Summary0000811: PHP Documentation Link
DescriptionPHP has the built in config vars docref_root and docref_ext for generating links in error messages. Xdebug should use them instead of its own manual_url.
You could use a default value if they are not set, but there shoudnt be 2 vars for the same purpose...

The links generated by PHP are not clickable in the browser (see screenshot)
Steps To ReproduceSet docref_root and force a php error...
TagsNo tags attached.
Operating System
PHP Version5.4.0

I do not disagree and it was kind of interesting to figure out why I added it in the first place. Seems like I added it on June 6th, 2002: . This was before PHP introduced docref on August 8th, 2002:

I'll get rid of it in 2.2.1.

Thanks for the fix, but there are still two small issues:

1. The slash needs to be part of the variable (PHPs behaviour):
return xdebug_sprintf("<a href='%s%s%s' target='_new'>%s</a>\n",
(PG(docref_root) && PG(docref_root)[0]) ? PG(docref_root) : "",

2. The nameformat in the downloadable manual is i.e "function.mysqli-connect" instead of "mysqli_connect"

So now I get instead of

This format is also supported by the online doc:

I was trying to setup Xdebug v2.2.1 at Apache 2.4.2/PHP 5.4.4 at a Linux machine and i got just there, with the same issue. So, as Virsacer reporter, i have the same problem: currently, its not possible to make Xdebug works with PHP.ini "docref_root" local documentation linkage, at a dev machine.

The sintax used by Xdebug linkage is point to function references is wrong to pharse local manual entries. Even online entries too.

I believe the "function.*" should be added at the pharsed issue, as well as the correct handler-mapping pointed above. Maybe, this just get working fine if it only follows the default PHP.ini "docref_root" behavior.

Best regards.

I've further committed code for this - it should work now.
