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.

完整的错误信息是什么？ var_dump($this->session->userdata('userinfo')); //贴出结果

谢谢楼上的高手相助,打印出那个变量的值是这样子的,但是在一个方法后面直接跟[]取值是正确的PHP语法么?

$u1_nick = $this->session->userdata('userinfo')['screen_name'];
这种用法只在 php5.4 中是合法的

恩,非常感谢楼上的,我们是一个异地合作团队,估计是我们的PHP版本不一致,我这边确实是PHP 5.3.应该是这个问题.谢谢
