Convert python script to php for dht22 sensor data reading - php

Question

I would convert this Python code to read DHT22 sensor data in php. I don't know python so I can't convert all functions in the php corrispondent.
The python script is from here (I add numpy library because I was an error without it)
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import socket
import numpy
TCP_ADDR = 'MYIP'
TCP_PORT = 8899
PACK_LEN = 11
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.settimeout(30)
s.connect((TCP_ADDR, TCP_PORT))
bytes_data = numpy.zeros(PACK_LEN,int)
str_data = s.recv(PACK_LEN) #this should probably have a timeout
hex_data = str_data.encode('hex')
for n in range(0,PACK_LEN): #convert to array of bytes
lower = 2*n
upper = lower + 2
bytes_data[n] = int(hex_data[lower:upper],16)
humid = (((bytes_data[6])<<8)+(bytes_data[7]))/10.0
temp = (((((bytes_data[8])&0x7F)<<8)+(bytes_data[9]))/10.0)
if int(bytes_data[8]) & 0x80: #invert temp if sign bit is set
temp = -1.0* temp
checksum = (int(sum(bytes_data[0:10])) & 0xFF)+1
if checksum == bytes_data[10]:
print "T" + str(temp) + " H" + str(humid)
else:
print "Invalid. :("

It was just a test in php
$fp = fsockopen("192.168.0.12", 8899, $errno, $errstr, 20);
if (!$fp) {
echo "$errstr ($errno)<br />\n";
} else {
fwrite($fp, "\n");
$code = fread($fp, 26);
fclose($fp);
$code = array_shift( unpack('H*', $code) );
echo $code;
}
