Create CSV from multidimensional array with fputcsv

Question

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
            


        

Answer 1

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);
}

In each iteration it would create an array like this:

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