How to return windows scheduled task list with php

I need a what for PHP to return all of Windows' (XP) Scheduled Tasks - is this possible? I'm creating a scheduling script and the user needs to be able to view what time slots are 开发者_StackOverflow中文版already occupied.

EDIT

I just ran a test my self and this worked. 32-bit Windows, Zend Server

$com = new com("Schedule.Service");
$com->Connect();
$oFolder = $com->GetFolder("\\");
$oCollection = $oFolder->GetTasks(0);
print "Count: " . $oCollection->Count . "n";
for ($i = 1; $i <= $oCollection->Count; $i++)
{
      echo $oCollection ->Item($i)->Name ;
}
