简单问题，但是估计能答上的不多
情况A

<br />
return array_flip($result)[$parm];<br />
Copy after login


情况B
<br />
$result =  array_flip($result);<br />
return $result[$parm];<br />
Copy after login




编辑器都是 zend stuido 9 谁能解释下为什么有的编辑器不提示这个错误，有的编辑器提示这个错误
------解决方案--------------------
$result =  array_flip($result);
return $result[$parm];
这是传统的写法

return array_flip($result)[$parm];
这是php5.4新增的写法

不是编辑器是否报错，而是php是否报错！
