Description:
------------
I want to execute a query that has no parameters. To be consistent, I would like to prepare this query as I do all other queries.

In the Test script below, $stmt = ... executes ok.

When the mysqli_stmt_bind_param(...) is executed the interpreter complains:
Fatal error: Uncaught ValueError: mysqli_stmt_bind_param(): Argument #2 ($types) cannot be empty...

The manual page for mysqli_prepare states that 0 or more place holder ? can appear in the SQL, at the top level (no quotes), only in places where values are expected, etc... My SELECT statement complies with all that.

So I tried deleting the mysqli_stmt_bind_param(...) line, because there are no parameters to bind. In this case, the interpreter complains when the mysqli_stmt_execute($stmt); is executed that no parameters have been bound! But there are no parameters in this SELECT query.

No changes were made tp php.ini

It looks like a core issue to me.

My version of php is reported as PHP version: 8.0.5, so I chose the closest match 8.08 ?

Test script:
---------------
$stmt = mysqli_prepare($con, "SELECT _id, _user_id, _email FROM $members WHERE _user_id IS NULL");
mysqli_stmt_bind_param($stmt, "");
mysqli_stmt_execute($stmt);


Expected result:
----------------
Please provide a workaround or technique I can use now to prepare a query with 0 parameters.


Actual result:
--------------
Stack trace: #0 C:\xampp\htdocs\sample.php(nnn): mysqli_stmt_bind_param(Object(mysqli_stmt), '') #1 {main} thrown in C:\xampp\htdocs\sample.php on line nnn
