							# QRMarkupHTML

[Class `QRMarkupHTML`](https://github.com/chillerlan/php-qrcode/blob/main/src/Output/QRMarkupHTML.php): HTML output

This class is a cheap markup substitute for when SVG is not available or not an option (which was an issue before ca 2012).
As a general rule: if you plan to display the QR Code in a web browser, you should be using the [SVG output](./Built-In-Output-QRMarkupSVG.md).


## Example

See: [HTML example](https://github.com/chillerlan/php-qrcode/blob/main/examples/html.php)

Set the options:

```php
$options = new QROptions;

$options->outputType   = QROutputInterface::MARKUP_HTML;
$options->cssClass     = 'qrcode';
// default values for unassigned module types
$options->markupDark   = '#555';
$options->markupLight  = '#CCC';
$options->moduleValues = [
	// finder
	QRMatrix::M_FINDER_DARK    => '#A71111', // dark (true)
	QRMatrix::M_FINDER_DOT     => '#A71111', // finder dot, dark (true)
	QRMatrix::M_FINDER         => '#FFBFBF', // light (false)
	// alignment
	QRMatrix::M_ALIGNMENT_DARK => '#A70364',
	QRMatrix::M_ALIGNMENT      => '#FFC9C9',
];
```

Output in a HTML document (via PHP):

```php
<?php

$data = 'https://www.youtube.com/watch?v=dQw4w9WgXcQ';
$out  = (new QRCode($options))->render($data);

header('Content-type: text/html');

?>
