HTML errors not showing

I am trying to test PHP (7.2) HTML error reporting.

I have downloaded the "Many HTML files" archive from http://php.net/download-docs.php and unpacked it to:

/home/user/public_html/php/manual/php-chunked-xhtml/

In php.ini for apache I have set:

error_reporting = E_ALL
display_errors = On

html_errors = On
docref_root = "/~user/php/manual/php-chunked-xhtml/"
docref_ext = .html

and restarted the apache service.

As a test I do:

printf();

Which yields:

Warning: printf() expects at least 1 parameter, 0 given in /home/user/public_html/test/err.php on line 10

… but it is not linked to the manual pages. Text only.

What am I doing wrong here? Should there not be a link to printf()?

Edit:

phpinfo() say settings are as in ini (above). I have also tried to move the manual to /var/www/html/phpmanual, but same result. I also added

ini_set("html_errors", true);

to the test file, but no change in result.

The manual is browseable.

As for what I expect. Per manual one have:

html_errors boolean

If enabled, error messages will include HTML tags. The format for HTML errors produces clickable messages that direct the user to a page describing the error or function in causing the error. These references are affected by docref_root and docref_ext. If disabled, error message will be solely plain text.

Thought I would get a link to printf() as per example.

OK found it finally -- the HTML error messages don't include links for all possible errors. For example:

strcmp();

Generates the warning:

Warning: strcmp() expects exactly 2 parameters, 0 given

But there is no link to the strcmp() function page, even though one exists in the documentation pack. (function.strcmp.html)

However, this code:

preg_match('/', null);

Also produces a warning:

Warning: preg_match() [function.preg-match.html]: No ending delimiter '/' found

But this one does include the link. Not sure what the difference is, as they're both E_WARNING level messages and both have doc pages present.
