CSV export in php - csv row as a variable - laravel

Question

I want to export a data into CSV file using PHP Laravel.
I used every row as a variable and add to csv at last. It helps me to create custom CSV file collumn header, so I must follow this rule.
What I have done is this-
$tweets = DB::select(DB::raw($query));
foreach ($tweets as $row)
{
$row = get_object_vars($row);
// iterate over each tweet and add it to the csv
$output .= implode(",",
array(
$row['completion_date'],
$row['site_id'],
$row['country'],
$row['state'],
$row['city'],
$row['active_ipp'],
$row['description_of_project'],
$row['total_excess_furniture']
)
); // append each row
$output .="\n"; //Adding New Line
}
$headers = array(
'Content-Type' => 'text/csv',
'Content-Disposition' => 'attachment;filename="'.Carbon\Carbon::now()->toDateTimeString().'.csv"',
);
return Response::make(rtrim($output, "\n"), 200, $headers);
It is working with some errors.
The errors are, when there is a comma in the object string, it does not work perfectly.
So, I can't use implode I think.
Is there any other solution for adding CSV row as a variable like this?

You can try something along the lines of:
$items = [
[
'field1' => 'string with " quotes',
'field2' => 'string without commas',
],
[
'field1' => 'string without quotes',
'field2' => 'string, with, commas',
],
];
ob_start();
$buffer = fopen('php://output', 'w+');
foreach($items as $item) {
fputcsv($buffer, [
$item['field1'],
$item['field2'],
]);
}
$output = ob_get_clean();
fputcsv will deal with commas or quotes in your variables. Instead of writing the output to a file, you can send the output to a buffer and store it to a variable using ob_start and ob_get_clean.
