URL parsing in order to use as a variable

[dylan]

Can anyone tell me if it's possible to enter a URL such as

http://www.streetfish.co.uk/1234

and take the number and pass it to the index.php script (where the
number is the user's mySQL user id.

This is pretty much what happens with tinyurl.com (as far as I
understand) but the examples I have read regarding this are using
different technologies.

If anyone can help, or if you can let me know if you've seen a similar
example, I'd appreciate some help.

Thanks,

Dylan

The functionality you want is in the web server itself.
Look in the Apache docs for something like (never done it) URL
Rewriting.

Ok, I don't know exactly, but you would use an .htaccess script I
expect to get the address sent to a php script, then from that use the
substr command to take out the main url leaving you with 1234 which you
could put into a variable. You could just have something like this
though : streetfish.co.u k/link?id=1234 much easier.

@Peter: His server is ISS so he wont find anything helpful looking at
the apache docs, look at the errorpages.

On Apache, there is an AcceptPathInfo= on directive, which should do
what you want (the corresponding variable in PHP is PATH_INFO - see
http://php.net/reserved.variables). Only it doesn't. I logged this as
a bug at: http://issues.apache.org/bugzilla/show_bug.cgi?id=8880 but it
was denied (they suggest a workaround at the bottom of the report). I
never did understand why they didn't want to do fix it.

I also didn't implement their suggestion because I now (as I suspect
most others) use url rewriting, a little of which is described at:
http://www.codecomments.com/archive2...-8-574178.html (of course,
there is more documentation at
http://httpd.apache.org/docs/2.0/urlmapping.html and
http://httpd.apache.org/docs/2.0/misc/rewriteguide.html)

By the way, notice that PHP address above. It's doing the same thing
you want done. Don't know what to tell you for non Apache.

Re: URL parsing in order to use as a variable

<?
$url= $_SERVER['PHP_SELF']; //gives you url
$userid=strrchr ($url,"/"); // gives u /1234
$userid=substr( $file,1); // gives u 1234 by eliminating /

/* i think u got it */
?>

<?php

echo $_SERVER['HTTP_HOST']; //outputs sitename.com etc
echo $_SERVER['REQUEST_URI']; //outputs /index.php etc
?>
