从fputcsv多维数组创建CSV [英] Create CSV from multidimensional array with fputcsv

问题描述

我试图得到一个多维数组到CSV文件中。阵列中的数据是这样：

I'm trying to get a multidimensional array into a csv file. data in the array is as such:

Array
(
 [0] => Array
    (
        [product_id] => 1111
        [name] => Alcatel One Touch Idol 2
        [keyword] => alcatel-one-touch-idol-2
        [options] => Array
            (
                [0] => Array
                    (
                        [price] => 54.0000
                    )

                [1] => Array
                    (
                        [price] => 42.0000
                    )

                [2] => Array
                    (
                        [price] => 10.0000
                    )

                [3] => Array
                    (
                        [price] => 
                    )

                [4] => Array
                    (
                        [price] => 
                    )

                [5] => Array
                    (
                        [price] => 
                    )

                [6] => Array
                    (
                        [price] => 
                    )

                [7] => Array
                    (
                        [price] => 
                    )

                [8] => Array
                    (
                        [price] => 
                    )

                [9] => Array
                    (
                        [price] => 
                    )

            )

    )

[1] => Array
    (...... etc)

我得到的所有顶级的数据，但一旦到达options数组，我得到阵列字符串转换错误。所以，我有两个问题，我首先需要明白为什么我收到此错误，然后我需要fputcsv所有这些信息对每个产品一行。

I get all of the top level data, but then once it reaches the options array, i get Array to string conversion errors. So i have two issue, i firstly need to see why i am getting this error, and then i need to fputcsv all of this information on one line per product.

到目前为止，我有这个解析阵列到CSV：

So far i have this to parse the array into a csv:

$output = fopen("php://output",'w') or die("Can't open php://output");
            header("Content-Type:application/csv"); 
            header("Content-  Disposition:attachment;filename=product_catalog.csv"); 
            $first_line = explode(",", $first_line);
            fputcsv($output, $first_line);
            foreach($csv as $file) {
                fputcsv($output, $file);
            }
            fclose($output) or die("Can't close php://output");

如果有人可以帮助我，我会很AP preciate这一点。
问候。

If anyone could help me i'd really appreciate that. regards.

推荐答案

我会建议先压扁每个数组：

I would suggest to flatten each array first:

foreach ($csv as $file) {
    $result = [];
    array_walk_recursive($file, function($item) use (&$result) {
        $result[] = $item;
    });
    fputcsv($output, $result);
}

在每次迭代中，将创建一个这样的数组：

In each iteration it would create an array like this:

[1111, 'Alcatel One Touch Idol 2', 'alcatel-one-touch-idol-2', 54, 42, ...]
