What potential issue is the user facing with the mysqli_fetch_object() function in the code?

The potential issue the user is facing with the mysqli_fetch_object() function is that it returns an object with property names that correspond to the field names in the result set. If the query does not return any rows, the function will return false, which can cause errors if not handled properly. To solve this issue, it is important to check if the result set is not empty before attempting to fetch objects. 

// Check if there are rows in the result set before fetching objects
if ($result = mysqli_query($connection, $query)) {
    if (mysqli_num_rows($result) > 0) {
        while ($obj = mysqli_fetch_object($result)) {
            // Process the object as needed
        }
    } else {
        echo "No rows found.";
    }
} else {
    echo "Error executing query: " . mysqli_error($connection);
}
