string from a string

[denoteone]

having a hard time getting data out of a string saved in a variable.

 

$fp = "[Querying whois.arin.net] [Reirected to whois.ripe.net:43] [Querying whois.ripe.net]";

I need to create a new variable that only has the string "whois.ripe.net"   the second instance of it above.

$newfp = getstr($fp, get the data between the 2nd instance of Querying and the 3rd instance of ]);

echo $newfp;

output   whois.ripe.net

$fp = "[Querying whois.arin.net] [Redirected to whois.ripe.net:43] [Querying whois.ripe.net]";

preg_match_all('~\[Redirected to ([^:]*):~i',$fp,$matches);

echo $matches[1][0];

$fp = "[Querying whois.arin.net] [Redirected to whois.ripe.net:43] [Querying whois.ripe.net]";
$a = preg_split("/Querying/",$fp);
print end($a);
