PHP calling Python with Base64 image data fails - php

Question

I am trying to make a program for my company, that takes images and sends them to an API with relevant information.
The script takes a title, makes a directory on my system, puts the images in the directory, loops through the directory, converts each image to Base64Data, and passes the data do a python script that posts the data to the API. But for some reason, my loop stops on the first image.
UPDATED CODE: I tried to make the code a little more understandable. I am getting an invalid base64 code from the API. The function "photo" shows the format XML has to be constructed in.
UPDATED - FIX: Used cURL library in PHP instead of passing data to python script.
<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);
$count = 0;
function photo($base64, $caption, $description, $displayname, $credits){
$data = "<image xmlns='http://apiapi.com/cms' xmlns:i='http://www.w3.org/2001/XMLSchema-instance'><caption>'";
$data .= $caption;
$data .= "'</caption>";
$data .= "<credits>'";
$data .= $credits;
$data .= "'</credits><data>'";
$data .= $base64;
$data .= "'</data>";
$data .="<description>'";
$data .= $base64;
$data .= "'</description><displayname>'";
$data .= $displayname;
$data .="'</displayname><extension>JPG</extension>";
$data .= "<imageusage>SlideShow</imageusage><uploadmethod>Server</uploadmethod>";
$data .= "</image>";
return $data; }
function base64url_encode($s) {
return str_replace(array('+', '/'), array('-', '_'), base64_encode($s));
}
if ($_SERVER['REQUEST_METHOD'] == 'POST'){
$dirty_title = $_POST['title'];
$title = htmlspecialchars($dirty_title);
chdir('uploads');
mkdir($title, 0777, true);
chdir($title);
//echo getcwd();
foreach ($_FILES['files']['name'] as $i => $name) {
$type = pathinfo($name, PATHINFO_EXTENSION);
$superstring = $title . $count .".". $type;
//echo "SuperString = " . $superstring."<br />";
if (strlen($_FILES['files']['name'][$i]) > 1) {
if (move_uploaded_file($_FILES['files']['tmp_name'][$i], $superstring)) {
$count++;
}
}
}
}
function endsWith($haystack, $needle)
{
return $needle === '' || substr_compare($haystack, $needle, -strlen($needle)) === 0;
}
if (isset($_POST['submit'])){
$curdir = getcwd();
//$exiftool = exec('exiftool -all= *.jpg');
//echo "exiftool = ".$exiftool."<br />";
$dir = new DirectoryIterator($curdir);
$count = 0;
foreach ($dir as $fileinfo){
if ($dir == '.' || $dir == '..' || endsWith($fileinfo, ".jpg_original")){}
else{
$count ++;
chmod($fileinfo, 0777);
$caption = $_POST['caption'];
$description = $_POST['description'];
$displayname = $_POST['displayname'];
$credit = $_POST['credits'];
$final_info = $curdir."/".$fileinfo;
$type = pathinfo($fileinfo, PATHINFO_EXTENSION);
$data = file_get_contents($final_info);
$mybase = base64url_encode($data);
echo "Function Worked";
$photo = photo($mybase, $caption, $description, $displayname, $credit);
$file_name = "data".$count.".txt";
$file = fopen($file_name, "w");
fwrite($file, $photo);
fclose($file);
$cwd = getcwd();
echo "REAL PATH: ".realpath($cwd);
}
}
$cwd = getcwd();
$realpath = realpath($cwd);
$test =exec("/usr/bin/python /var/www/html/helper_scripts/frankAPI.py '{$realpath}'");
echo $test;
}
?>
And here is the python script that takes the file path as argument, reads the written data that the PHP script wrote, and sends it to the API. Now im getting a 500 error, and its saying the base64 encoding that Im sending isnt recognized as base64.
