rewrite problem with multiple parameters

[Guest]

Hi!

Beginner-Question:
I want to rewrite www.myserver.com/XXX/YYY/
to
www.myserver.com/page.php?var1=XXX&var2=YYY

Please, help: How can I make it????

RewriteEngine On
RewriteBase /
RewriteRule ^(.*?)/(.*?)/$ /page.php?var1=$1&var2=$2

I think that will do it...

you don't need the ? in the (.*).

. = any one character
*= match previous character 0-infinite times
?= match previous character 1 time.

just a simple (.*) is all it needs

[Samuraid]

but for regular expressions the "?" forces the matching to not be greedy. And it would probably be necessary to keep the RewriteRule from matching:
www.myserver.com/XXX/YYY/ZZZ/

with $1 = "XXX/YYY" and $2 = "ZZZ"

It's just a normal rule of regular expressions...
It might be different for mod_rewrite, but I know with normal regular expressions, you would want the .*? instead of .*

[seomike]

that's why you use conditions and end the rules with a $. I'll admit I'm not a pro at regular expressions but mod rewrite is limited even though it follow the perl regular expression model.

[Samuraid]

Even if you use the $ on the end, it will still match greedily.

If you match /(.*)/(.*)/$ you are in danger of having RegEx match /(XXX/YYY)/(ZZZ)/$

But if you use .*? it forces the matching to look for the next "/" instead of trying to match as much as possible.

At least this is how it works with perl regular expressions and php preg_ functions as well.
