QUESTION
I'm using this package: https://github.com/RobThree/TwoFactorAuth and I'm trying to follow the part of the guide where you can use your own QR code provider.
I downloaded the phpqrcode.php file and placed it in the directory where TwoFactorAuth.php is located.
When require_once is at the top like in the guide, I get the error:
Fatal error: Namespace declaration statement has to be the very first statement or after any declare call in the script in /var/www/public/vendor/robthree/twofactorauth/lib/Providers/Qr/MyProvider.php on line 4
So, in the directory with TwoFactorAuth.php I added myprovider.php with the following code:

QUESTION
I would like to download a server image using PHP. Specifications:
- I do not want to use javascript and I do not want to pass the name by database and then retrieve it.
- The image I want to download is a QR code that I generated and saved in a "php_action / temp" directory. Within this directory there are several images, so I am trying to download only the file I have generated.
I added the phpqrcode library and created a file that calls this library to generate the QR code. This file is show_product2.php in root.
I am not able to get download the file.

I'm generating a QR code vCard using PHP QR Code (http://phpqrcode.sourceforge.net). It works, but not with Brazillian Portuguese characters. I can't find how to force UTF-8 to it.
The problem is that iOS will not recognize the characters, check the screenshots below (iOS and Android).
...ANSWER
Answered 2018-Nov-07 at 23:15I don't think the QR-Code is doing something wrong. The Smartphone App is reading, whatever the QR-Code contains.
The Android-App might apply a little more logic afterwards, including some encoding detection, but the QRs content is the same.
So, try to encode your data BEFORE generating the QR-Code:

QUESTION
This is weird, the first line of the following code (TCPDF - PDF creating code) works but sometimes does NOT work for no apparent reason. I hate intermittent errors. When it fails the error message is the same as line 3 shown below.
The second line works fine. I believe this is the better way to code it, not sure why though.
The third line does NOT work but I think would be more stable if it did.
The error says:
Warning: imagecreatefrompng(/var/www/vhosts/path-to-file/tcpdf/../../path/includes/php/phpqrcode.php?text=textforqrcode): failed to open stream: No such file or directory.
The ../../ is used to get to the correct directory, I know this is correct as it's the same as for line 2, includes and images are on the same level in the directory structure.
The thing is the path is correct. I guess this doesn't work because it's a file produced by a php file but this does work on line 1 where it's produced as a kind of http object.
Here's the code I've tried so far:
...ANSWER
Answered 2018-Jan-28 at 12:27You can't refer to a local file with query string parameters. If phpqrcode.php expects the text param to come from a GET param, you'll have to load it through the server. If you refer to the file directly, it will not run the PHP code but give you the PHP file instead directly. And in this case, it can't even find the file because it's looking for a file called phpqrcode.php?text=asd, not phpqrcode.php.
As far as I can see, the first way is the correct one, but if you're having problems with it then we need to know what library are you using to generate the QR code.
