How can I referece an array element using for loop?

In the function, it uses foreach loop but I only want to retrieve and print out the 1st 3 events.  I uses these code in for loop but not working.  This is my 1st PHP and trying to apply C# code syntax doesn't work.
for($i=1; $i<=3; $i++) {
                              $event = $eventFeed[i];
                              echo "\t<li>" . $event->title->text .  " (" . $event->id->text . ")\n";
                              echo "\t\t<ul>\n";
                              foreach ($event->when as $when) {
                                echo "\t\t\t<li>Starts: " . $when->startTime . "</li>\n";
                              }
                              echo "\t\t</ul>\n";
                              echo "\t</li>\n";
                          }
function outputCalendar($client) 
{
  $gdataCal = new Zend_Gdata_Calendar($client);
  $eventFeed = $gdataCal->getCalendarEventFeed();
  echo "<ul>\n";
  foreach ($eventFeed as $event) {
    echo "\t<li>" . $event->title->text .  " (" . $event->id->text . ")\n";
    echo "\t\t<ul>\n";
    foreach ($event->when as $when) {
      echo "\t\t\t<li>Starts: " . $when->startTime . "</li>\n";
    }
    echo "\t\t</ul>\n";
    echo "\t</li>\n";
  }
  echo "</ul>\n";
}

your code forgot the $ in $event = $eventFeed[i];

function outputCalendar($client)
{
  $gdataCal = new Zend_Gdata_Calendar($client);
  $eventFeed = $gdataCal->getCalendarEventFeed();
  echo "<ul>\n";
  for ($i = 0; $i < 3; $i++) {
    $event = $eventFeed[$i];
    echo "\t<li>" . $event->title->text .  " (" . $event->id->text . ")\n";
    echo "\t\t<ul>\n";
    foreach ($event->when as $when) {
      echo "\t\t\t<li>Starts: " . $when->startTime . "</li>\n";
    }
    echo "\t\t</ul>\n";
    echo "\t</li>\n";
  }
  echo "</ul>\n";
}

Ah, got that.  Does arrary index starts with 0 in PHP array?  Also, if I want to break out of the for looop when $event is assign a null can I code it like:
function outputCalendar($client)
{
  $gdataCal = new Zend_Gdata_Calendar($client);
  $eventFeed = $gdataCal->getCalendarEventFeed();
  echo "<ul>\n";
  for ($i = 0; $i < 3; $i++) {
    $event = $eventFeed[$i];
if($event == null)
   break;
    echo "\t<li>" . $event->title->text .  " (" . $event->id->text . ")\n";
    echo "\t\t<ul>\n";
    foreach ($event->when as $when) {
      echo "\t\t\t<li>Starts: " . $when->startTime . "</li>\n";
    }
    echo "\t\t</ul>\n";
    echo "\t</li>\n";
  }
  echo "</ul>\n";
}
