本文实例讲述了PHP基于SPL实现的迭代器模式。分享给大家供大家参考，具体如下：
现在有这么两个类，Department部门类、Employee员工类：
//部门类
class Department{
private $_name;
private $_employees;
function __construct($name){
$this->_name = $name;
$this->employees = array();
}
function addEmployee(Employee $e){
$this->_employees[] = $e;
echo "员工{$e->getName()}被分配到{$this->_name}中去";
}
}
//员工类
class Employee{
private $_name;
function __construct($name){
$this->_name = $name;
}
function getName(){
return $this->_name;
}
}
//应用：
$lsgo = new Department('LSGO实验室');
$e1 = new Employee("小锦");
$e2 = new Employee("小猪");
$lsgo->addEmployee($e1);
$lsgo->addEmployee($e2);
