$ php8.1 -f my-php-qrcode-reader.php 
PHP Fatal error:  Uncaught Error: Call to undefined function Zxing\imagecreatefromstring() in /home/user/Development/my-php-qrcode-reader/vendor/khanamiryan/qrcode-detector-decoder/lib/QrReader.php:46

why this error occurs? did I forget something?

with that simple code:

<?php
require __DIR__ . "/vendor/autoload.php";
use Zxing\QrReader;
$qrcode = new QrReader('IMG-0069.jpg');
$text = $qrcode->text(); //return decoded text from QR Code
?>

i have executed that in the project directory:

composer require khanamiryan/qrcode-detector-decoder

okay, i have now installed the apt package php8.1-gd, now

ok, mbstring seems missing

commented

with installing apt package php8.1-mbstring all works :D

php8.1-gd was too required

commented

It says GD is required in the Readme.MD - can you close this please?

commented

no, php-gd AND php-mbstring is required. mbstring is not mentioned
