Question

初始数组：

Array 
( 
    [0] => Array ( 
        [0] => "Kate" 
        [1] => Array ( [0] => 1 [1] => 30 [2] => 11 ) 
        [2] => "Seattle" 
    ) 
    [1] => Array ( 
        [0] => "Kate" 
        [1] => Array ( [0] => 100 [1] => 7 [2] => 55 ) 
        [2] => "Seattle" 
    ) 
    [2] => Array ( 
        [0] => "Mike" 
        [1] => Array ( [0] => 1 [1] => 2 [2] => 13 ) 
        [2] => "New York" 
    ) 
    [3] => Array ( 
        [0] => "Paul" 
        [1] => Array ( [0] => 5 [1] => 34 [2] => 9 ) 
        [2] => "Chicago" 
    ) 
    [4] => Array ( 
        [0] => "Mike" 
        [1] => Array ( [0] => 1 [1] => 30 [2] => 13 ) 
        [2] => "New York" 
    ) 
)

期望输出：

Array 
( 
    [0] => Array ( 
        [0] => "Kate" 
        [1] => Array ( [0] => 1 [1] => 30 [2] => 11 [3] => 100 [4] => 7 [5] => 55 ) 
        [2] => "Seattle" 
    ) 
    [1] => Array ( 
        [0] => "Mike" 
        [1] => Array ( [0] => 1 [1] => 2 [2] => 13 [3] => 30 ) 
        [2] => "New York" 
    ) 
    [2] => Array ( 
        [0] => "Paul" 
        [1] => Array ( [0] => 5 [1] => 34 [2] => 9 ) 
        [2] => "Chicago" 
    ) 
)

我想基于[0]中的字符串值来简化数组，如“Kate”，“Mike”或“Paul”。在这样做时，我想合并[1]中的数组，并使其成为唯一的，作为“Mike”在期望输出中的数组。

我不知道该做什么或从哪里开始。请帮忙！

好的，您正在处理数组，因此您可能需要使用functions that modify arrays。您很可能还需要一个foreach循环来迭代数组。辅助变量也可能有用。

它类似于儿童玩具，它们将物体插入各种形状。只需将值相互匹配即可。如果它们合适则合并它们。只要你不在乎学习它就很难。
