/*

Generics in PHP are a way to define classes, interfaces, and methods 

that can work with different types of data, without the need to create 

multiple copies of the same code for each type.

​

PHP does not have built-in support for generics like other languages 

such as C# and Java. However, you can use type hints and type casting to 

achieve similar functionality.

class MyClass {

    public function genericMethod(array $items) {

        // Do something with the $items array

    }

}

//In this example, the genericMethod() can accept any type of array.

​

​

//You can also use type casting to achieve similar functionality

function genericMethod($items) {

    $items = (array) $items;

    // Do something with the $items array

}

//In this example, the genericMethod() can accept any type of data and cast it to an array.

​

/*

It's important to note that in PHP, you can't specify types for variables 

or return types for methods, so you cannot have type-safe generics like in

C# or Java. However, by using type hints and type casting, you can make your 

code more robust and ensure that it works correctly with different types of data.
