Code
The first test, "preg_match()", was:
if (preg_match('~http://([^\./]+\.[^/]+?)/~', $GLOBALS['dummy'], $match) != 0)
$GLOBALS['dummy2'] = $match[1];
The second test, "strpos()", was:
$pos_start = strpos($GLOBALS['dummy'], 'http://') + strlen('http://');
$pos_slash = strpos($GLOBALS['dummy'], '/', $pos_start + 2);
$pos_dot = strpos($GLOBALS['dummy'], '.', $pos_start + 1);
if ($pos_dot !== null && $pos_dot < $pos_slash)
$GLOBALS['dummy2'] = substr($GLOBALS['dummy'], $pos_start, $pos_slash - $pos_start);
