Not really an answer to your question; but consider using explode() (php.net/manual/en/function.explode.php) — user254875486

I don't understand what you're trying to achieve. You're trying to get the first part of text that is an URL (eg. prefixed with http://)? Does the http:// have to be part of the resulting match? Because as of now, your match would be ://someurlhere.com. — bummzack

Make the .* ungreedy : .*?

\bhttp(.*?)\|\b

If you want to match only after the first | do:

\|http://(.*?)\|

with this, the url is in $1

No need for regex. I see you tagged it PHP.

$boom = explode('|', 'http://someurlhere.com|sometexturl.com|sometexthere');
$url = $boom[0];
echo $url;

Output:

http://someurlhere.com
