extracting data from a variable

[graziano]

Hello

I have this $domain="domain.com";

and I want get the text before domain.com , so domain ,
and I want echo on $result only first 4 caracters of domain (doma).

So if i have

$domain="test.com.br"; > echo should return test
$domain="major.net"; > echo should return majo

Anyone can be so pleasant to reply me how to do all this ?

Thank you
Graziano

Well, by your examples this code would be sufficent:

echo substr($domain,0,4);

But you probably want support for domains like http://test.com and www.test.com, right?

Thank you , no but the domain extension should not be considered .

for example me.com should return "me"
or abc.com.be should return abc .

Basically:

<?php
$num=strpos($domain,'.');
if ($num < 4)
{
    substr($domain,0,$num);
}
else
{
    substr($domain,0,4);
}

(all code untested)
