php regex help

[leegold]

I'm new to PHP regex. What I am trying to match is:

http://library.dayton.town.net

Obviously it's a mysql/php field.
Then if a match I take some action.
But it's not working any help appreciated.

while ( $row = mysql_fetch_row( $result ) ) {...
....
foreach($row as $data) {
if (preg_match("/

http://library\.dayton\.town\.net/",

$data)) {
$data= 'You got a match';
}

If that's really what you want to match, don't bother with a regex... just do

if ($data == '[URL unfurl="true"]http://library.dayton.town.net')[/URL] {
  echo 'Matched...';
}

Regular expressions are for matching patterns. So for example, if you wanted to find everything which started with http: and ended with .net you could do

$pattern = '/^http:.*\.net$/';
