chillerlan / php-qrcode example snippets


$data = 'otpauth://totp/test?secret=B3JX4VCVJDVNXNZ5&issuer=chillerlan.net';

// quick and simple:
echo '<img src="'.(new QRCode)->render($data).'" alt="QR Code" />';


// it's generally a good idea to wrap the reader in a try/catch block because it WILL throw eventually
try{
	$result = (new QRCode)->readFromFile('path/to/file.png'); // -> DecoderResult

	// you can now use the result instance...
	$content = $result->data;
	$matrix  = $result->getMatrix(); // -> QRMatrix

	// ...or simply cast it to string to get the content:
	$content = (string)$result;
}
catch(Throwable $e){
	// oopsies!
}
