Exception Handling

← Back to index

All exceptions extend the base QRCodeException (itself extending RuntimeException), so you can catch broadly or narrowly.

Exception	Thrown when
GenerationException	QR code generation fails
DecodingException	No QR code detected, or decoding fails
InvalidSourceException	The input source is missing, unreadable, or unsupported
UnsupportedFormatException	Requested output/input format isn’t supported by the environment

use Aicrion\QRCode\Exceptions\QRCodeException;

try {
    $result = $qr->readFromPath('/missing/file.png');
} catch (QRCodeException $e) {
    // handles InvalidSourceException, DecodingException, etc.
    logger()->error($e->getMessage());
}
