My motive is to get the hosting provider of a domain name using php. When tracert/traceroute to any domain name (yahoo.com), it gives:
traceroute to 72.30.2.43 (72.30.2.43), 30 hops max, 40 byte packets

I want to get to the last valid domain name, which is (in this case):
`10 * * te-8-1.bas-k2.sk1.yahoo.com (68.180.160.11) 41.787 ms`
I can get to this easily by using this code (stristr()):
$a = explode("\n",$str);
foreach($a as $v){
if(!stristr($v,'* * *')){
echo $v.'
';
}
}
I need this result:
yahoo.com
it should be from the # 10th (10 * * te-8-1.bas-k2.sk1.yahoo.com (68.180.160.11) 41.787 ms)
Does anyone has a solution to this? Or if someone has better solution to my basic objective here.
Would really appreciate any help.
Thank you!
//Cut the excess off.
$starPos = strpos($str,'* * *');
$subSet = substr($str,0,$starPos);
$a = explode("\n",$subSet);
$last = $a[count($a)-2] ;
//Preg match the domain
echo "RESULT: ";
if (preg_match('/\.([^\.]*?\.[^\.]*?)\s\(\d/i', $last, $regs)) {
echo $result = $regs[1];
} else {
echo $result = "";
}
