Class

Basic class definitions begin with the keyword class, followed by a class name, followed by a pair of curly braces which enclose the definitions of the properties and methods belonging to the class.

A class name may be validated with the following regex: ^[a-zA-Z_\x80-\xff][a-zA-Z0-9_\x80-\xff]*$; and by avoiding a list of PHP keywords, such as namespace, class, interface, etc.

<?php

class X {
    const CONSTANT = 1;

    private $property = 2;

    function method() {
        /// and more
    }

}

?>
