Why does mysqli_query() require a MySQLi object as its first parameter?

Error: mysqli_query() Expects First Parameter to Be MySQLi

Problem:

When using a class to connect to a MySQL database, an error is encountered:

Warning: mysqli_query() expects parameter 1 to be mysqli, object given

Underlying Issue:

The issue arises when attempting to execute a query using mysqli_query(). The function expects the first parameter to be a MySQLi object, but the code is currently passing an instance of the class instead.

Solution:

To resolve the error, pass $connection->myconn instead of $connection as the first parameter to mysqli_query().

Here is the corrected code:

$result = mysqli_query($connection->myconn, $query);

Explanation:

The class property $myconn holds the MySQLi connection object. By passing $connection->myconn, we are correctly passing the required MySQLi object to mysqli_query().
