[SOLVED] Reg Exp for google keywords

[darkdmr]

About my site:
Google finds it by some keywords. I want to make a php script to get the keyword by the GOOGLE URL.
For example

http://www.google.bg/search?q=sportingbet+info&start=0&ie=utf-8&oe=utf-8&client=firefox-a&rls=org.mozilla:en-US:official

I see it found me by the keyword "Sportingbet info".
I try it that way :
preg_match_all ('/q=(.+)&/', $url, $matches)

but in matches it returns :

q=sportingbet+info&start=0&ie=utf-8&oe=utf-8&client=firefox-a&rls=org.mozilla:en-US:official

How to make it return

q=sportingbet+info

10x.

I solved it by replacing (.+) with (.+?)
