<?phpfunction get_page_content($url){ $url = eregi_replace('^http://', '', $url); $temp = explode('/', $url); $host = array_shift($temp); $path = '/'.implode('/', $temp); $temp = explode(':', $host); $host = $temp[0]; $port = isset($temp[1]) ? $temp[1] : 80; $fp = @fsockopen($host, $port, &$errno, &$errstr, 30); if ($fp){     @fputs($fp, "GET ".$path."
