How can the issue of a non-object error when trying to call the num_rows() method be resolved in PHP?

The issue of a non-object error when trying to call the num_rows() method in PHP typically occurs when the result of a query is not properly handled or the query did not return a valid result set. To resolve this issue, you should check if the query executed successfully and if the result set is not empty before calling the num_rows() method. 

// Assuming $result is the variable containing the result set from the query
if ($result && $result->num_rows > 0) {
    // Process the result set
} else {
    // Handle the case when the result set is empty or the query did not execute successfully
}
