).

All the information presented here is beneficial for me. (https://github.com)(https://www-adpvantage.com)
