How do frameworks like Symfony and Laravel adhere to or deviate from the Liskov Substitution Principle recommendations regarding Exception handling?

The Liskov Substitution Principle states that objects of a superclass should be replaceable with objects of its subclasses without affecting the program's correctness. When it comes to exception handling, this means that subclasses should not throw exceptions that are not declared in the superclass. Frameworks like Symfony and Laravel typically adhere to this principle by ensuring that exceptions thrown by subclasses are compatible with the exceptions declared in the superclass.

// Example of adhering to Liskov Substitution Principle in exception handling

class SuperClass {
    public function doSomething() {
        // code that may throw an exception
    }
}

class SubClass extends SuperClass {
    public function doSomething() {
        try {
            // code that may throw a specific exception
        } catch (SpecificException $e) {
            // handle the specific exception
        }
    }
}
