<?php
class MyClass
{
    const MY_CONST      = 'value'; // 常量

    static $staticVar   = 'static';

    // 属性必须声明其作用域
    public $property    = 'public';
    public $instanceProp;
    protected $prot = 'protected'; // 当前类和子类可访问
    private $priv   = 'private';   // 仅当前类可访问

    // 通过 __construct 来定义构造函数
    public function __construct($instanceProp) {
        // 通过 $this 访问当前对象
        $this->instanceProp = $instanceProp;
    }

    // 方法就是类中定义的函数
    public function myMethod()
    {
        print 'MyClass';
    }

    final function youCannotOverrideMe()
    {
    }

    public static function myStaticMethod()
    {

    }
}

echo MyClass::MY_CONST;    // 输出 'value';
echo MyClass::$staticVar;  // 输出 'static';
MyClass::myStaticMethod(); // 输出 'I am static';
