Attempted to call function \"imagecreatefromstring\" from namespace \"Zxing\"

[Vadim Kosolapov]

My code:
`<?php

use Zxing\QrReader;

$qrcode = new QrReader('http://qrcoder.ru/code/?lalala&4&0');
$text = $qrcode->text(); //return decoded text from QR Code
echo $text;

I have error: Attempted to call function "imagecreatefromstring" from namespace "Zxing"
`
How to fix problem?

Check if you have GD lib extension activated in PHP

Check if you have GD lib extension activated in PHP

This solved for me, uncommenting extension GD on php.ini file.
