$byteArray = [0x71, 0x101, 0x101, 0x107, 0x115]; 
  
// Convert byte array to base64 
$base64String = base64_encode(pack('C*', ...$byteArray)); 
  
// Create a JSON structure 
$jsonData = json_encode(['data' => $base64String]); 
  
// Display the result 
echo $jsonData; 
  
?>

Output

{"data":"cQEBBxU="}
