What does the error message "Fatal error: Call to a member function alterDatabase() on a non-object" indicate in PHP?

The error message "Fatal error: Call to a member function alterDatabase() on a non-object" indicates that the function alterDatabase() is being called on a variable that is not an object. This could happen if the variable is not initialized properly or if the object was not created successfully.

// Initialize the database object

if ($database instanceof Database) {
    $database->alterDatabase();
} else {
    echo "Database object not created successfully.";
}
