// get host name from URL
preg_match("/^(http:\/\/)?([^\/]+)/i", "http://chezmoi.aol.ca/beitaqu/now322836.html", $matches);
$host = $matches[2];
// get last two segments of host name
preg_match("/[^\.\/]+\.[^\.\/]+$/", $host, $matches);
echo "domain name is: {$matches[0]}\n";


//The above works fine. It appears the when I give preg_match a direct source for the pattern to match it works, but giving it an //array doesn't work as show below:


// get host name from URL
preg_match("/^(http:\/\/)?([^\/]+)/i", $linkarray[1][$i], $matches);
$host = $matches[2];
// get last two segments of host name
preg_match("/[^\.\/]+\.[^\.\/]+$/", $host, $matches);
echo "domain name is: {$matches[0]}\n";

//This doesn't give a result.
