What AI says about PHP QR Code

PHP QR Code is an open-source PHP library for generating QR codes and other 2D barcodes, built on the libqrencode C library and outputting PNG or JPEG images via GD2. Implemented purely in PHP with no external dependencies besides GD2, it supports QR Code versions 1–40 and encodings including numeric, alphanumeric, 8-bit, and Kanji, and can export results as images or as a bit-table, with easy TCPDF integration. The project offers API documentation, a one-file deployment merge tool, data caching, debugging, benchmarking, more than 30 examples, and is licensed under the LGPL.
