Reading QR Codes

← Back to index

The QRCodeReader class implements ReaderInterface and supports decoding from six source types.

Method	Source Type
readFromPath(string $path)	Local file path
readFromBinary(string $binary)	Raw binary image string
readFromBase64(string $base64)	Base64 / data URI string
readFromUrl(string $url)	Remote HTTP(S) URL
readFromResource($resource)	PHP stream resource
readFromGdImage(\GdImage $image)	In-memory GD image

$result = $qr->readFromPath('/path/to/qrcode.png');

echo $result->content;   // decoded string
print_r($result->points); // corner detection points

Auto-Detection

Use the facade’s generic read() method when the source type is dynamic — it inspects the value and routes to the correct reader method automatically.

$result = $qr->read($anySupportedSource);

The DecodedResult Object

DecodedResult is an immutable value object exposing:

• content: string — the decoded text
• points: array — detected marker coordinates
• format: ?string — detected barcode format (currently always QR_CODE)
• isEmpty(): bool and toArray(): array helper methods
