Question

Array
(
    [0] => Array
        (
            [Handle] => example-t-shirt
            [Title] => Example T-Shirt            
            [Vendor] => Acme
            [Type] => Shirts
        )

    [1] => Array
        (
            [Handle] => example-t-shirt
            [Title] => 1
            [Vendor] => 2
            [Type] => 3
        )

    [2] => Array
        (
            [Handle] => example-t-shirt
            [Title] => 4
            [Vendor] => 5
            [Type] => 6
        )

)

我有这个数组，我想转换它像

Array
(
    [Handle] => example-t-shirt,example-t-shirt,example-t-shirt
    [Title] => Example T-Shirt,1,4
    [Vendor] => Acme,2,5
    [Type] => Shirts,3,6
)

像句柄或标题这样的数组的更多关键也没有修复，这些也是动态的。提前谢谢

Answer 1

首先需要将其生成为数组：

<?php
    $mainArray = array(
        array(
            "Handle" => "example-t-shirt",
            "Title" => "Example T-Shirt",
            "Vendor" => "Acme",
            "Type" => "Shirts"
        ),
        array(
            "Handle" => "example-t-pant",
            "Title" => "Example T-Pant",
            "Vendor" => "Meca",
            "Type" => "Pants"
        )
    );
    $finalArray = array(
        "Handle" => array(),
        "Title" => array(),
        "Vendor" => array(),
        "Type" => array()
    );
    foreach ($mainArray as $current)
        foreach ($current as $key => $value)
            $finalArray[$key][] = $value;
?>

之后，$finalArray中的每一个都应加入。

foreach ($finalArray as $key => $value)
    $finalArray[$key] = implode(", ", $value);

所以你的最终代码将是：

<?php
    $mainArray = array(
        array(
            "Handle" => "example-t-shirt",
            "Title" => "Example T-Shirt",
            "Vendor" => "Acme",
            "Type" => "Shirts"
        ),
        array(
            "Handle" => "example-t-pant",
            "Title" => "Example T-Pant",
            "Vendor" => "Meca",
            "Type" => "Pants"
        )
    );
    $finalArray = array(
        "Handle" => array(),
        "Title" => array(),
        "Vendor" => array(),
        "Type" => array()
    );
    foreach ($mainArray as $current)
        foreach ($current as $key => $value)
            $finalArray[$key][] = $value;
    foreach ($finalArray as $key => $value)
        $finalArray[$key] = implode(", ", $value);
?>

<强>输出

Array
(
    [Handle] => example-t-shirt, example-t-pant
    [Title] => Example T-Shirt, Example T-Pant
    [Vendor] => Acme, Meca
    [Type] => Shirts, Pants
)

Answer 2

这是一个使用array_walk_recursive

的工作示例

$mainArray = array(
        array(
            "Handle" => "example-t-shirt",
            "Title" => "Example T-Shirt",
            "Vendor" => "Acme",
            "Type" => "Shirts"
        ),
        array(
            "Handle" => "example-t-pant",
            "Title" => "Example T-Pant",
            "Vendor" => "Meca",
            "Type" => "Pants"
        )
    );

$final = array();

array_walk_recursive($mainArray, function($item, $key) use (&$final){
  $final[$key] = isset($final[$key]) ?  $item .', '. $final[$key] : $item;
});

var_dump($final);

Answer 3

试试这个：

<?php
$temp = array(
    array(
            "Handle" => "example-t-shirt",
            "Title" => "Example T-Shirt",          
            "Vendor" => "Acme",
            "Type" => "Shirts"
          ),

    array(
            "Handle" => "example-t-shirt",
            "Title" => 1,
            "Vendor" => 2,
            "Type" => 3
        ),

    array(
            "Handle" => "example-t-shirt",
            "Title" => 4,
            "Vendor" => 5,
            "Type" => 6
    )
);

$result = array();

foreach($temp as $t){
  if (is_array($t)){
    foreach ($t as $k=>$r){
        if(array_key_exists($k,$result)){
            $result[$k] .= ','.$r;
        } else {
            $result[$k] = $r;
        }
    }
  }
}
 echo '<pre>';
 print_r($result);
?>
