A PHP QR Code generator and reader with a user-friendly API
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. The library is PSR-compliant and built for ease of use in modern PHP projects, making it suitable for generating QR codes in web apps, receipts, and authentication systems.

automatic recognition may be slow, hence the name.
New features:
- creation/editing of QR codes.
- support of images with perspective
- optional experimental offscreen hardware acceleration (via openGL 2-FBOs)
