How to save a PNG image server-side, from a base64 data string

Question

I\'m using Nihilogic\'s \"Canvas2Image\" JavaScript tool to convert canvas drawings to PNG images. What I need now is to turn those base64 strings that this tool generates,

Answer 1

try this...

$file = $_POST['file']; //your data in base64 'data:image/png....';
$img = str_replace('data:image/png;base64,', '', $file);
file_put_contents('img/imag.png', base64_decode($img));
