两个php日期控制类实例_php技巧

本文实例讲述了两个php日期控制类。分享给大家供大家参考。具体分析如下：

由于工作需要我找了二个时间日期控制,这个不用js只要php实现的,因为要带参考查询操作,感兴趣的朋友可以参考一下,我自己用的是第二个,所以第二个己作了修改.

实例一,代码如下:
代码如下:<?php
class Calendar
{
var $month;
var $year;

function __construct($year,$month)
{
$this->year=$year;
$this->month=$month;
}

function endday()
{
$daydate=date("d",mktime(0,0,0,$this->month,35,$this->year));
$endday=35-$daydate;
return $endday;
}

function oneday_week()
{
$oneday_week=date("w",mktime(0,0,0,$this->month,1,$this->year));
return $oneday_week;
}

function title_link()
{
if(!isset($this->month) && !isset($this->year))
{
$this->year = date("Y");
$this->month = date("m");
}

$lastmonth=$this->month-1;
$nextmonth=$this->month+1;
$lastyear=$this->year;
$nextyear=$this->year;

if($this->month <= 1)
{
$lastmonth=12;
$nextmonth=$this->month+1;
$lastyear=$this->year-1;
$nextyear=$this->year;
}
elseif ($this->month >= 12)
{
$lastmonth=$this->month-1;
$nextmonth=1;
$lastyear=$this->year;
$nextyear=$this->year+1;
}

$str ="<<<";
$str.="".$this->year."--".$this->month."";
$str.=">>>";
return $str;
}

function Show_Calendar()
{
echo "

".$this->title_link()."";
$weekarray=array("日","一","二","三","四","五","六");

for($k=0;$k<=6;$k++)
{
echo "";
}
echo "";

for($i=0;$i<=5;$i++)
{
echo "";
for($j=1;$j<=7;$j++)
{
$math=( $j - $this->oneday_week() ) + 7 * $i;

echo "";
}
echo "";
}
echo "

".$weekarray[$k]."

"; if($math <= $this->endday() and $math>=1) { echo $math; } echo "

";
}
}
$calendar=new Calendar($_GET['year'],$_GET['month']);
$calendar->month=$_GET['month'];
$calendar->year=$_GET['year'];
$calendar->Show_Calendar();
?>
实例二,代码如下:
代码如下:<?php
header("content-type:text/html;charset=utf-8");
?>




<?php
if(!emptyempty($_GET)){
$year = isset($_GET['year'])?$_GET['year']:date('y');
$month = isset($_GET['month'])?$_GET['month']:date('m');
$day = isset($_GET['day'])?$_GET['day']:date('d');
}
if(emptyempty($year)){
$year = date('Y');
}
if(emptyempty($month)){
$month = date('m');
}

if(emptyempty($month)){
$days = date('d');
}

$start_weekday = date('w',mktime(0,0,0,$month,1,$year));
//echo $start_weekday;
$days = date('t',mktime(0,0,0,$month,1,$year));
//echo $days;
$week = array('日','一','二','三','四','五','六');
$i = 0;
$k = 1;
$j = 0;
echo '';
echo '';
echo '';
for($i = 0;$i < 7;$i++){
echo '';
}
echo '';
echo '';
for($j = 0;$j < $start_weekday;$j++){
echo '';
}
while($k <= $days){
if($k == $day){
echo '';
}else{
echo '';
}
if(($j+1) % 7 == 0){
echo '';
}
$j++;
$k++;
}
while($j % 7 != 0){
echo '';
$j++;
}
echo '';

echo '';
echo "';
echo "';
echo '';
echo "';
echo "';
echo '';
echo '

'.$year.'年'.$month.'月'.'
'.$week[$i].'
'.$j.'	'.$k.'	'.$k.'
'.$j.'
".'<<'.'	".'<'.'	'; echo ''; echo '			".'>>'.'	".'>'.'

';

function lastYear($year,$month){
$year = $year-1;
return "year=$year&month=$month";
}
function lastMonth($year,$month){
if($month == 1){
$year = $year -1;
$month = 12;
}else{
$month--;
}
return "year=$year&month=$month";
}
function nextYear($year,$month){
$year = $year+1;
return "year=$year&month=$month";
}
function nextMonth($year,$month){
if($month == 12){
$year = $year +1;
$month = 1;
}else {
$month++;
}
return "year=$year&month=$month";
}

?>
