Uploading an image sent as byte array to FTP

[MattLav]

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

Can I ask why you are converting an "image" ( a picture/photo/piece of art that is a jpg,tiff,mpg, etc. file) ) to some  kind of array in order to upload it using an ftp process?  I would think that you would do that to the image once you got it uploaded where you could write a script to do what it is you are doing.

FTP doesn't do transfers like that. Use a temporary file like your code is already doing (but remember to delete it afterwards); get the temporary file name with tempnam.

Maybe this doesn't matter to you either, but ftp has absolutely no transit/network level security.    There is a longstanding php library (phpseclib) that implements ssh/sftp https://github.com/phpseclib/phpseclib.  There are also php extensions that do the same.
