convert base64 to real image and save in a folder php - php

Question

I found the below php file upload from the web and it worked fine till i designed a web application in angular 4 which a photo before being upload will have to be cropped. When the image is cropped, it saves the cropped image in a base64 format, now my problem is how i can configure my current php script to convert the base64 image to a real image
if ($_SERVER['REQUEST_METHOD'] !== 'POST') {
echo json_encode(array('status' => false));
exit;
}
$path = '../myapp/img_folder/';
if (isset($_FILES['file'])) {
$originalName = $_FILES['file']['name'];
$ext = '.'.pathinfo($originalName, PATHINFO_EXTENSION);
$generatedName = md5($_FILES['file']['tmp_name']).$ext;
$filePath = $path.$generatedName;
if (!is_writable($path)) {
echo json_encode(array(
'status' => false,
'msg' => 'Destination directory not writable.'
));
exit;
}
if (move_uploaded_file($_FILES['file']['tmp_name'], $filePath)) {
echo json_encode(array(
'status' => true,
'originalName' => $originalName,
'generatedName' => $generatedName
));
}
}
else {
echo json_encode(
array('status' => false, 'msg' => 'No file uploaded.')
);
exit;
}

Here is the solution for your problem. Tested and Working Properly.
$encoded = "encoded---text---here===";
$file = fopen("mypicture.png", "w"); //(you can put jpg, png or any other extension)
fwrite($file, base64_decode($encoded));
fclose($file);
