Server.MapPath - PHP equivalent?

[mralston]

Is there a function (or has someone else written one) that does the equivalent of ASP's Server.MapPath?

I know there are a few that will sort of do it, but quite often they will return stuff like ../../../../whatever - which is pretty much useless for my purposes! I'm after the full path on the local file system.

Say there is a page on a website named "index.html"...I'd like a function that would convert that to "/usr/local/home/httpd/htdocs/index.html" or "c:\apache\htdocs\index.html".

Any ideas?

echo realpath(substr($PHP_SELF, 1));

//or

echo realpath("index.php"); 

Hope it helps

or

echo $_ENV["SCRIPT_FILENAME"];

or

echo $_SERVER["SCRIPT_FILENAME"];

does the samething.

and Da_Silvy, $PHP_SELF has pretty much gone to the wayside if used by itself.

Thanks, da_silvy. That was just the function I needed. Funny, I looked right through the filesystem section in the PHP help file but never saw that one staring me in the face!!



scoutt, normally those would be fine, but I needed to know the full path of a file that would not necessarily be the PHP script currently executing. I needed it for a little security precaution - a page on the site was going to be including other files from paths provided in the query string - I needed to make sure that the file to be included was actually within the website and not some other file like /etc/passwd...the contents of which would be then shown to the end user
BTW, did you loose your VB Forums account aswell?

[scoutt]

yes I did and they haven't added it back as of yet.

ahh I see what you are doing.

Who's the cheeky chappy on your avatar?
Something else I seem to have lost.

don't know if you have found the thread in the feedback forum, but you can ask for your posts and stuff back. just give a jingle in that thread and show where you have posted that says guest and not yet registered.

D'ya know, I think I've asked you that before, Scoutt. Sudden deja vu when I just read your reply.

Mmmm...a post in that thread, I have made.

[scoutt]

probably, it does sound familiar.
