Question

我有像下面这样的json数组：

Array
(
    [total] => 1
    [rows] => Array
    (
        [0] => Array
            (
                [date] => 2014-11-12
                [A] => 1
                [B] => 2
                [C] => 2
                [D] => No
                [E] => New
                [F] => New
                [G] => 1
                [H] => 1
                [I] => 1
                [A] => 1
                [J] => 1
                [B] => 1
            )
        [1] => Array
            (
                [date] => 2014-12-12
                [A] => 1
                [B] => 1
                [C] => 2
                [D] => No
                [E] => New
                [F] => New
                [G] => 2
                [H] => 2
                [I] => 2
                [A] => 2
                [J] => 2
                [B] => 2
            )

    )

)

我想回复如下：

date      A B C D E F G H I A J B
2014-11-12  1 2 2 No  New New 1 1 1 1 1 1
2014-12-12  1 1 2 No  New New 2 2 2 2 2 2

我怎么做这件事最好的建议是什么。

Answer 1

在这种情况下，您可以使用普通的foreach。至于标题，您可能需要使用array_keys()。例如：

<?php

$array = [ 'total' => 1, 'rows' => [ [ 'date' => '2014-11-12', 'A' => '1', 'B' => '2', 'C' => '2', 'D' => 'No', 'E' => 'New', 'F' => 'New', 'G' => '1', 'H' => '1', 'I' => '1', 'A' => '1', 'J' => '1', 'B' => '1', ], [ 'date' => '2014-12-12', 'A' => '1', 'B' => '1', 'C' => '2', 'D' => 'No', 'E' => 'New', 'F' => 'New', 'G' => '2', 'H' => '2', 'I' => '2', 'A' => '2', 'J' => '2', 'B' => '2', ], ],];
$keys = array_keys(reset($array['rows']));

?>

<table cellpadding="10">
    <thead>
    <tr align="left">
        <?php foreach($keys as $header): ?>
            <th><?php echo $header; ?></th>
        <?php endforeach; ?>
    </tr>
    </thead>
    <tbody>
    <?php foreach($array['rows'] as $row): ?>
        <tr><?php foreach ($row as $value): ?>
            <td><?php echo $value; ?></td>
        <?php endforeach; ?></tr>
    <?php endforeach; ?>
    </tbody>
</table>

Sample Output

以CSV格式打印：

$array = [ 'total' => 1, 'rows' => [ [ 'date' => '2014-11-12', 'A' => '1', 'B' => '2', 'C' => '2', 'D' => 'No', 'E' => 'New', 'F' => 'New', 'G' => '1', 'H' => '1', 'I' => '1', 'A' => '1', 'J' => '1', 'B' => '1', ], [ 'date' => '2014-12-12', 'A' => '1', 'B' => '1', 'C' => '2', 'D' => 'No', 'E' => 'New', 'F' => 'New', 'G' => '2', 'H' => '2', 'I' => '2', 'A' => '2', 'J' => '2', 'B' => '2', ], ],];
$data[] = array_keys(reset($array['rows'])); // push header inside
$data = array_merge($data, $array['rows']); // push values inside

$file = fopen('whatevertname.csv', 'w+');
foreach ($data as $value) {
    fputcsv($file, $value);
}
fclose($file);

假设您正在使用fputcsv()函数编写csv文件，

您应首先使用array_keys()获取所有数组键。您可以从第一个数据行获取它并将其插入新数组（让我们将其命名为'csv_array'）。
您现在应该拥有新数组，第一个数据是字段数组。
然后，您应该循环所有数据并将其添加到'csv_array'。
通过fputcsv（）函数编写。

在使用fputcsv（）

Array
    (
        [0] => Array
            (
                [0] => date
                [1] => A
                [2] => B
                [3] => C
                [4] => D
                [5] => E
                [6] => F
                [7] => G
                [8] => H
                [9] => I
                [10] => A
                [11] => J
                [12] => B
            )
        [1] => Array
            (
                [0] => 2014-12-12
                [1] => 1
                [2] => 2
                [3] => 2
                [4] => No
                [5] => New
                [6] => New
                [7] => 1
                [8] => 1
                [9] => 1
                [10] => 1
                [11] => 1
                [12] => 1
            )

    )

echo多维数组到csv
