Php 从不同数组中删除具有相同名称和值的重复键

我有以下8个来自API的关联数组，其中包括一个名为“platform”的键，该键的值为5或21

Array ( [0] => Array ( [category] => 0 [platform] => 5 [date] => 1163894400000 [region] => 2 [human] => 2006-Nov-19 [y] => 2006 [m] => 11 ) [1] => Array ( [category] => 0 [platform] => 5 [date] => 1165017600000 [region] => 5 [human] => 2006-Dec-02 [y] => 2006 [m] => 12 ) [2] => Array ( [category] => 0 [platform] => 5 [date] => 1165449600000 [region] => 3 [human] => 2006-Dec-07 [y] => 2006 [m] => 12 ) [3] => Array ( [category] => 0 [platform] => 5 [date] => 1165536000000 [region] => 1 [human] => 2006-Dec-08 [y] => 2006 [m] => 12 ) [4] => Array ( [category] => 0 [platform] => 21 [date] => 1165017600000 [region] => 5 [human] => 2006-Dec-02 [y] => 2006 [m] => 12 ) [5] => Array ( [category] => 0 [platform] => 21 [date] => 1165795200000 [region] => 2 [human] => 2006-Dec-11 [y] => 2006 [m] => 12 ) [6] => Array ( [category] => 0 [platform] => 21 [date] => 1166140800000 [region] => 1 [human] => 2006-Dec-15 [y] => 2006 [m] => 12 ) [7] => Array ( [category] => 0 [platform] => 21 [date] => 1166486400000 [region] => 3 [human] => 2006-Dec-19 [y] => 2006 [m] => 12 ) )

在我的脚本中，我使用foreach循环在我的网站上显示实际的平台，而不是平台id（在本例中是“Wii”和“GameCube”，而不是5和21）。但是，由于关键“平台”包含8次（4次以“5”为值，4次以“21”为值），因此我在进行回音时有重复项。见下文：

我的代码：

foreach($game_platform_arrays as $key => $innerArray){
    foreach($innerArray as $innerKey => $game_platform){
        if ($innerKey == "platform" and $game_platform == "5"){
            $game_platform = "Wii";
            echo $game_platform;
        }
        if ($innerKey  == "platform" and $game_platform == "21"){
            $game_platform = "Nintendo GameCube";
            echo $game_platform;
        }
    }
}

我的输出：

WiiWiiWiiWiiNintendo GameCubeNintendo GameCubeNintendo GameCubeNintendo GameCube

---

我不知道如何从输出中删除重复项。我的最佳猜测是从数组中删除具有相同名称和值的重复键，但我不确定如何继续。如果有人能给我指出正确的方向，我将不胜感激。

下面是一个例子，说明如何做到这一点：

<?php
$game_platform_arrays = [
0 => [
    'platform' => 5,
    ],
1 => [
    'platform' => 5
],
2 => [
    'platform' => 21
    ],
3 => [
    'platform' => 21
    ]
];
$name = '';
foreach($game_platform_arrays as $key => $innerArray){
   foreach($innerArray as $innerKey => $game_platform){
    if ($innerKey == 'platform' && $game_platform == '5' && $name != 'Wii'){
        echo $name = 'Wii';
    }
    if ($innerKey  == 'platform' && $game_platform == '21' && $name != 'Nintendo GameCube'){
        echo $name = 'Nintendo GameCube';
    }
  }
}
?>

@Adrien，用谷歌搜索一下标题如何question@ThisGuyHasTwoThumbs谢谢我已经看了一眼，但当副本来自不同的数组时，这不起作用。@tereško在发布评论之前，你不要认为我没有做作业，谢谢你的回答！我认为这对我不起作用，因为数组是基于API中的json数据创建的，所以每次我请求时平台都会改变。如果我遗漏了什么，请告诉我。在你的问题中，你说它将是5或21-与你的代码所说的相同。到底是什么问题？请注意，如果游戏平台没有组合在一起，它就不起作用。谢谢你让我知道。我会留意的。你可以通过将name变量添加到数组中，检查它是否存在，如果存在，跳过它来解决这个潜在的问题<代码>如果（在数组（）中）-基本上。
