【问题描述】：

我有一个用于显示调查的二维数组。该数组包含 63 行（问题）。每行包含一个 GpDesc（分组，即领导特质）和一个 QueDesc（问题）。有 9 种不同的 GpDesc。我想在第一次出现时回显 GpDesc，然后回显该组中的问题和单选按钮，直到下一个 GpDesc。我知道我需要一个用于 GpDesc 数量的外部循环和一个用于该组内问题的内部循环，但我不知道该怎么做。这是 $varArray 的一部分：

Array ( 
    [0] => Array ( 
        [GpID] => 1168 
        [GpDesc] => LEADERSHIP TRAITS 
        [QueID] => 10266 
        [QueDesc] => Is visionary 
        [GpQue] => 0 
    ) 
    [1] => Array ( 
        [GpID] => 1168 
        [GpDesc] => LEADERSHIP TRAITS 
        [QueID] => 10267

        [QueDesc] => Involves faculty in strategic planning 
        [GpQue] => 0 
    ) 
    [12] => Array (

        [GpDesc] => 

有人可以帮忙吗？

【问题讨论】：

你能用print_r($array); 的结果或至少出现几次的结果替换那个转储

抱歉弄得一团糟，但这里是其中的一部分。

Cannot output multi-dimensional array的可能重复
