class UniqueID { public static function generate() { return uniqid(); } } echo UniqueID::generate(); // Output: 60bf12a8785e6
class Math { public static function factorial($num) { if ($num <= 1) { return 1; } return $num * self::factorial($num - 1); } } echo Math::factorial(5); // Output: 120This code creates a class called `Math` with a static method `factorial` that calculates the factorial of a number recursively. The code then calls the `factorial` method using the class name and the `::` operator. This example could be part of a package library that provides various mathematical functions and methods. In summary, PHP static method is a useful feature for creating functions that belong to a class rather than an instance of the class. It can be used for various purposes and can be part of a package library that provides utility functions or mathematical functions, among other things.
