## What it is
A PHP library for generating Model 2 QR Codes (versions 1-40, all ECC levels, mixed encoding modes) with extensible output modules for raster and vector formats. It also includes a QR Code reader/decoder based on a PHP port of the ZXing library.

## Use cases
- generate qr codes in php
- create qr code as png or svg image
- decode a qr code from an image in php
- generate qr codes with kanji or chinese text
- add qr code generation to a web app
- scan and read qr code content server-side

## When to choose
- you need QR generation and/or decoding in a PHP project
- you need flexible output formats (PNG, SVG, JPEG, WebP, etc.)
- you need multi-byte encoding modes like kanji or hanzi
- you want a well-maintained library with PHP 7/8 support

## When to avoid
- you need QR generation in a non-PHP stack
- you need other barcode symbologies beyond QR codes
- you need extremely high-throughput real-time decoding

## Facets
- artifact type: library
- maturity: active
- function: image-processing, parser, sdk
- domain: web-development, image-processing, developer-tools
- platform: php, cli
- tags: qr-code, qrcode-generator, qrcode-reader, svg-output, gdimage, imagemagick, zxing-port, barcode, web-server
