What are common pitfalls in PHP class design when methods are dependent on each other for proper execution?

Common pitfalls in PHP class design when methods are dependent on each other for proper execution include tightly coupling methods, making the class harder to maintain and test, and potentially leading to unexpected behavior. To solve this issue, it is recommended to refactor the code to reduce dependencies between methods and promote a more modular and flexible design. 

class MyClass {
    private $data;

    public function setData($data) {
        $this->data = $data;
    }

    public function processData() {
        // Process data
    }

    public function displayData() {
        if ($this->data === null) {
            throw new Exception("Data not set");
        }

        // Display data
    }
}
