Code Snippet:

<?php

function build_calendar($month,$year,$dateArray) {

// Create array containing abbreviations of days of week.
$daysOfWeek = array('S','M','T','W','T','F','S');

// What is the first day of the month in question?
$firstDayOfMonth = mktime(0,0,0,$month,1,$year);

// How many days does this month contain?
$numberDays = date('t',$firstDayOfMonth);

// Retrieve some information about the first day of the
// month in question.
$dateComponents = getdate($firstDayOfMonth);

// What is the name of the month in question?
$monthName = $dateComponents['month'];

// What is the index value (0-6) of the first day of the
// month in question.
$dayOfWeek = $dateComponents['wday'];

// Create the table tag opener and day headers

$calendar = "<table class='calendar'>";
$calendar .= "<caption>$monthName $year</caption>";
$calendar .= "<tr>";

// Create the calendar headers

foreach($daysOfWeek as $day) {
$calendar .= "<th class='header'>$day</th>";
}

// Create the rest of the calendar

// Initiate the day counter, starting with the 1st.

$currentDay = 1;

$calendar .= "</tr><tr>";

// The variable $dayOfWeek is used to
// ensure that the calendar
// display consists of exactly 7 columns.

if ($dayOfWeek > 0) {
$calendar .= "<td colspan='$dayOfWeek'>&nbsp;</td>";
}

$month = str_pad($month, 2, "0", STR_PAD_LEFT);

while ($currentDay <= $numberDays) {

// Seventh column (Saturday) reached. Start a new row.

if ($dayOfWeek == 7) {

$dayOfWeek = 0;
$calendar .= "</tr><tr>";

}

$currentDayRel = str_pad($currentDay, 2, "0", STR_PAD_LEFT);

$date = "$year-$month-$currentDayRel";

$calendar .= "<td class='day' rel='$date'>$currentDay</td>";

// Increment counters

$currentDay++;
$dayOfWeek++;

}

// Complete the row of the last week in month, if necessary

if ($dayOfWeek != 7) {

$remainingDays = 7 - $dayOfWeek;
$calendar .= "<td colspan='$remainingDays'>&nbsp;</td>";

}

$calendar .= "</tr>";

$calendar .= "</table>";

return $calendar;

}
