// Specify the path to the zxing command line tool
$zxingPath = '/path/to/zxing/zxing';

// Function to perform QR Code scanning
function scanQRCode($imagePath) {
    global $zxingPath;

    // Execute zxing command and capture the output
    $output = shell_exec("$zxingPath -cp $imagePath");

    // Extract the QR Code content from the output
    preg_match('/Found ([0-9]+) barcode/', $output, $matches);
    $barcodeCount = intval($matches[1]);
    
    if ($barcodeCount > 0) {
        preg_match('/Raw text: (.*)/', $output, $matches);
        $qrCodeContent = $matches[1];
        return $qrCodeContent;
    } else {
        return null;
