drupal cron for multiple sites

There are times when we have multiple site to maintain for our drupal based websites.

One way to do it is by doing a shell script.

But i would prefer to do it using php script instead:

runcron.php

------------------------

$aSites = array(

"http://xyz.com/cron.php",

"http://example.com/cron.php"

);

foreach( $aSites as $sSite ):

$sContent = file_get_contents($sSite);

echo "Retrieved: " . $sSite . "\r\n
";

echo substr($sContent,0, 100) . "...\r\n
";

endforeach;

-------------------

And setup the cron in cpanel:

php [path_to_your_php]/runcron.php

etc.: php /home/example.com/public_html/mydrupal/runcron.php > /dev/null

Hope this is helpful :)
