What potential pitfalls are associated with using static methods in PHP, as discussed in the forum thread?

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

class SomeClass {
    private $dependency;

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

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