Web Reference: Check the callable manual to see all the different ways to pass a function as a callback. I copied that manual here and added some examples of each approach based on your scenario. A PHP function is passed by its name as a string. Static class methods can be used without instantiating an object of that class by either, creating an array with the class name at index 0 and the method name at index 1, or by using the special syntax with the scope resolution operator ::, as in 'ClassName::methodName'. A class is defined with the class keyword, followed by the name of the class and a pair of curly braces ( {}). All its properties and methods go inside the braces.
