Answer 1

First make data as a String with comma as the delimiter (separated with ","). Something like this

$CSV_string="No,Date,Email,Sender Name,Sender Email \n"; //making string, So "\n" is used for newLine

$rand = rand(1,50); //Make a random int number between 1 to 50.
$file ="export/export".$rand.".csv"; //For avoiding cache in the client and on the server 
                                     //side it is recommended that the file name be different.

file_put_contents($file,$CSV_string);

/* Or try this code if $CSV_string is an array
    fh =fopen($file, 'w');
    fputcsv($fh , $CSV_string , ","  , "\n" ); // "," is delimiter // "\n" is new line.
    fclose($fh);
