PHP QRCode Library
==================

[](#php-qrcode-library)

Installation
------------

[](#installation)

```
composer require ashus/phpqrcode
```

Generate a PNG file
-------------------

[](#generate-a-png-file)

```
\PHPQRCode\QRcode::png(
    text: 'Test',
    outfile: '/tmp/qrcode.png',
    level: \PHPQRCode\Constants::QR_ECLEVEL_L,
    size: 4,
    margin: 2,
);
```

The call writes a PNG QR code containing `Test` to `/tmp/qrcode.png`. Omit `outfile` to send the `Content-Type: image/png` HTTP header and PNG data directly to the output.

Get PNG data in memory
----------------------

[](#get-png-data-in-memory)

Use `pngString()` when the PNG should be returned instead of written or sent to the output:

```
$png = \PHPQRCode\QRcode::pngString(
    text: 'Test',
    level: \PHPQRCode\Constants::QR_ECLEVEL_L,
    size: 4,
    margin: 2,
);
```

`$png` contains the binary PNG data. This method does not send HTTP headers or produce output.

Error correction level
----------------------

[](#error-correction-level)

Pass one of the numeric constants from `\PHPQRCode\Constants`, for example `Constants::QR_ECLEVEL_L`. The methods also accept the strings `L`, `M`, `Q`, and `H` in either case.

Size and margin
---------------

[](#size-and-margin)

`size` is the number of pixels used for one QR-code module. It defaults to `3` and has a minimum of `1`.

`margin` is the width of the empty border around the QR code, measured in modules rather than pixels. It defaults to `4` and has a minimum of `0`.

The generated image is also constrained by `Constants::QR_PNG_MAXIMUM_SIZE` (default `1024` pixels), so a requested `size` may be reduced for large QR codes.
