PHP 类

这是一个类示例。

class Personal [extends Parents]
{
    var $name;
    var $age;
    var $sex;
    function Personal()
    {
        $this->name = "";
        $this->age = 0;
        $this->sex = "";
    }
    function Set($n, $a, $s)
    {
        $this->name = $n;
        $this->age = $a;
        $this->sex = $s;
    }
    function Printit()
    {
        echo($this->name.$this->age.$this->sex);
    }
}

$p = new Personal();
$p->Set('John',20,'man');
$p->Printit();

说明	意义
Personal	类名及构造函数名
extends Parents	从父类继承，可选
$this	引用类实例的指针
function	定义函数及过程
new	生成实例
