Why doesn't this regex work?

lil' finger exercise for y'all?

I'm absolutely amazed by my vserver and the first thing I wanted to do with it is install openphoto (because it rocks and I dislike flickr+picasa more and more).

The rewrite rule for openphoto to have nice urls seems to be pretty easy (as shown in the installation guide):

^/(.*)\?*$

index.php?__route__=/$1

the idea is that if I have the url myphotosite.tld/foo/bar?wut=1 it should internally redirect to index.php?__route__=/foo/bar (and NOT __route__=/foo/bar?wut=1).

The problem is: The above regex gives me the latter (i.e. WITH the part after the question mark). I tried to tweak the regex to the following expression:

^/([^?]*)\?*$

to make sure the search pattern would NOT include the ?. This, however, results in a 500 error if there IS a question mark (and normal behavior when there is none, but then the other pattern obviously also works...)

Any ideas what I'm doing wrong?

I don't understand your question, perhaps if you have me an input and an output. I use http://rubular.com/ to play around with expressions, it's ran in Ruby, but works fine with my Java code as well, never tried PHP regex in it.

green = input
blue = desired output
red = undesired (but actually obtained by this pattern) output

the regex has nothing to do with PHP, it's run by Cherokee (so C, or whatever)

so in other words I want a patter which matches the bold part of the following:

/foo/bar?wut=1

the greediness of the first group seems to be the problem. Don't know how to get rid of it though?

hm. not bad - I'll have to check if those strings can contain other characters too, but then I'll just add them...

woah, this is even better, based on your draft:

(that's the exact thing i need, sorry to throw your first part out - it wasn't wrong, just not what the server config expects

)

thanks, awesome!
