我有一个数组。我想以系统的方式创建一个 Excel 以用于其他目的。

下面是我的数组：

$data = [
0 => array:3 [
  "sku" => "CR3297RC-S"
  "url" => "htt://www.abc/dev/shop/CR3297RC_1.jpeg"
  "label" => "shopify"
]
1 => array:3 [
  "sku" => "CR3297RC-S"
  "url" => "htt://www.abc/dev/shop/CR3297RC_2.jpeg"
  "label" => "shopify"
]
2 => array:3 [
"sku" => "CR3297RC-S"

上面是我的数组。现在，如果看到键 4 和 9，它们就有带字符串的图像。 我想为每个即将到来的 SKU 做一个记录，但在最后。 现在我想要一个 SKU Ex.CR3297RC-S 使该 SKU 的 SWATCH 图像只在最后一次出现。 就像删除键 4 并且每个即将到来的 SKU 只有键 9。

喜欢下面：

 $data = [
 0 => array:3 [
  "sku" => "CR3297RC-S"
  "url" => "htt://www.abc/dev/shop/CR3297RC_1.jpeg"
  "label" => "shopify"
]
1 => array:3 [
  "sku" => "CR3297RC-S"
  "url" => "htt://www.abc/dev/shop/CR3297RC_2.jpeg"
  "label" => "shopify"
]
2 => array:3 [
  "sku" => "CR3297RC-S"
  "url" => "htt://www.abc/dev/shop/CR3297RC_3.jpeg"
  "label" => "shopify"
]
3 => array:3 [
 "sku" => "CR3297RC-S"
 "url" => "htt://www.abc/dev/shop/CR3297RC_4.jpg"
 "label" => "shopify"
]
4 => array:3 [
 "sku" => "CR3297RC-S"
 "url" => "htt://www.abc/dev/wal/CR3297RC_1.jpeg"
 "label" => "amazon"
]
5 => array:3 [
 "sku" => "CR3297RC-S"
 "url" => "htt://www.abc/dev/wal/CR3297RC_2.jpeg"
 "label" => "amazon"
]
6 => array:3 [
 "sku" => "CR3297RC-S"
 "url" => "htt://www.abc/dev/wal/CR3297RC_3.jpeg"
 "label" => "amazon"
]
7 => array:3 [
 "sku" => "CR3297RC-S"
 "url" => "htt://www.abc/dev/wal/CR3297RC_4.jpg"
 "label" => "amazon"
]
8 => array:3 [
 "sku" => "CR3297RC-S"

 "label" => ""
]

要在 PHP 中检测数组变量中的重复项，可以使用 array_count_values 函数。此函数计算数组中值的出现次数并返回一个关联数组，其中键是原始数组中的值，值是计数。

举个例子：

$array = array(1, 2, 3, 4, 4, 5, 5, 5);
$counted = array_count_values($array);
$duplicates = array();

foreach ($counted as $key => $value) {
    if ($value > 1) {
        $denter code hereuplicates[] = $key;
    }
}

if (count($duplicates) > 0) {
    echo "Duplicates found: " . implode(', ', $duplicates);
} else {
    echo "No duplicates found.";
}

在这个例子中，我们有一个包含一些重复值的数组 $array。我们使用 array_count_values 来计算数组中每个值的出现次数，并将结果存储在 $counted 中。然后我们遍历 $counted 并检查是否有任何值大于 1（表示重复）。如果是这样，我们将相应的键（原始值）添加到 $duplicates 数组中。最后，我们检查 $duplicates 是否非空，如果是，则输出重复项。
