使用php制作的日歷
這篇文章主要介紹了使用php制作的日歷，下面有效果圖，大家參考使用吧
calendar.class.php
代碼如下:
<?php
class Calendar {
private $year; //當前的年
private $month; //當前的月
private $start_weekday; //當月的第一天對應的是周幾
private $days; //當前月一共多少天
function __construct(){
$this->year=isset($_GET["year"]) ? $_GET["year"] : date("Y");
$this->month=isset($_GET["month"]) ? $_GET["month"] : date("m");
$this->start_weekday=date("w", mktime(0, 0, 0, $this->month, 1, $this->year));
$this->days=date("t", mktime(0, 0, 0, $this->month, 1, $this->year));
}
function out(){
echo '<table align="center">';
$this->chageDate("test.php");
$this->weeksList();
$this->daysList();
echo '</table>';
}
private function weeksList(){
$week=array('日','一','二','三','四','五','六');
echo '<tr>';
for($i=0; $i<count($week); $i++)
echo '<th class="fontb">'.$week[$i].'</th>';
echo '</tr>';
}
private function daysList(){
echo '<tr>';
//輸出空格(當前一月第一天前面要空出來)
for($j=0; $j<$this->start_weekday; $j++)
echo '<td> </td>';
for($k=1; $k<=$this->days; $k++){
$j++;
if($k==date('d'))
echo '<td class="fontb">'.$k.'</td>';
else
echo '<td>'.$k.'</td>';
if($j%7==0)
echo '</tr><tr>';
}
//後面幾個空格
while($j%7!==0){
echo '<td> </td>';
$j++;
}
echo '</tr>';
}
private function prevYear($year, $month){
$year=$year-1;
if($year < 1970)
$year = 1970;
return "year={$year}&month={$month}";
}
private function prevMonth($year, $month){
if($month == 1) {
$year = $year -1;
if($year < 1970)
$year = 1970;
$month=12;
}else{
$month--;
}
return "year={$year}&month={$month}";
}
private function nextYear($year, $month){
$year = $year + 1;
if($year > 2038)
$year = 2038;
return "year={$year}&month={$month}";
}
private function nextMonth($year, $month){
if($month==12){
$year++;
if($year > 2100)
$year=2100;
$month=1;
}else{
$month++;
}
return "year={$year}&month={$month}";
}
private function chageDate($url=""){
echo '<tr>';
echo '<td><a href="?'.$this->prevYear($this->year, $this->month).'">'.'<<'.'</a></td>';
echo '<td><a href="?'.$this->prevMonth($this->year, $this->month).'">'.'<'.'</a></td>';
echo '<td colspan="3">';
echo '<form>';
echo '<select name="year" onchange="window.location=''.$url.'?year='+this.options[selectedIndex].value+'&month='.$this->month.''">';
for($sy=1970; $sy <= 2100; $sy++){
$selected = ($sy==$this->year) ? "selected" : "";
echo '<option '.$selected.' value="'.$sy.'">'.$sy.'</option>';
}
echo '</select>';
echo '<select name="month" onchange="window.location=''.$url.'?year='.$this->year.'&month='+this.options[selectedIndex].value">';

echo '<td><a href="?'.$this->nextMonth($this->year, $this->month).'">'.'>'.'</a></td>';
echo '</tr>';
}
}
?>
test.php
代碼如下:
<style>
table {
border:1px solid #050;
}
.fontb {
color:white;
background:blue;
}
th {
width:30px;
}
td,th {
height:30px;
text-align:center;
}
form {
margin:0px;
padding:0px;
}
</style>
<?php
include "calendar.class.php";
$calendar=new Calendar;
$calendar->out();
?>
