<?php class MyClass { protected $arr; public function __construct() { $this->arr = array(); } public function getArr() { return $this->arr; } public function append($arr) { $this->$arr[] = $arr; } public function merge($arr) { $this->arr = array_merge($this->arr, $arr); } } $arr = array('a','b'); $obj = new MyClass(); $obj->append($arr);//使用append无法修改类属性 var_dump($obj->getArr()); //output : //array(0){} $obj->merge($arr);//使用merge可以 var_dump($obj->getArr()); //output: //array(2){'a','b'}
