README

This is PHP implementation of Pay By Square generator. Source code is based on code of Ján Fečík (https://jan.fecik.sk/blog/qr-generator-platieb-pay-by-square-v-php/) and ported as composer package and spiced with tiny OOP.

This library not requires registration on **api.

Requirements

• PHP 7.4+
• Enabled function proc_open() on server
• Linux server
• Installed xz package on server (for LZMA compression, which is necessary for correct compression of data during generation)

Installation

composer require trinetus/pay-by-square-generator

Usage

Simply add namespace usage to your code:

use Trinetus\PayBySquareGenerator;

Initialize object, fill with invoice data and return final output string:

$outputString = (new PayBySquareGenerator())
    ->setAmount(1.25)
    ->setIban("SKxxyyyyzzzzzzzzzzzzzzzz")
    ->setBic("XXXXXXXX")
    ->setBeneficaryName("Account name")
    ->setVariableSymbol("1234567890")
    ->setConstantSymbol("0309")
    ->setSpecificSymbol("9999")
    ->setNote("Test payment")
    ->getOutput();

Use some of your favorite QR code generator for creating QR code from $outputString. This example is using bacon/bacon-qr-code (https://packagist.org/packages/bacon/bacon-qr-code)

$renderer = new ImageRenderer(
    new RendererStyle(400),
    new ImagickImageBackEnd()
);
$writer = new Writer($renderer);
$qrcode = $writer->writeString($outputString);

Simply display image in your web/pdf/email template (or do whatever you need with QR code image). This example is for Laravel's blade template:

<img src="data:image/png;base64,{{ base64_encode($qrcode) }}" alt="QR code">

Or you can also save it as image file (see docs for your QR code generator library).
