Horizontal calendar using PHP - calendar

Question

You can see what I am trying to make here http://perthurbanist.com/website/calendarloader.php. Basically it is a horizontal calendar and you will use arrows to move. What I want to do is have the code display all the months horizontally along with all the days (starting from the current month and day). I know how to get the current day using the date function but I don't know how to make the calendar start at that date. I also want it to load lots of months (maybe 2-3 years worth). How do I do those two things.
<?php
$showday = date("j");
$displaymonth = date("M");
$showmonth = date("n");
$showyear = date("Y");
$day_count = cal_days_in_month(CAL_GREGORIAN, $showmonth, $showyear);
echo '<ul class="calendarnavigation">';
echo '<li class="month">' . $displaymonth . '</li>';
for($i=1; $i<= $day_count; $i++) {
echo '<li>' . $i . '</li>';
}
echo '</div>';
?>

If you know (or are able to calculate how far ahead you want to go in days you could try this:
for($i=0; $i<$numberOfDays; $i++)
{
$timestamp=mktime(0,0,0,date("m"),date("d")+$i,date("Y"));
$day=date("d", $timestamp);
$month=date("m", $timestamp);
$year=date("Y", $timestamp);
...Your display stuff here...
}
On each iteration of the loop the $timestamp will advance one day and using it in your date functions will give you the information about the date that you need to create your display.
Maybe in your case you can use
echo '<ul class="calendarnavigation">';
for($i=0; $i<$numberOfDays; $i++)
{
$timestamp=mktime(0,0,0,date("m"),date("d")+$i,date("Y"));
$showday=date("j", $timestamp);
$displaymonth=date("M", $timestamp);
$showmonth=date("n", $timestamp);
$showyear=date("Y", $timestamp);
if($showday=="1")
{
echo '<li>'.$displaymonth.'</li>';
}
echo '<li>'.$showday.'</li>';
}
echo '</ul>';
