How to save image in folder ,when you convert binary image to string

Question

I have tried to convert binary data into an image format and then save this image in a folder. I am using imagesavealpha function but it is not working.

My code is below:

<?php 
$image_data=file_get_contents('Logo.png');
$encoded_image=base64_encode($image_data);
$decoded_image=base64_decode($encoded_image);
$im = imagecreatefromstring($decoded_image);

    header('Content-Type: image/png');
    imagepng($im);
    $fileName ='/image/'.date('ymdhis').'.png'; 

    imagealphablending($im,false); 

    imagesavealpha($im, true);
?>

Set the flag to save full alpha channel information (as opposed to single-color transparency) when saving PNG images — rocoder

Okay... and where in this code are you actually saving the image? Also, why are you getting the image's contents, encoding them, decoding them, and then loading them as a string? Why not just imagecreatefrompng("Logo.png")? — Niet the Dark Absol

Okay, so the first two lines are just getting data in the format that your real code will expect. Gotcha. That still doesn't explain where your "save the image" call is. — Niet the Dark Absol

use file_put_contents

$data = base64_decode($data);

file_put_contents('/tmp/image.png', $data);

or

file_put_contents('img.png', base64_decode($base64string));
