$image = new ZBarCodeImage(“1.jpg”);
$scanner = new ZBarCodeScanner();
$barcode = $scanner->scan($image);
print_r($barcode);
/* Loop through possible barcodes */
if (!empty($barcode)) {
　　foreach ($barcode as $code) {
　　　　printf(“Found type %s barcode with data %s\n”, $code[‘type’], $code[‘data’]);
