Hi all,
I am trying to make up a regular expression.

The purpose of this regular expression will be to scan text and look out for any URL that looks like -

Code:

www.abc.com
abc.com
http://abc.com
http://www.abc.com

and put anchor tags in against these URLs.

The text block can be any long.

Please, any help will be greatly appreciated.

I think this ought to do it:

(http://)*(www\.)*abc.com

PHP Code:

// List the file as a link, so it can easily be viewed and checked

echo "<a href=\"$url\" target=\"_blank\">$url</a><br />\n";





 // This is used to extract all the references from src, href, url, action, and window.opens

$ref=run_preg($text,"/(?:(?:src|href|url|action|window.open|popup)+\s*[=\(]+\s*[\"'`]*)([\+\w:?=@&\/#._;-]+)(?:[\s\"'`])/i");



function run_preg($text,$pattern)

{

   // Handles the preg for the scan

   preg_match_all ($pattern, $text, $matches);



   return (is_array($matches)) ? $matches[1]:FALSE;

} 

These are extracts out of robots.spider (http://robots-wizard.com/robots.spider/), download the code at http://robots-wizard.com/robots.spider.tar.gz.

Thanx for posting, guys.

While using the method provided by End User of, I devised the following function

PHP Code:

preg_replace('/(http:\/\/)*(www\.)*[a-zA-Z0-9]+\.[a-zA-Z]{3,4}/', '<a href="index.php">http://$2$3$4</a>',html_entity_decode($newContent)) 

But the problem still persists, I am not able to catch the string that was replaced. $& doesn't catch either.
