Try this it is working

$.ajax({
  type: "POST",
  url: "http://localhost/export/some.php",
  data: { dataString: "hi" },
  cache: false,
  success: function(data){
    alert(data);
    this.openDestinationURL();    
  }
});

here is the php file

<?php
header('Content-Type: application/excel');
header('Content-Disposition: attachment; filename="sample.csv"');
$data =$_POST["dataString"];

$fp = fopen('php://output', 'w');//set the path
fputcsv($fp, $data);
fclose($fp);
?>

Since you're sending data: { dataString: "hi" } , the actual POST data will be:

if(isset($_POST['dataString'])){
  print $_POST['dataString'];
}

Also use isset().

As for your AJAX:

  $.ajax({
      type: "POST",
      url: "http://localhost/export/some.php",
      data: { dataString: "hi" },
      cache: false,
      success: function(result){
          alert(result);
          this.openDestinationURL();
      }
  });

Send data as multidimensional array

$.post('http://localhost/export/some.php', 
    {data: [["aaa","bbb","ccc","dddd"],["123","456","789"],["aaa","bbb"]]}, 
    function(){
        alert('saved');
    }
);

On php side just save to file

$output = fopen('path to csv file', 'w');
foreach ($_POST['data'] as $row) {
    fputcsv($output, $row, ';');
}
fclose($output);
