writing to a csv with fputcsv

<?php
$list = array
(
"Peter,Griffin,Oslo,Norway",
"Glenn,Quagmire,Oslo,Norway",
);

$file = fopen("contacts.csv","w");

foreach ($list as $line)
  {
  fputcsv($file,explode(',',$line));
  }

fclose($file); ?>

The CSV file will look like this after the code above has been executed:

Peter,Griffin,Oslo,Norway
Glenn,Quagmire,Oslo,Norway
