preg_replace help needed

[phplearner]

I have this so far:

<?php
$pattern = "xrc.pqmt.somedomain.com";
$pattern = preg_replace("/.*(\w*\.\w*)$/i", "$1", $pattern); // need only:  somedomain.com (or some-domain.com if hyphenated)
echo $pattern;
?>

But all I am getting is: .com

What I need is: somedomain.com

Or, if it is a hyphenated one: some-domain.com

Umh, of course, things like: my258.com or: my-258.com, etc.

Thanks much.

(EDIT🙂 Darn...the blackslashes won't show in the post.

I'll try it this way:

<?php
$pattern = "xrc.pqmt.somedomain.com";
$pattern = preg_replace("/.(\w.\w*)$/i", "$1", $pattern); // need only: somedomain.com (or some-domain.com if hyphenated)
echo $pattern;
?>

OK...I just got this to work for a non-hyphenated situation:

$pattern = preg_replace("/..([\w].\w*)$/i", "$1", $pattern);

This yields 'somedomain.com

But if I try 'some-domain.com' it yields the whole string.

AHHH....

This works!

<?php
$pattern = "xrc.pqmt.some33-domain55.com";
$pattern = preg_replace("/..([\w-].\w)$/i", "$1", $pattern); // need only: somedomain.com (or some-domain.com if hyphenated)
echo $pattern;
?>

Umh, it's times like these I wish I would* have kept up with my Perl studies years ago 🆒

Hope someone else can use this for something.
