本文实例讲述了php 多继承的几种常见实现方法。分享给大家供大家参考,具体如下:
class Parent1 {
function method1() {}
function method2() {}
}
class Parent2 {
function method3() {}
function method4() {}
}
class Child {
protected $_parents = array();
public function Child(array $parents=array()) {
$this->_parents = $parents;
}
public function __call($method, $args) {
// 从“父类"中查找方法
foreach ($this->_parents as $p) {
if (is_callable(array($p, $method))) {
return call_user_func_array(array($p, $method), $args);
}
}
// 恢复默认的行为,会引发一个方法不存在的致命错误
return call_user_func_array(array($this, $method), $args);
}
}
$obj = new Child(array(new Parent1(), new Parent2()));
print_r( array($obj) );die;
$obj->method1();
$obj->method3();
运行结果:
Array ( [0] => Child Object ( [_parents:protected] => Array ( [0] => Parent1 Object ( )
[1] => Parent2 Object ( )
)
)
)
interface testA{
function echostr();
}
interface testB extends testA{
function dancing($name);
}
class testC implements testB{
function echostr(){
echo "接口继承,要实现所有相关抽象方法!";
echo "<br>";
}
function dancing($name){
echo $name."正在跳舞!";
}
}
$demo=new testC();
$demo->echostr();
$demo->dancing("模特");
运行结果:
php 多继承接口继承,要实现所有相关抽象方法! 模特正在跳舞!
