How to resolve 'cannot pass parameter by reference' error in PHP?

Question

Here\'s my code:

$stmt = $conn->mysqli->prepare(\'INSERT INTO photos (CaseNo, ImageName, CaptureTime, UploadTime) VALUES (?,?,?,?)\');
$stmt->bind_p         


        

Answer 1

Maybe you need to cast it to string?

...$extension, (string) $captureTime, (string) $uploadTime);
