PHP5.4新特性之Array dereferencing support

一个盼望已久的特性，终于有了，转之～
 
Array dereferencing是个好东西, 有了Array dereferencing, 以前的这种写法就再也不必要了:
 
    list($name,) = explode(",", "Laruence, male");
?>
取而代之的是:
 
$name = explode(",", "b, x")[0];
另外,  Array derefencing也可以出现再赋值语句的左值中, 也就是理论上你可以这么写:
 
explode(",", "test1, test2")[3] = "phper";
