当在对象后面添加()时候调用 __invoke
<?php class Person { private $name; private $age; public function __construct($name,$age) { $this->name = $name; $this->age = $age; } function __invoke($a,$b) { echo "{$a}{$b}"; } } $a = new Person("zs",10); $a("ss",1); //输出ss1
autoload 自动加载类文件,参数是类名
function __autoload($classname) { include "{$classname}".".php"; }
