In PHP, what are some strategies for ensuring method calls are made in the correct order within a class to maintain functionality and prevent errors?

To ensure method calls are made in the correct order within a class in PHP, you can use access modifiers like private or protected to restrict access to certain methods. Additionally, you can use dependency injection to pass necessary dependencies to methods, ensuring they are called in the correct order. Lastly, you can implement a design pattern like the Template Method pattern to define the skeleton of an algorithm in the base class and allow subclasses to override specific steps. 

class MyClass {
    private function step1() {
        // implementation
    }
    
    private function step2() {
        // implementation
    }
    
    public function executeSteps() {
        $this->step1();
        $this->step2();
    }
}

$myObject = new MyClass();
$myObject->executeSteps();
