[qwe010]

hello

how i can Extracting the domain

from link like that

http://www.phpbuilder.com/board/
and
http://sub.phpbuilder.com/board/

i try with strstr

if ( strstr($site, "www") ){

$ilk = strpos($site, ".");
$orta = substr($site, $ilk+1);
$ilkson = strpos($orta, "/");
$orta = substr($site, $ilk+1, $ilkson+1);

$uzunluk = strlen($orta);
$son = substr($orta, $uzunluk-1);

if ($son == "/"){
$ss = substr($orta, 0, $uzunluk-1);
} else {
$ss = $orta;
}

But not work Correctly

Especially with the short domain

any idea ?

Do you want the sub-domain portion, too, or just the domain? If the latter, it get's a little tricky with some of the 3-part domains, like "amzon.co.uk".

Anyway, I might approach it with preg_match, something like:

preg_match('#https?://([^/]+)(/|\s|$)#i', $string, $matches);
$domain = $matches[1];

Yes this what i mean

preg_match('#https?://([^/]+)(/|\s|$)#i', $string, $matches);
$domain = $matches[1];

Excellent Working good

But not work with ftp ?

[NogDog]

To include FTP, change the regexp to:

'#(f|ht)tps?://([^/]+)(/|\s|$)#i'

Then use $matches[2] (instead of $matches[1]).
