whats wrong with..?

[RobinTibbs]

function detectDotNet() {
    $agentstring = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.1.4322; .NET CLR 2.0.50215)";
    preg_match_all("%(.NET CLR)[ ]([0-9.]+)%", $agentstring, $matches);
    echo $matches;    
}

 

trying to grab the number after the .NET CLR, but nothing is being captured, hohum!

Nothing, but you can make a few improvements:

 

- A period outside of a character class is a metacharacter; escape it to match a literal: \.

- You can use a lookbehind since you don't need the ".NET CLR " string (and it is fixed length).
