本文实例讲述了PHP简单创建日历的方法。分享给大家供大家参考，具体如下：

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 = "";

$calendar .= "

";

$calendar .= "

";

// Create the calendar headers

foreach($daysOfWeek as $day) {

$calendar .= "

";

}

// Create the rest of the calendar

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

$currentDay = 1;

$calendar .= "

";

// The variable $dayOfWeek is used to

// ensure that the calendar

// display consists of exactly 7 columns.

if ($dayOfWeek > 0) {

$calendar .= "

";

}

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

while ($currentDay <= $numberDays) {

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

if ($dayOfWeek == 7) {

$dayOfWeek = 0;

$calendar .= "

";

}

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

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

$calendar .= "

";

// Increment counters

$currentDay++;

$dayOfWeek++;

}

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

if ($dayOfWeek != 7) {

$remainingDays = 7 - $dayOfWeek;

$calendar .= "

";

}

$calendar .= "

";

$calendar .= "

$monthName $year

$day
$currentDay

";

return $calendar;

}

//调用方法

echo build_calendar(05,2016);

?>

希望本文所述对大家PHP程序设计有所帮助。
