Question

我有一个数组，我似乎无法弄清楚如何查看每个数组项并检查[Product Name]是否与另一个数组项[Product Name]匹配？

以下是示例数据。 例如，array[0]和array[1]两者都具有相同的[Product Name] test但[Variant Name]或[Variant Full Stock]之类的值不同。我希望能够找到这样的匹配并将它们以某种方式组合到一个数组中，但不覆盖任何内容。

Array (
    [0] => Array (
            [Product Name] => test
            [Variant Name] => Default
            [Variant SKU] => 
            [Variant In Stock] => 1
            [Variant Full Stock] => 1
            [id] => 0
        )
    [1] => Array (
            [Product Name] => test
            [Variant Name] => testingVar
            [Variant SKU] => 
            [Variant In Stock] => 1
            [Variant Full Stock] => 2
            [id] => 1
        )
    [2] => Array (
            [Product Name] => another test
            [Variant Name] => Default
            [Variant SKU] => 
            [Variant In Stock] => 1
            [Variant Full Stock] => 1
            [id] => 2
        )
)

理想情况下，我想将上面的数组转换为一个输出如下内容的新数组：

Array (
    [0] => Array (
        [0] => Array (
            [Product Name] => test
            [Variant Name] => Default
            [Variant SKU] => 
            [Variant In Stock] => 1
            [Variant Full Stock] => 1
            [id] => 0
        )
        [1] => Array (
            [Product Name] => test
            [Variant Name] => testingVar
            [Variant SKU] => 
            [Variant In Stock] => 1
            [Variant Full Stock] => 2
            [id] => 1
        )
    )
    [1] => Array (
        [Product Name] => another test
        [Variant Name] => Default
        [Variant SKU] => 
        [Variant In Stock] => 1
        [Variant Full Stock] => 1
        [id] => 2
    )
)

任何解决方案？

您需要做的就是迭代数组并按Product Name

分组

$data =
    array(
        array(
            "Product Name" => "test",
            "Variant Name" => "Default",
            "Variant SKU" => "",
            "Variant In Stock" => 1,
            "Variant Full Stock" => 1,
            "id" => 0
        ),
        array(
            "Product Name" => "test",
            "Variant Name" => "testingVar",
            "Variant SKU" => "",
            "Variant In Stock" => 1,
            "Variant Full Stock" => 2,
            "id" => 1
        ),
        array(
            "Product Name" => "another test",
            "Variant Name" => "testingVar",
            "Variant SKU" => "",
            "Variant In Stock" => 1,
            "Variant Full Stock" => 2,
            "id" => 2
        ),
    );

$result = array();

foreach($data as $item) {
    $key = $item["Product Name"];
    $result[$key][] = $item;
}

$result看起来像这样：

array(2) {
  ["test"]=>
  array(2) {
    [0]=>
    array(6) {
      ["Product Name"]=>
      string(4) "test"
      ["Variant Name"]=>
      string(7) "Default"
      ["Variant SKU"]=>
      string(0) ""
      ["Variant In Stock"]=>
      int(1)
      ["Variant Full Stock"]=>
      int(1)
      ["id"]=>
      int(0)
    }
    [1]=>
    array(6) {
      ["Product Name"]=>
      string(4) "test"
      ["Variant Name"]=>
      string(10) "testingVar"
      ["Variant SKU"]=>
      string(0) ""
      ["Variant In Stock"]=>
      int(1)
      ["Variant Full Stock"]=>
      int(2)
      ["id"]=>
      int(1)
    }
  }
  ["another test"]=>
  array(1) {
    [0]=>
    array(6) {
      ["Product Name"]=>
      string(12) "another test"
      ["Variant Name"]=>
      string(10) "testingVar"
      ["Variant SKU"]=>
      string(0) ""
      ["Variant In Stock"]=>
      int(1)
      ["Variant Full Stock"]=>
      int(2)
      ["id"]=>
      int(2)
    }
  }
}

不完全是你的想法，但也许更有用？

虽然你已经有了答案，但我开始编写代码，所以我想完成它。

$newar=array();
$k=0;
while($ar[0])
{
    $keys=array();
    foreach($ar as $k2=>$v2)if($ar[0]['Product Name']==$ar[$k2]['Product Name']&&$k2!=0)$keys[]=$k2;
    $newar[$k]=array($ar[0]);
    unset($ar[0]);
    foreach($keys as $x)
    {
        $newar[$k][]=$ar[$x];
        unset($ar[$x]);
    }
    ++$k;
    $ar=array_values($ar);
}
$ar=$newar;

例如，这个：

Array
(
    [0] => Array
        (
            [Product Name] => test
        )

    [1] => Array
        (
            [Product Name] => test
        )

    [2] => Array
        (
            [Product Name] => another test
        )

)

将成为：

Array
(
    [0] => Array
        (
            [0] => Array
                (
                    [Product Name] => test
                )

            [1] => Array
                (
                    [Product Name] => test
                )

        )

    [1] => Array
        (
            [0] => Array
                (
                    [Product Name] => another test
                )

        )

)

在PHP数组中查找匹配，然后组合数组而不进行任何覆盖
