PHP面向对象——clone关键字

name = &＃39;james&＃39;;
echo &＃39;james`s name is &＃39;.$james->name.&＃39;
&＃39;;
$james2 = clone $james;//克隆
$james2->name = &＃39;james2&＃39;;
echo &＃39;after assign :
&＃39;;
echo &＃39;james`s name is &＃39;.$james->name.&＃39;
&＃39;;
echo &＃39;james2`s name is &＃39;.$james2->name.&＃39;
&＃39;;
$james3 = $james;	   //赋值
$james3->name = &＃39;james3&＃39;;
echo &＃39;after assign:
&＃39;;
echo &＃39;james`s name is &＃39;.$james->name.&＃39;
&＃39;;
echo &＃39;james2`s name is &＃39;.$james3->name.&＃39;
&＃39;;

运行后结果：

james`s name is james
after clone :
james`s name is james
james2`s name is james2
after assign:
james`s name is james3
james2`s name is james3
