What are the potential pitfalls of using static methods in PHP classes, as seen in the forum thread?

Using static methods in PHP classes can lead to tightly coupled code, making it harder to test and maintain. It can also limit the flexibility of the code and hinder the ability to mock dependencies for testing purposes. To solve this issue, consider using dependency injection to pass dependencies into the class instead of relying on static methods. 

class MyClass {
    private $dependency;

    public function __construct(Dependency $dependency) {
        $this->dependency = $dependency;
    }

    public function myMethod() {
        $this->dependency->doSomething();
    }
}
