<?php
function build_calendar($month,$year) {
// 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'> </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'> </td>";
}
$calendar .= "</tr>";
$calendar .= "</table>";
return $calendar;
}
//调用方法
echo build_calendar(05,2016);
?>
运行结果如下图所示：
