remove www from url

[wildteen88]

Try this:
[code=php:0]<?php

$string = "Here´s a ftp://mysite.com string  https://mysite.com with a link to www.somesite.com bla bla";

$string2 = preg_replace('/([a-z]+:\/\/|[a-z]+:\/\/?www.)([-a-z0-9_][-a-z0-9_\.]+\.[a-z]{2,4}(\/[-a-z0-9_\.%&+\/=&]+)?)/is', '\\2', $string);

// remove any left over instances of www.
$string2 = str_replace('www.', '', $string2);

echo $string2;

?>[/code]

ok, here's a shorter version... might achieve what you're after.

[code=php:0]
<?php
$string = "Here´s a string  https://mysite.com with a link to www.somesite.com bla bla";
echo preg_replace('/(https?:\/\/)?(www\.)?([^\s]+)/', '\\3', $string);
?>
[/code]

Also, there's another problem with your code wildteen88.. what about if my domain's http://www.ilovethewww.com ?

What's going to happen then  ;)

Here´s one that takes care of [color=blue]ftp://[/color], [color=blue]ftp.[/color], [color=blue]http://[/color], [color=blue]https://[/color] and [color=blue]www[/color]

[code=php:0]$string = "Here´s a ftp://mysite.com - ftp.mysite.com string and https://mysite.com with a
link to www.somesite.com and to http://www.anothersite.com bla bla.
Yet another link to http://mysite.com/somedir/mysite.html";

echo preg_replace('/(http(s)?:\/\/|ftp(:\/\/|\.))(www\.)?(.*?[^\s])/is', '\\5', $string);[/code]

Nicklas... why the parenthesis arount the first 's'?

You don't want to match it, and it's not being user for alternation.

Surely [color=green][tt]https?[/tt][/color] says match [color=red][tt]http[/tt][/color] and an optional [color=red][tt]s[/tt][/color]

Yeah, I know, but for some reason, the expression falls apart if I do it that way, if I put the optional [b]s[/b] in a subpattern, it works.
Anyways, here´s a small update, the previous regexp removed everything as it should, but left the [b]www[/b] untouched. this has now been fixed.

[code=php:0]$string = "Here's a ftp://mysite.com - ftp.mysite.com string and https://mysite.com with a
link to www.somesite.com and to http://www.anothersite.com bla bla.
Yet another link to http://mysite.com/somedir/mysite.html";

echo preg_replace('/((http(s)?:\/\/|ftp(:\/\/|\.)))?(www\.)?/is', '', $string);[/code]
