In php fnding error
$Email =$_POST[“Email”];
$query = "SELECT * FROM userinfo WHERE RandomID=‘$rand’ ";
$result = mysqli_query($conn,$query);
$count = mysqli_num_rows($result);
echo $count;

then it’s likely that RandomID is an INT field and not a VARCHAR field.

I have a field name ID with int type . The query works fine on that .
But for RandomID, Name, Country fields which are of var char type it is not working
