PHP Strip string of first url and report results

Russel Peter video: <a rel="nofollow" href="http://www.youtube.com/watch?v=2bP9tRhJRTw">www.youtube.com/watch?v=2bP9tRhJRTw</a> russel peters video blah blah. Turtles: <a href="http://turtles.com">turtles.com</a>

I have a string that contains text and and tags with enclosed urls like the above example.

I want to strip the out ONLY the first tag found

<a rel="nofollow" href="http://www.youtube.com/watch?v=2bP9tRhJRTw">www.youtube.com/watch?v=2bP9tRhJRTw</a>

and from that, strip out the url inside the href="".

But... i also want to be able store the text around the tag that is pulled out.

I'm looking for something like this as the end result after all the stripping:

$originalstring = "Russel Peter video: <a rel="nofollow" href="http://www.youtube.com/watch?v=2bP9tRhJRTw">www.youtube.com/watch?v=2bP9tRhJRTw</a&开发者_如何学运维gt; russel peters video blah blah. Turtles: <a href="http://turtles.com">turtles.com</a>";


$preurl = "Russel Peter video: ";

$atag = "<a rel="nofollow" href="http://www.youtube.com/watch?v=2bP9tRhJRTw">www.youtube.com/watch?v=2bP9tRhJRTw</a>";

$url = "http://www.youtube.com/watch?v=2bP9tRhJRTw";

$afterurl = " russel peters video blah blah. Turtles: <a href="http://turtles.com">turtles.com</a>";

THANK YOU FOR YOUR HELP

NOTE: i apologize if I've used the wrong terms.

$orgstring = 'Russel Peter video: <a rel="nofollow" href="http://www.youtube.com/watch?v=2bP9tRhJRTw">www.youtube.com/watch?v=2bP9tRhJRTw</a> russel peters video blah blah. Turtles: <a href="http://turtles.com">turtles.com</a>';
$s = explode(":",$orgstring,2);
$preurl = $s[0];
$href= explode('href="',$s[1]);
$url=preg_replace("/\">.*/","",$href[1]);
$atag = preg_replace("/\">.*/","",$s[1]);
$after=explode("</a>",$orgstring,2);
$afterurl=$after[1];
print "\$preurl: $preurl\n";
print "\$url: $url\n";
print "\$atag: $atag\n";
print "\$afterurl: $afterurl\n";

output

$ php test.php
$preurl: Russel Peter video
$url: http://www.youtube.com/watch?v=2bP9tRhJRTw
$atag:  <a rel="nofollow" href="http://www.youtube.com/watch?v=2bP9tRhJRTw
$afterurl:  russel peters video blah blah. Turtles: <a href="http://turtles.com">turtles.com</a>

You can use explode($tags, ' ', 2); to get an array of two elements, the first being the first tag (the URL) and the second being all the other tags, if you know for sure they're always going to be space-separated.
