Change url without actually changing it.

[Markus]

Is there a way i could get

http://somesite.com/viewer/someimage.jpg

to be recognised as

http://somesite.com/viewer/?id=someimage.j pg

I know i could rewrite the url with .htaccess but i don't want to change the lettering in the url.

The thing im trying to get at is;
how myspace do: myspace.com/username
but the 'username' isn't an actual directory.
I'm guesing it is read as myspace.com/?user=username

Hmm, anyone?

Thanks.

I'm not all that experienced with all this, but would it not be possible to replace "([a-zA-Z0-1_-]+)" with "(\w+)"?

I was aware that there was some common expression that could take care of it, but i didn't know what it was.

Thanks Atli.

Not quite \w is for the following range:-

a-zA-Z0-9_

so misses out the - but of course you could add that in. I personally however prefer whenever possible to use ranges so that it is easier to see what a regular expression does. Unless you specifically know what \w does you will have problems decoding the regexp whereas you have a better chance with actually using the ranges.

Yeh, i was going to stick with

a-zA-Z0-9_-

For that very reason. Although knowing about \w is helpful for future reference :)
