look on the file_get_contents function

<?php
$csv = file_get_contents('http://www.google.com/trends/viz?q=london,+paris&date=all&geo=all&graph=all_csv&sort=0&sa=N');    
echo $csv;
?>

$query   = 'london, paris';
$csvFile = 'http://www.google.com/trends/viz?q='.urlencode($query).'&date=all&geo=all&graph=all_csv&sort=0&sa=N';

file_put_contents(file_get_contents($link), 
                  str_replace(array(',', ' ') '-', $query).'.cvs');
