在java开发中广泛的使用了IOC的思想,在PHP中同样也在广泛使用。
interface Coder
{
public function coding();
}
实现类Javaer
class Javaer implements Coder
{
var $name; public function __construct($name)
{
$this->name = $name;
}
public function coding()
{
echo "$this->name.is coding java code.<br>";
}
}
实现类Phper
class Phper implements Coder
{
var $name; public function __construct($name)
{
$this->name = $name;
}
public function coding()
{
echo "$this->name.is coding php code.<br>";
}
}
业务逻辑类Task
class Task
{
var $name;
var $owner; public function __construct($name)
{
$this->name = $name;
} public function setOwner($owner){
$this->owner = $owner;
} public function start()
{
echo "$this->name.started!<br>";
$this->owner->coding();
}
}
测试
$task = new Task("Task #1");
// $owner = new Phper("xiaohb");
$owner = new Javaer("xiaoxiao");
$task->setOwner($owner);
$task->start();
代码的可维护和拓展性显而易见了
