PHP如何实现简单日历类编写？本篇文章小编给大家分享一下PHP实现简单日历类编写代码，小编觉得挺不错的，现在分享给大家供大家参考，有需要的小伙伴们可以来看看。

代码如下：

calendar.class.php

year = isset($_GET['year'])?$_GET['year']:date("Y");

$this->month = isset($_GET["month"])?$_GET["month"]:date("m");

$this->first_week = date("w", mktime(0, 0 ,0, $this->month, 1, $this->year));

$this->day = date("t", mktime(0, 0 ,0, $this->month, 1, $this->year));

}

function showCalendar() {

// echo $this->year."年".$this->month."月".$this->first_week."天".$this->day;

echo ""; //用表格输出

$this->chageDate("index.php"); //用于用户调整年月份

$this->weekList();//显示星期

$this->dayList(); //显示天数

echo "";

}

//1、显示星期

private function weekList() {

$week = array("日","一","二","三","四","五","六");

echo "

";

for ($i = 0; $i < count($week); $i++) {

echo "".$week[$i]."";

}

echo "";

}

//2.显示天数

private function dayList() {

$color = "#2ca50c";

echo "

";

for ($i = 0; $i < $this->first_week; $i++) { //输出空格，弥补当前月空缺部分

echo "";

}

for ($k = 1; $i <= $this->day; $k++) {

$i++;

if ($k == date("d")) echo "".$k.""; //是今天，加效果

else echo "".$k."";

if ($i % 7 == 0) {

echo "

"; //每7天一次换行

if ($i % 2 == 0) $color = "#2ca50c";

else $color = "#9ddb27"; //实现各行换色的效果

}

}

while ($i % 7 != 0) { //将剩余的空格补完

echo "";

$i++;

}

echo "";

}

//3、用于用户调整天数

private function chageDate($url="index.php") {

echo "

";

echo "".$this->year."年".$this->month."月";

echo "";

echo "

";

echo "";

echo 'month.'\'">';

for ($year = 2038; $year >= 1970; $year--) {

$selected = ($year == $this->year)?"selected":"";

echo ''.$year.'';

//echo ''.$year.'';

}

echo "";

echo 'year.'&month=\'+this.options[selectedIndex].value">';

for($month=1;$month <= 12;$month++){

$selected1 = ($month == $this->month) ? "selected" : "";

echo ''.$month.'';

}

echo '';

echo "";

echo ""."".">>"."";

echo ""."".">"."";

echo "";

}

private function prevYear($year, $month) { //获取上一年的数据

$year--;

if ($year < 1970) $year = 1970;

return "year={$year}&month={$month}";

}

private function prevMonth($year, $month) {

if ($month == 1) {

$year--;

if ($year < 1970) $year = 1970;

$month = 12;

}else $month--;

return "year={$year}&month={$month}";

}

private function nextYear($year, $month) { //获取上一年的数据

$year++;

if ($year > 2038) $year = 2038;

return "year={$year}&month={$month}";

}

private function nextMonth($year, $month) {

if ($month == 12) {

$year++;

if ($year > 2038) $year = 2038;

$month = 1;

}else $month++;

return "year={$year}&month={$month}";

}

}
