I have a PHP code for sending OTP, When i execute it in my local server its works well. But when i run this code after changing it from my local to server by changing host name etc, i am getting 500 internal server error. I don't know where i am going wrong. Any solution will be apreciated. Thank you
<?php
include './include/DbHandler.php';
$db = new DbHandler();
$response = array();
// echo $_POST['mobile'];
if (isset($_POST['mobile']) && $_POST['mobile'] != '') {
$name = $_POST['name'];
$email = $_POST['email'];
$mobile = $_POST['mobile'];
$otp = rand(100000, 999999);
$res = $db->createUser($name, $email, $mobile, $otp);
if ($res == USER_CREATED_SUCCESSFULLY) {
// send sms
sendSms($mobile, $otp);
$response["error"] = false;

I dont think the 500 error comes from your code. That's likely an Apache config related problem. Possibly a stray .htaccess or php.ini got uploaded, or is syntactically wrong for the version of Apache you have on the server.
