$info = array(0x33, 0x30, 0x35, 0x30, 0x30, 0x31, 0x35, 0x30, 0x2e, 0x36, 0x36);
for ($i = 0; $i < sizeof($info) / 2; $i++) {
	$msg = pack("nvc*", $info[$i * 2], isset($info[$i * 2 + 1]) ? $info[$i * 2 + 1] : '');
	echo trim($msg);
}

# output: 30500150.66

OR

$info = array(0x33, 0x30, 0x35, 0x30, 0x30, 0x31, 0x35, 0x30, 0x2e, 0x36, 0x36);
foreach ($info as $k => $v) {
