PngCoder is a single PHP class which can encode any file to PNG image and then decode it to original file.

$coder = new PngCoder();
// encode music file to image
$coder->encode('./data/music.mp3', './tmp/music.png');
// decode it
$coder->decode('./tmp/music.png', './tmp/music.mp3');

Sometimes encoded files looks mysterious, but in common case it's just a noise:

I don't know where this can be used 😟. Feel free to add your suggestions here 😉

• PHP 5.4 and later (supports PHP 7)
• php-gd

The recommended way to install PngCoder is through Composer.

# Install Composer
curl -sS https://getcomposer.org/installer | php

Next, run the Composer command to install the PngCoder:

composer.phar require nikashitsa/png-coder

After installing, you need to require Composer's autoloader:

require 'vendor/autoload.php';
