How can PHP developers optimize performance when calling methods within a class?

To optimize performance when calling methods within a class in PHP, developers can use the "static" keyword to declare methods as static. This allows the methods to be called without instantiating an object of the class, resulting in faster execution. Additionally, developers should avoid using unnecessary global variables and minimize the use of magic methods like __get and __set. 

class MyClass {
    public static function myStaticMethod() {
        // method implementation
    }
}

// Call the static method without instantiating an object
MyClass::myStaticMethod();
