[SOLVED] preg_match

[AtomicRax]

Ok, preg_match has me sooo confused...  ???

 

I am working on a program that logs where visitors are coming from... Such as a website or search engine... Now, I have the common URLs for the more common search engines... And I want to see if the url is contains the basic address, to know what search engine it was... I just don't know how to fill in the preg_match statement correctly... Actually, I've come back to this project after a few hours of not working on it, and am now lost in where I was going.... But here's what I had...

 

// $ref is the referring url
switch(preg_match('SOMETHING', $ref)) {
case "http://www.google.com/search":
$line = "Google";
$found = 1;
break;
case "http://search.msn.com/results.aspx":
$line = "MSN";
$found = 1;
break;
case "http://search.yahoo.com/search":
$line = "Yahoo";
$found = 1;
break;
case "http://search.live.com/results.aspx":
$line = "Windows Live";
$found = 1;
break;
}
// If no match
if($found != 1) {
echo "Not Found";
}

 

Like I said, no clue what I was thinking... but do you get the idea I have? Can you help? I'm lost...

<?php

// $ref is the referring url
preg_match('|^http://(.*?)/|i', $ref, $match);
switch($match[1]) {
case "www.google.com":
	$line = "Google";
	break;
case "search.msn.com":
	$line = "MSN";
	break;
case "search.yahoo.com":
	$line = "Yahoo";
	break;
case "search.live.com":
	$line = "Windows Live";
	break;
default:
	echo "Not Found";
}

?>

 

 

 

(If you're storing these values in a database, you can also group and count by the first N characters of the string.)

Thanks! That worked!

 

Now I have one more issue.... I have the entire URL, such as:

http://www.google.com/search?client=firefox-a&rls=org.mozilla%3Aen-US%3Aofficial&channel=s&hl=en&q=SEARCH_STRING&btnG=Google%20Search

 

What is the easiest way to just get what q equals (the string searched for to find the site)?

 

My way would be to split it at the & and then at the = and find the q and see what it equals... but there has to be an easier way...

Add to the end

 

if (preg_match('/q=(.*?)&/i', $ref, $regs)) {
$search= $regs[0];
}
