[SOLVED] Stripping a Domain

[.Darkman]

Hi,

 

I need a small help.

How to strip a domain name alone from an URL.

 

For eg, User enters http://www.phpfreaks.com/forums/index.php?action=post;board=1.0 in a field.

I need that to be converted into http://www.phpfreaks.com/

 

How do i do it ?

 

Also how do i make so that http://phpfreaks.com/ is converted into http://www.phpfreaks.com/

 

 

Thanks,

you need to look into split(), str_replace, and strpos().

 

you will always get use out of regex.

You might want to use parse_url().  It's much less effort.

Thanks a lot for this.

Now how do i convert phpfreaks.com to www.phpfreaks.com

$str = 'phpfreaks.com';
if (strpos($str, 'www') !== 0) {
  # !== 0 fails only if 'www' is found at the start of $str
  $str = "www.$str";
}

 

I deliberately searched for 'www' instead of 'www.', to allow for cases like www1, www2.  I often use a regex like this instead

 

if (!preg_match('|www[0-9]*\.|', $str))

 

That one matches

 

www.

www1.

www50.

 

And all other numbers following www
