php make csv file for the array

问题

I have an array. When I am using print_r($output). I am getting the array like this

array(
    [0] => Array
            (
                [listing_id] => 14
                [category_id] => Modern Australian

                [highchair] => 0
                [dress_code] => 

            )
    [1] => Array
            (
                [listing_id] => 13
                [category_id] => Indian,Restaurant,Take-away

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



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

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

            )                

)

I want to export this to a csv file. So for that I made my code like this

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

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

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

But here I am getting the file but when I am opening the file it is showing only array(). So can someone tell me how to get the data in csv? Any help and suggestions will be really appreciable. Thanks

Your array isn't really CSV friendly as it is multi-dimensional.

To put into CSV, you need to convert each element of $output to a one-dimensional array:

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);
}

When passing a nested array to fputcsv, the inner array will show up as 'Array'. You should first flatten your array or format it in a way that corresponds to your desired CSV format.
