基础问题,菜鸟求救,非常感谢.
$u1_nick = $this->session->userdata('userinfo')['screen_name'];

如上的代码,在NetBeans里面报错,报错是:
"语法错误:
预期: instanceof, as, ->, =>, }, ',', OR, XOR, AND, =, +=, -=, *=, /=, .=, %=, &=, |+, ^=, >=, ?, ';', ||, &&, |, ^, &, ==, !=, ===, !==, =+, , >, +, -, *, /, %, '.', ++, --, ], ), ':'
"
本人纯粹PHP新手,请大家指导一下,为什么在别人那儿是没问题的,是不是我有些PHP的特性没打开?非常感谢.

------解决方案--------------------
完整的错误信息是什么? var_dump($this->session->userdata('userinfo')); //贴出结果
------解决方案--------------------
$u1_nick = $this->session->userdata('userinfo')['screen_name'];
这种用法只在 php5.4 中是合法的
