Answer 1

The best way to do this is to write your base64 to a separated file so that no encoding is needed .. I have slightly altered your code to reflect this.

PHP FILE

<?php
$img = file_get_contents("image.jpg");
$data = base64_encode($img);
$content = $data;
$file = "myFile.base64";
$fp = fopen($file,"wb");
fwrite($fp,$content);
fclose($fp);

$output = shell_exec("python hello.py $file");
echo $output;
?>

PYTHON FILE

import sys
import base64
file=sys.argv[1]
f = open(file)
base_64 = f.read()

# print (base_64)
# Do what you want with the base_64 variable.

image_64_encode=base_64
with open("image.jpg","wb") as fh:
   fh.write(base64.decodebytes(image_64_encode))
