Question

当前正在使用C进行项目开发，但是我必须生成一个大型结构，由于我对PHP更加熟悉，因此我认为这将在PHP中生成。

我有2个数组。第一个很简单（比这大得多，但我认为这足以复制问题）：

$vehicles = [
    'vehicleSuper' => [ "adder", "autarch", "banshee2", "bullet"  ],
    'vehicleSport' => [ "alpha", "banshee", "bestiagts", "blista2" ],
    //...
];

第二个数组如下：

$textures = [
    'candc_apartments' => [
        "limo2_b", "limo2",
    ],
    'candc_default' => [
        "marshall_flag18_b", "mesa_b", "rentbus", "marshall_flag21_b", "crusader", "boxville4", "buzzard_b", "dukes2_b", "dukes",
    ],
    'lgm_default' => [
        "hotknife", "coquette", "voltic_tless", "vacca", "infernus", "cogcabri_b", "stinger_b", "banshee_b", "ztype", "ninef", "jb700", "superd", "monroe_b", "rapidgt2_b", "khamel", "comet2_b", "cheetah_b", "rapidgt_b", "stinger", "carbon_b", "surano_convertable_b", "rapidgt2", "infernus_b", "jb700_b", "ninef_b", "stingerg", "superd_b", "bullet_b", "ztype_b", "hotknife_b", "cogcabri", "surano_convertable", "rapidgt", "stingerg_b", "coquette_b", "bullet", "carbon", "ninef2", "carboniz", "cheetah", "adder_b", "entityxf", "adder", "feltzer",
    ],
];

现在我使用上面的2个数组生成这样的列表：

echo '<pre>';

foreach($vehicles as $category => $val) {
    echo "vehicleSpawner " . $category . "[] = {\n";
    foreach($val as $item) {
        echo "  { \"" . $item . "\", \"" . array_search($item, array_column($textures, $item)) . "\", \"\" },\n";
    }
    echo '}';
echo '<hr>';
}

这将输出类似于：

{ "adder", "", "" },

最后2个值为空。 我要实现的目标：用$textures数组中的值填充这些值。在这种情况下，我试图像这样填充它：

// arg 1: name from $vehicles
// arg 2: key from $textures
// arg 3: val from $textures
{ "adder", "lgm_default", "adder" },

当前，我的array_search($item, array_column($textures, $item))方法似乎不起作用。我将如何去工作呢？感谢您的帮助，谢谢大家！

Answer 1

array_column($textures, $item)将在名为$textures的数组$item键中搜索，但是没有该名称的键，因此返回false，您需要在{{1}上循环}数组并搜索值$textures是否存在：

$item

Answer 2

如果要在给定的一对子阵列中查看多个匹配项，array_intersect()将比较两个子阵列一次并迭代结果。这比对子数组之一的每个元素运行全新的array_search()调用更为有效。

代码：（Demo）

foreach($vehicles as $category => $v_vals) {
    echo "vehicleSpawner " . $category . "[] = {\n";
    foreach($textures as $k => $t_vals) {
        foreach (array_intersect($v_vals, $t_vals) as $match) {
            echo "  { \"$match\", \"$k\", \"$match\" },\n";
        }
    }
    echo "}\n";
}

输出：

vehicleSpawner vehicleSuper[] = {
  { "adder", "lgm_default", "adder" },
  { "bullet", "lgm_default", "bullet" },
}
vehicleSpawner vehicleSport[] = {
}

如果这不是您想要的确切输出格式/结构，可以对其进行调整以适应。

PHP-数组搜索不返回任何内容
