尝试更换行
$result = mysqli_query($con,"INSERT into test (phone_no,reason,from_date,to_date,sem) values('$username','$reason','$from','$to','$sem')");
带
$result = mysqli_query($con,"INSERT into test (phone_no,reason,from_date,to_date,sem) values('$username','$reason','$from','$to','$sem')") or die("MYSQLi Error::".mysqli_error($con));
