I have a base64 encoded png, how do I write the image to a file in PHP?

Question

What\'s the proper way in PHP to create an image file (PNG), when I have the base64 encoding?

I\'ve been playing around with:

file_put_contents(\'/

You need to use base64_decode(). AND. Sometimes it is not sufficient. Here is all code that you need:

$img = $_POST['data'];
$img = str_replace('data:image/png;base64,', '', $img);
$img = str_replace(' ', '+', $img);
$fileData = base64_decode($img);
//saving
$fileName = 'photo.png';
file_put_contents($fileName, $fileData);

P.S. I used this code to get PNG image from html canvas.
