Find url but not if it's in a sentance

[ebolt007]

I'm trying to write a piece that checks to see if something someone posts is a url or if it's just a url in a sentence.

Basically, I want it so if someone puts in

 

www.phpfreaks.com (then it does something)

 

but if they put

 

I am on www.phpfreaks.com where are you? (Then it does something else)

 

Like the first one will get the dom of the page and post that, and the second one would just post the sentence with the url in it as a link.

 

So I am getting my post

$Post

checking if there is a www or .com or .net or .gov in it

                                        $find2 = 'www.';

                                    $find3 = '.com';

                                    $find4 = '.net';

                                    $find5 = '.gov';

if((strstr($Post, $find2) ==true)||(strstr($Post, $find3) ==true)||(strstr($Post, $find4) ==true)||(strstr($Post, $find5) ==true)){

 

then do I explode the whole thing, or what would I do in here with the $Post? some people might put in just phpfreaks.com others might put in http://www.phpfreaks.com and others might put in http://www.phpfreaks.com/forums/index.php?action=post;board=1.0 so I need to find the www. and or .com and find the first space before that, and after that and cut out the middle section, but I'm at a loss.

 

}

You need to find it using preg_match, You can use the multi-line modifier to get URL's that are on a line by themselves, ignoring URL's that are on lines consisting of other characters.
