php-qrcode examples
Important: Please use the examples from the branch that matches your installed php-qrcode version ( v4.x, v5.x, dev-main )!
Simple examples that demonstrate the different output types
- image: Raster images via the GD extension
- ImageMagick: Raster Images via ImageMagick
- SVG: Scalable Vector Graphics
- HTML: HTML markup
- FPDF: PDF output, see http://www.fpdf.org/
- EPS: Encapsulated PostScript
- String: String output
- XML: XML output (rendered as SVG via an XSLT style)
- intervention/image: alternative GD/ImageMagick output, see https://image.intervention.io/
- Custom output: a simple example that demonstrates the usage of custom output classes
- Multi mode: a demostration of multi mode usage
- Reflectance: demonstrates reflectance reversal
- QRCode reader: a simple reader example
Advanced output examples
- GD Image with logo: a logo on top of the QR Code
- GD image with text: description text under the QR Code (#35)
- GD Image with rounded modules: similar to the SVG "melted" modules example (#215)
- ImageMagick with logo: a logo on top of the QR Code
- ImageMagick with image as background: an image as full size background of the QR Code
- SVG with logo: an SVG QR Code with embedded logo (that is also SVG)
- SVG with "melted" modules: an effect where the matrix appears to be like melted wax (#127)
- SVG with module group shape: this example works very similar to the "melted" modules, but creates a different effect (#233)
- SVG with randomly colored modules: a visual effect using multiple colors for the matrix modules (#136)
- SVG with a round shape and randomly filled quiet zone: example similar to the QR Codes of a certain vendor (#137)
- SVG with logo, custom module shapes and custom finder patterns: module- and finder pattern customization (#150)
- SVG with "jittering" modules: square modules randomly tilted to a certain degree to create a mosaic effect
Other examples
- Authenticator: create a QR Code that displays an URI for a mobile authenticator (featuring
chillerlan/php-authenticator) - Interactive output: interactive demo (via index.html)
- Custom module shapes: SVG paths to customize the module shapes (#150)
- ImageMagick SVG to raster conversion: uses ImageMagick to convert SVG output to a raster image, e.g. PNG (#216)
- HTML canvas SVG to PNG conversion: converts an SVG element or a data URI fom and image element to a PNG image via the HTML canvas element, includes a javascript class which handles the conversion.
Please note that the examples are self-contained, meaning that all custom classes are defined in an example file, so they don't necessarily respect the PSR-4 one file = one class principle.
