For PHP version ... - 7.4+ use `^4.3` - 7.2+ use `^3.4.1` (v3.4.1 also supports PHP8) - 7.0+ use `^2.0` - 5.6+ use `^1.0` (please let PHP 5 die!) In case you want to keep using `v4.3.x-dev`, specify the hash of a commit to avoid running into unforseen issues like so: `v4.3.x-dev#c115f7bc51d466ccb24c544e88329804aad8c2a0` PSA: [PHP 7.0 - 7.3 are EOL](https://www.php.net/supported-versions.php) and therefore the respective `QRCode` versions are also no longer supported! Quickstart ---------- [](#quickstart) We want to encode this URI for a mobile authenticator into a QRcode image: ``` $data = 'otpauth://totp/test?secret=B3JX4VCVJDVNXNZ5&issuer=chillerlan.net'; // quick and simple: echo ''; ``` [![QR codes are awesome!](https://raw.githubusercontent.com/chillerlan/php-qrcode/v4.3.x/examples/example_image.png)](https://raw.githubusercontent.com/chillerlan/php-qrcode/v4.3.x/examples/example_image.png) [![QR codes are awesome!](https://raw.githubusercontent.com/chillerlan/php-qrcode/v4.3.x/examples/example_svg.png)](https://raw.githubusercontent.com/chillerlan/php-qrcode/v4.3.x/examples/example_svg.png) Wait, what was that? Please again, slower! Advanced usage -------------- [](#advanced-usage) Ok, step by step. First you'll need a `QRCode` instance, which can be optionally invoked with a `QROptions` (or a [`SettingsContainerInterface`](https://github.com/chillerlan/php-settings-container/blob/master/src/SettingsContainerInterface.php), respectively) object as the only parameter. ``` $options = new QROptions([ 'version' => 5, 'outputType' => QRCode::OUTPUT_MARKUP_SVG, 'eccLevel' => QRCode::ECC_L, ]); // invoke a fresh QRCode instance $qrcode = new QRCode($options); // and dump the output $qrcode->render($data); // ...with additional cache file $qrcode->render($data, '/path/to/file.svg'); ``` In case you just want the raw QR code matrix, call `QRCode::getMatrix()` - this method is also called internally from `QRCode::render()`. See also \[\[Custom output interface\]\]. ``` $matrix = $qrcode->getMatrix($data); foreach($matrix->matrix() as $y => $row){ foreach($row as $x => $module){ // get a module's value $value = $module; // or via the matrix's getter method $value = $matrix->get($x, $y); // boolean check a module if($matrix->check($x, $y)){ // if($module >> 8 > 0) // do stuff, the module is dark } else{ // do other stuff, the module is light } } } ``` Have a look [in the examples folder](https://github.com/chillerlan/php-qrcode/tree/main/examples) for some more usage examples. ### Notes [](#notes) The QR encoder, especially the subroutines for mask pattern testing, can cause high CPU load on increased matrix size. You can avoid a part of this load by choosing a fast output module, like `OUTPUT_IMAGE_*` and maybe setting the mask pattern manually (which may result in unreadable QR Codes). Oh hey and don't forget to sanitize any user input! Custom output interface ----------------------- [](#custom-output-interface) Instead of bloating your code you can simply create your own output interface by creating a `QROutputInterface` (i.e. extending `QROutputAbstract`). ``` class MyCustomOutput extends QROutputAbstract{ // inherited from QROutputAbstract protected QRMatrix $matrix; // QRMatrix protected int $moduleCount; // modules QRMatrix::size() protected QROptions $options; // MyCustomOptions or QROptions protected int $scale; // scale factor from options protected int $length; // length of the matrix ($moduleCount * $scale) // ...check/set default module values (abstract method, called by the constructor) protected function setModuleValues():void{ // $this->moduleValues = ... } // QROutputInterface::dump() public function dump(string $file = null):string{ $output = ''; for($row = 0; $row < $this->moduleCount; $row++){ for($col = 0; $col < $this->moduleCount; $col++){ $output .= (int)$this->matrix->check($col, $row); } } return $output; } } ``` For more examples, have a look at the [built-in output modules](https://github.com/chillerlan/php-qrcode/tree/main/src/Output). In case you need additional settings for your output module, just extend `QROptions`... ``` class MyCustomOptions extends QROptions{ protected string $myParam = 'defaultValue'; // ... } ``` ...or use the [`SettingsContainerInterface`](https://github.com/chillerlan/php-settings-container/blob/main/src/SettingsContainerInterface.php), which is the more flexible approach. ``` trait MyCustomOptionsTrait{ protected string $myParam = 'defaultValue'; // ... } ``` set the options: ``` $myOptions = [ 'version' => 5, 'eccLevel' => QRCode::ECC_L, 'outputType' => QRCode::OUTPUT_CUSTOM, 'outputInterface' => MyCustomOutput::class, // your custom settings 'myParam' => 'whatever value', ]; // extends QROptions $myCustomOptions = new MyCustomOptions($myOptions); // using the SettingsContainerInterface $myCustomOptions = new class($myOptions) extends SettingsContainerAbstract{ use QROptionsTrait, MyCustomOptionsTrait; }; ``` You can then call `QRCode` with the custom modules... ``` (new QRCode($myCustomOptions))->render($data); ``` ...or invoke the `QROutputInterface` manually. ``` $qrOutputInterface = new MyCustomOutput($myCustomOptions, (new QRCode($myCustomOptions))->getMatrix($data)); //dump the output, which is equivalent to QRCode::render() $qrOutputInterface->dump(); ``` ### Custom module values [](#custom-module-values) You can distinguish between different parts of the matrix, namely the several required patterns from the QR Code specification, and use them in different ways, i.e. to assign different colors for each part of the matrix (see the [image example](https://github.com/chillerlan/php-qrcode/blob/main/examples/image.php)). The dark value is the module value (light) shifted by 8 bits to the left: `$value = $M_TYPE > 8) === $M_TYPE; // for false (light) $value === $M_TYPE; ``` ...or you can perform a loose check, ignoring the module value ``` // for true ($value >> 8) > 0; // for false ($value >> 8) === 0; ``` See also `QRMatrix::set()`, `QRMatrix::check()` and [`QRMatrix` constants](#qrmatrix-constants). To map the values and properly render the modules for the given `QROutputInterface`, it's necessary to overwrite the default values: ``` $options = new QROptions; // for HTML, SVG and ImageMagick $options->moduleValues = [ // finder 1536 => '#A71111', // dark (true) 6 => '#FFBFBF', // light (false) // alignment 2560 => '#A70364', 10 => '#FFC9C9', // timing 3072 => '#98005D', 12 => '#FFB8E9', // format 3584 => '#003804', 14 => '#00FB12', // version 4096 => '#650098', 16 => '#E0B8FF', // data 1024 => '#4A6000', 4 => '#ECF9BE', // darkmodule 512 => '#080063', // separator 8 => '#AFBFBF', // quietzone 18 => '#FFFFFF', ]; // for the image output types $options->moduleValues = [ 512 => [0, 0, 0], // ... ]; // for string/text output $options->moduleValues = [ 512 => '#', // ... ]; ``` Public
