How to use chained methods to make your PHP code beautiful

Chaining methods is a programming technique that allows you to call multiple methods on an object in a single line of code. This can make your code easier to read, maintain, and express.

To use chained methods in PHP, you simply return the current object from each method to be chained. For example, the following code shows a simple example of a chain method:

class User
{
    public function setName($name)
    {
        $this->name = $name;
        return $this;
    }
    public function setEmail($email)
    {
        $this->email = $email;
        return $this;
    }
    public function save()
    {
        // Save the user to the database
    }
}
$user = new User();
$user->setName('John Doe')->setEmail('john.doe@example.com')->save();

In the above code, we use the chain method to set the user's name and email address and then save the user to the database. We are able to do this because every method returns the current object.

Chained methods can be used for a variety of tasks, such as:

* Validating user input
