chillerlan/php-qrcode is a modern, flexible PHP library for generating QR codes. It supports various customization options such as size, encoding, error correction, and logo embedding.

New features:
- creation/editing of QR codes.
- support of images with perspective
- optional experimental offscreen hardware acceleration (via openGL 2-FBOs)
