Are there any potential pitfalls to be aware of when deleting functions in inherited classes in PHP?

When deleting functions in inherited classes in PHP, one potential pitfall to be aware of is that it can break the code if the parent class relies on that function being present in the child class. To solve this issue, you can either override the function in the child class with an empty implementation or throw an exception to indicate that the function should not be called. 

class ParentClass {
    public function someFunction() {
        // Do something
    }
}

class ChildClass extends ParentClass {
    // Deleting the function from the child class
    // public function someFunction() {
    //     // Do something else
    // }
    
    // Override with an empty implementation
    public function someFunction() {
        // Do nothing
    }
    
    // Throw an exception
    // public function someFunction() {
    //     throw new Exception("This function should not be called in the child class.");
    // }
}
