In the provided PHP code, what are the best practices for handling object instantiation and method calls to avoid errors?

When handling object instantiation and method calls in PHP, it is important to check if the object exists before calling its methods to avoid errors. One way to do this is by using conditional statements to ensure that the object is instantiated before calling its methods. This helps prevent "Call to a member function on null" errors that may occur when trying to access methods of a non-existent object. 

// Check if the object is instantiated before calling its methods
if ($object instanceof ClassName) {
    $object->methodName();
}
