Creating Web Calendars With The PEAR Calendar Class
Need a quick-and-dirty Web calendar? Look no further!

| Changing The Decor |

The Calendar package also includes what it calls "decorators". No, these aren't the guys who attempt to re-arrange your living room, but a set of tools to help you create more user-friendly and usable calendars. The one you're likely to use fairly often is called the Textual decorator, which lets you print names instead of numbers for months and weekdays. Here's an example:

// include classes

// create and build month data structure
// containing day objects
// classified by week
$month =& new Calendar_Month_Weekdays(2005, 6);

// create decorator
$deco =& new Calendar_Decorator_Textual($month);

// print month and year
echo "<tr><td colspan=7 align=center>" . $deco->thisMonthName('short') . " " . $deco->thisYear() . "</td></tr>";

// print day names
$dayNames = $deco->orderedWeekdays('two');
echo "<tr>";
foreach ($dayNames as $name) {
    echo "<td>$name</td>";
echo "</tr>";

// iterate over days
// display as weekly calendar
while ($day = $month->fetch()) {
    // if first day of week
    // start a new row
    if ($day->isFirst()) {
        echo "<tr>";

    // if this day does not belong to this month
    // print empty spaces
    if ($day->isEmpty()) {
        echo "<td>&nbsp;</td>";
    // else print the day number
    } else {
        echo "<td align=right>" . $day->thisDay() . "</td>";

    // if last day
    // end row
    if ($day->isLast()) {
        echo "</tr>";

In this case, an instance of the Calendar_Decorator_Textual class is initialized with a Month() object. This decorator object is then used to print month names and weekday names, via its thisMonthName() and orderedWeekdays() methods respectively. Here's what the result looks like:

Notice that this script differs from previous ones, in that it generates the calendar using HTML table cells. I've done this mostly because it provides me with the opportunity to showcase another method of the Day() object, the isLast() method. This method does the opposite of the isFirst() method discussed earlier, indicating whether the particular day falls at the end of the week. If isLast() returns true, it means it's time to end the current table row with a </tr>.
