This article mainly introduces several methods about PHP multiple inheritance, which has certain reference value. Now I share it with everyone. Friends in need can refer to it
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(); $obj->method3();
interface testA{ function echostr(); } interface testB extends testA{ function dancing($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");
