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

https://www.reddit.com/r/laravel/comments/39wclp/how_to_convert_an_base64_image_string_to_an_image/

This code below should work.

$image = base64_decode(Input::get('image_cropped'));
$image_name= 'file_name.png';
$path = public_path() . "/images/" . $image_name;
file_put_contents($path, $image);

Show us an example of a base64 encoded PNG image that fails. Also `unserialize()` doesn't decode base64 encoded strings. — gre_gor, Apr 22 '16 at 15:13
this error is not related to your image creation. you write something to session store. its laravel framework session store handler related. — di3, Apr 22 '16 at 15:18
Are you coding the image from a canvas or something like that? — Jose Rojas, Apr 22 '16 at 17:12

If you inspect the form sent from request the image encoded starts with data:image/png;base64, so try with:

$img = explode(',', Input::get('image_cropped'));
$img_name = 'file_name.png';
file_put_contents(public_path().'/images/'.$img_name, base64_decode($img[1]));

This worked for me.
