php 为数组制作 csv 文件

我有一个数组。当我使用时print_r($output)。我得到这样的数组

array(
    [0] => Array
            (
                [listing_id] => 14
                [category_id] => Modern Australian
                [listing_name] => Boatshed Restaurant
                [image_name] => krish_logo.png
                [address] => 2, Thrower Drive
                [phone] => 07 5534 3888
                [introduction_text] =>

                [licenced] => 0
                [highchair] => 0
                [dress_code] => 

            )
    [1] => Array
            (
                [listing_id] => 13
                [category_id] => Indian,Restaurant,Take-away
                [listing_name] => Krish Indian Cuisine - Varsity Lakes
                [image_name] => krish_logo.png

                [licenced] => 0
                [highchair] => 1
                [dress_code] => Casual



            )
    [2] => Array
            (
                [listing_id] => 12
                [category_id] => Steak
                [listing_name] => Outback Jacks Bar & Grill - Southport

                [payment_types] => 
                [open_days] => 
                [licenced] => 0
                [highchair] => 0
                [dress_code] => 

            )

我想将其导出到 csv 文件。为此我编写了这样的代码

$fichier = 'file.csv';
 header( "Content-Type: text/csv;charset=utf-8" );
 header( "Content-Disposition: attachment;filename=\"$fichier\"" );
 header("Pragma: no-cache");
 header("Expires: 0");

 $fp= fopen('php://output', 'w');

 foreach ($output as $fields) 
 {
    fputcsv($fp, $fields);
 }
 fclose($fp);
 exit();

但在这里我得到了文件，但当我打开文件时，它只显示 array()。那么有人可以告诉我如何获取csv中的数据吗？任何帮助和建议都将非常感激。谢谢

您的数组实际上对 CSV 并不友好，因为它是多维的。

要放入 CSV，您需要将 $output 的每个元素转换为一维数组：

foreach ($output as $fields) {

   $csvrec = array(
        'listing_id' => $fields['listing_id'],
        'category_id' => $fields['category_id'], 
   // etc... etc...
   // down to...
        'parking' => $fields['dinning_details']['parking'],
        'byo_info' => $fields['dinning_details']['byo_info'],
        'indoor' => $fields['dinning_details']['capacity']['indoor'],
   // etc.. etc...
   );

   fputcsv($fp, $csvrec);
}
