For some reason it wont do a preg replace on it

 

so any url that is like

 

http://www.youtube.com/watch?v=Smeyf8nhM5Q

 

will be preg_replace with $replacement

 

for some reason it doesnt do the preg_replace

 

this is what i have now!!

 

$url = "http://www.youtube.com/watch?v=Smeyf8nhM5Q";

			$linkpattern = "%http://(?:\S+\.swf\b|\S+?youtube\S+)%";
			$linkmatch = preg_match_all($linkpattern, $url, $linkmatches);
			$b = 0;	
			print_r($linkmatches);
				foreach($linkmatches[0] as $linkurl) {	
					$replacement = "THISISYOUTUBELINK";	
					$url = preg_replace("@$linkurl@", $replacement, $url, 1);
					$b++;
				}

echo $url;

Why are you matching something to replace it?

<?php
$url = "http://www.youtube.com/watch?v=Smeyf8nhM5Q";
echo preg_replace('%http://(?:\S+\.swf\b|\S+?youtube\S+)%', 'THISISYOUTUBELINK', $url);
?>
