Sending image using sockets with base 64 format by JSON - php

Question

I'm trying to send an image taken from the camera and converted to base 64 format to be converted into a JSON format. Everything is working fine except when I use the function of json.dump in python it adds \n to the image_64 base format, where in the server, it can't decode the picture properly- It's giving a blank image .
Python code to send the image :
import socket
import datetime
import json
import base64 , urllib
from cam import *
Signal = "200"
Date = datetime.datetime.now()
captureImage()
del(camera)
facechop('test_image.png')
image ='test_image.png'
image_64 = base64.encodestring(open(image,"rb").read())
print "----------------------------------------------"
try:
client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client_socket.connect(('X.X.X.X', 20001))
code = json.dumps({"number": Signal, "date" : "{:%m/%d/%Y}".format(Date), "image" : image_64}).encode('utf8')
client_socket.sendall(code)
receive = client_socket.recv(5012)
print receive
except Exception as e:
print("ERROR: "+str(e))
& the server code is :
function checkMessageRecieved(){
foreach ($this->changed as $key => $socket) {
$buffer = null;
while(socket_recv($socket, $buffer, 10240000, 0) >= 1) {
$n = trim($buffer);
$decodeJSON = json_decode($n, true);
$number = $decodeJSON['number'];
$date = $decodeJSON['date'];
$image = $decodeJSON['image'];
echo $number;
echo $date;
echo $image;
$image=str_replace("\n", "" , $image);
$img = str_replace('data:image/png;base64,', '', $image);
$img = str_replace(' ', '+', $img);
$data = base64_decode($img);
$file = __DIR__ . "/../photos/public/" . uniqid() . '.png';
$success = file_put_contents($file, $data);
print $success ? $file : 'Unable to save the file.';
$this->sendMessage(trim("Successfully done...") . PHP_EOL);
unset($this->changed[$key]);
break;
}
}
}
