[Uploading an image sent as byte array to FTP]

Hi all,

I'm trying to upload an image to an FTP after sending it as a byte array. 

I am sending the image from UE4 using REST:

but I have no understanding of PHP so am struggling with processing the image to in-turn upload it.

I have tried searching the forums and the results I have found seem to be defining the path to a local image and uploading that directly, but in this case I don't have a path to an image, just the byte array.
Because I have such little understanding of PHP, i'm struggling to discover how to access the actual data being sent and therefore even debug if it is sent correctly.

 

<?php
 $ftp_server="1.1.1.1";
 $ftp_user_name="username";
 $ftp_user_pass='password123';
 $remote_file = "/uploads/temp.jpg";

//my attempt at converting the byte array to an image
 $binary=base64_decode($base);

 // set up basic connection
 $conn_id = ftp_connect($ftp_server);

 // login with username and password
 $login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
 
file_put_contents($filePath, $binary);

 // upload a file
 if (ftp_put($conn_id, $remote_file, $filePath, FTP_ASCII)) {
    echo "successfully uploaded $file\n";
    exit;
 } else {
    echo "There was a problem while uploading $fileName\n";
    exit;
    }
 // close the connection
 ftp_close($conn_id);
?>

 

Any help would be much appreciated,

 

Thanks,

 

Matt
