Here is a cleaner looking copy of your code.

if($_SERVER['REQUAST_METHOD']=='POST')
{
	include 'connect.php'; 
	$sql = "SELECT * FROM users where email='$email' and password='$password'";
	$result = mysqli_query($sql);
	if($result)
	{
		$num = mysqli_num_rows($con,$result);
		if($num > 0)
			echo "login successful";
		else
			echo "invaild";
	}

Now if you just clean up your spelling it just may work.

While you are fixing the spelling, there are one or two other things you might want to consider.

  • Don't use SELECT *. The more data you fetch from the server, the slower the query and you don't need every column. In this case you would want the user's id to store in your session variables as evidence of logging in.
  • Don't put user-provided variable directly ito your query. It makes it vulnerable to an SQL injection attack. Use prepared statements instead.
  • Don't store passwords as plain text, it's insecure. Use password_hash() when storing and password_verify() when checking.
  • Check the manual for the correct parameters to us with mysql_query().

If you follow the above you should end up with somethng like

    $res = $con->prepare("SELECT user_id
                               , password 
                          FROM users
                          WHERE email = ?     
                         ");
    $res->bind_param('s', $email);
    $res->execute();
    $res->bind_result($user_id, $hash);
    if ($row = $res->fetch()) {
      if (password_verify($password, $hash))  {
        $_SESSION['user_id'] = $user_id;
        echo "login successful";
      }
      else {
        echo "invaild";
      }
    }
    else echo "invalid";

A final piece of advice. As you haven't invvested a great deal of time into learning mysqli, now is a good time tme to switch to the better PDO interface. In which case the code becomes

    $res = $con->prepare("SELECT user_id
                               , password 
                          FROM users
                          WHERE email = ?     
                         ");
    $res->execute([ $email ]);
    if ($row = $res->fetch()) {
      if (password_verify($password, $row['password']))  {
        $_SESSION['user_id'] = $row['user_id'];
        echo "login successful";
      }
      else {
          echo "invaild";
      }
    }
    else echo "invalid";
