Domain filter problem

[asantos]

If i have this
$test = 'subdomain.some-other-subdomain.mydomain.com';
or
$test = 'subdomain.mydomain.com';
or
$test = 'mydomain.com';

it must return
'mydomain.com';

Any ideas? Thanks.

Try this function:

$url_info = parse_url($url);

that wont work because

$url = "http://somesubdomain.someotherstuff.abc.com/somedir";
$data = parse_url($url);
echo $data['host'];

will print:
somesubdomain.someotherstuff.abc.com

Try my new function:

<?php
$url = "http://somesubdomain.someotherstuff.abc.com/somedir";
$data = parse_domainname($url);
print_r($data);
function parse_domainname($url)
{
if (preg_match('#([a-z]+)://(.*?)\.(.*?)\.(.*?)\.([a-z]+)#is', $url, $data))
{
// http://a.b.domain.com /path
return $data;
}
else if (preg_match('#([a-z]+)://(www\.)?(.*?)\.(.*?)\.([a-z]+)#is', $url, $data))
{
// http://a.domaim.com /path
// http://www.a.domain.com /path
return $data;
}
else if (preg_match('#([a-z]+)://(www\.)?(.*?)\.([a-z]+)#is', $url, $data))
{
// http://domain.com /path
// http://www.domain.com /path
return $data;
}
}
?>

that doesnt seem to work.

the point is, i do not know the value of mydomain.

I tested it with all the combinations in your example.

Which is your result of the array, returned by the function?

The preg_match in the function removes the string after tld (.com)

* My returned array is:

Array ( [0] => [somesubdomain.someotherstuff.abc.com...] => http [2] => somesubdomain [3] => someotherstuff [4] => abc [5] => com )

Psychopsia,
actually i accomplished to solve my problem with this other simpler function:

$url = parse_url('http://subdomain.somehost.com');
$url = explode('.',$url['host']);
if(count($url)>1) {
$url = $url[count($url)-2];
} else {
$url = $url[0];
}
echo $url; //this prints "somehost"

It works with in all cases, even in "localhost"
