#162 PATH_INFO not available

[nwtn]

Some hosting environments (e.g. Dreamhost) don't expose PATH_INFO or ORIG_PATH_INFO, which causes problems. The required data should be available in other vars, though, such as SCRIPT_NAME, REQUEST_URI, etc.

Below is the output from var_dump($_SERVER) from a Dreamhost server with this issue (w/ identifying data removed). Let me know if you need more info.

Thanks for the fix. It would be easier for me to integrate it if you posted the output of var_export($_SERVER) - please do so if you can.

[Christian Weiske]

Could you do the same for the URL "/test.php/dummy"?

Also, do you get a PATH_INFO variable if you put "AcceptPathInfo On" in .htaccess?

[nwtn]

Interesting. When going to /test.php/dummy I do get a PATH_INFO variable, even without AcceptPathInfo On in the .htaccess (see below).

Going to /test/, however, still does not give a PATH_INFO variable, even with AcceptPathInfo On.

But this is fine; it's like it should behave.

Do you have problems with that? Which problems?

[nwtn]

Ya, now I'm second-guessing the whole thing. I'll have to take another look to figure out exactly what was happening. I will update this ticket with more info shortly.
