<?php
namespace abc;
class test1 {
public $a = ' aaa';
public function hello(){
echo 'hello' . $this->a . PHP_EOL;
}
}
class test2 {
public function hello(){
$obj = new test1;
//var_dump(get_class($obj)); //always abc\test1
$obj->hello();
}
}
namespace def;
class test1 extends \abc\test1 {
public $a = ' bbb';
}
class test2 extends \abc\test2 {
}
(new test2)->hello();

下面这段这么修改:
