Well, it looks like it follow the colon, so the correct approach would be to use explode(':', $string) and then trim() position 1 of the resulting array.
If the line is always in format
"Domain name: DOMAIN.COM",

<?php
$line = "Domain name: DOMAIN.COM";
$domain = substr($line,12);
echo"$domain";
?>

Open in new window


If not - use preg_match or post the output / script code.

<?php // RAY_temp_prowebinteractive.php
error_reporting(E_ALL);

// TEST DATA FROM THE POST AT EE
$str = "Domain name: DOMAIN.COM";

// THE DELIMITER
$dlm = ':';

// PARSE THE STRING
$arr = explode($dlm, $str);
$new = trim($arr[1]);

echo $new;

basically  of an array of values such as

$result['rawdata'][$i]

as I loop through the array I would like to search for the DOMAIN variable so I can href it
Avatar of Beverley Portlock
As long as the domain is always at the end of the line, I would use a regex to take care of any variation in the early part of the string.

while( $result = ...... etc ) {

     $domain = preg_replace('#^.+?([\.-0-9a-zA-Z]+)\s*$#', '$1', $result['rawdata'][$i] );

     $link = "<a href='http://$domain'>$domain</a>";

     ..... etc
}
whats is the $1 variable all about ?
nevermind, I got the answer to that, however, what you sent me is not bad, but I want it to match the exact domain searched for, I dont wnat it picking up domain name servers, or registration providers domain
In the pattern there is a bracketed group '#^.+?([\.-0-9a-zA-Z]+)\s*$#'  and in the replacement pattern (the second parameter) $1 represents that bracketed group.

What this statement is saying is "examine $result['rawdata'][$i] and if matches this pattern '#^.+?([\.-0-9a-zA-Z]+)\s*$#' then replace it with this '$1'."  In other words, if the pattern matches, the original data is completely replaced with the bracketed group represented by $1. So everything is removed and only the bracketed group which contains the domain data is retained.
"...I want it to match the exact domain searched for, I dont wnat it picking up domain name servers, or registration providers domain"

If you know what domain you are searching for, then why are you trying to pick that domain out? You already know what the domain is?

Sorry - but I'm confused.......
regular expression not working properly, it duplicates the first letter of the domain, and does not match for upper and or lowercase
bportlock:  as I mentioned, I want to HREF the domain in the HTML so if the person doing the search as sees that the domain is taken, can click on the search domain directly from the page

Make sense ?
So you want to replace the domain IN that string?

<?php

$test = "Domain name: DOMAIN.COM";

echo preg_replace('#^(.+?)([\.-0-9a-zA-Z]+)\s*$#', '$1<a href="http://$2">$2</a>', $test);

"...regular expression not working properly, it duplicates the first letter of the domain, and does not match for upper and or lowercase..."

Is the string you are comparing exactly similar in format to the one you gave me as an example? If the format of the string is different then the regex will not match it.
I must be really bad at explaining what I want because Im not being understood

if the domain is msn.com  I want to find msn.com in the string, however depending on the registrar it could show in lower, or upper case, so I want to find the msn.com in the string and replace by <a href="msn.com">msn.com</a>
