Converting comma-separated API response to CSV - php

Question

I am running an API, the response of this API is returning response in comma separated values.
I am returning response in $result.
Response:
lmd_id,status,title,description,code,categories,store,url,link,start_date,expiry_date,coupon_type 106864,new,"Gift Vouchers worth ₹2000 # for just ₹999","Get it for just ₹999",,"Gift Items","ABC Company",http://example1.com,http://example2.com,"2016-04-07 00:00:00","2016-05-01 00:00:00",sale
Below are the headers in response:
lmd_id,status,title,description,code,categories,store,url,link,start_date,expiry_date,coupon_type
Code I have tried:
function str_putcsv($result) {
# Generate CSV data from array
$fh = fopen('php://temp', 'rw'); # don't create a file, attempt
# to use memory instead
# write out the headers
fputcsv($fh, array_keys(current($result)));
# write out the data
foreach ( $result as $row ) {
fputcsv($fh, $row);
}
rewind($fh);
$csv = stream_get_contents($fh);
fclose($fh);
return $csv;
}
With the code above I am not able to find where this code is generating CSV.
Another code:
$fp = fopen('data.csv', 'w');
foreach($data as $line){
$val = explode(",",$line);
fputcsv($fp, $val);
}
fclose($fp);
Above code is generating file on FTP but there is no data in it. It is generating blank CSV.
I want to convert this response into CSV file and put it on a FTP or in the same directory.

You can just put everything in an array. And use int fputcsv ( resource $handle , array $fields [, string $delimiter = "," [, string $enclosure = '"' [, string $escape_char = "\" ]]] )
Example from php.net:
$list = array (
array('aaa', 'bbb', 'ccc', 'dddd'),
array('123', '456', '789'),
array('"aaa"', '"bbb"')
);
$fp = fopen('path/to/file.csv', 'w');
foreach ($list as $fields) {
fputcsv($fp, $fields);
}
fclose($fp);
