日历类实现
1、输出星期
calendar.class.php
1 <?php 2 class Calendar{ 3 4 function out(){//输出表格 5 echo \'<table align="center">\'; 6 $this->weeksList(); //输出星期 7 8 echo \'</table>\'; 9 } 10 private function weeksList(){ 11 12 $week=array(\'日\',\'一\',\'二\',\'三\',\'四\',\'五\',\'六\'); 13 echo \'<tr>\'; 14 for($i=0;$i<count($week);$i++) 15 echo \'<th class="fontb">\'.$week[$i].\'</th>\'; 16 echo \'</tr>\'; 17 } 18 19 20 ?>
index.php
1 <style> //样式 2 table { 3 border:1px solid #050; //边框，050:绿色 4 } 5 .fontb { 6 color:white; 7 background:blue; 8 } 9 10 th { 11 width=30px;height=30px; 12 } 13 </style> 14 <?php 15 include "calendar.class.php"; 16 17 $calendar=new Calendar; 18 $calendar->out(); 19 ?
2、输出日期
calendar.class.php
1 <?php 2 class Calendar{ 3 private $year; 4 private $month; 5 private $start_weekday; // 当月的第一天是周几 6 private $days;//当前月有几天 7 8 function __construct(){ 9 $this->year=date("Y"); 10 $this->month=date("m"); 11 12 $this->start_weekday=date("w",mktime(0,0,0,$this->month,1,$this->year)); 13 $this->days=date("t",mktime(0,0,0,$this->month,1,$this->year)); 14 } 15 16 function out(){//输出表格 17 echo \'<table align="center">\'; 18 $this->weeksList(); 19 $this->daysList(); 20 echo \'</table>\'; 21 } 22 private function weeksList(){ 23 24 $week=array(\'日\',\'一\',\'二\',\'三\',\'四\',\'五\',\'六\'); 25 echo \'<tr>\'; 26 for($i=0;$i<count($week);$i++) 27 echo \'<th class="fontb">\'.$week[$i].\'</th>\'; 28 echo \'</tr>\'; 29 } 30 private function daysList(){ 31 echo \'<tr>\'; 32 for($j=0;$j<$this->start_weekday;$j++) 33 echo \'<td> </td>\'; //输出空格 34 35 for($k=1;$k<=$this->days;$k++){ 36 $j++; 37 if($k==date(\'d\')) //当前天显示颜色 38 echo \'<td class="fontb">\'.$k.\'</td>\'; 39 else 40 echo \'<td>\'.$k.\'</td>\'; 41 if ($j%7==0) 42 echo \'</tr><tr>\'; 43 } 44 echo \'</tr>\'; 45 } 46 } 47 ?>
test.php
1 <style> 2 table { 3 border:1px solid #050; 4 } 5 .fontb { 6 color:white; 7 background:blue; 8 } 9 10 th { 11 width=30px; 12 } 13 td,th { //使显示居中 14 height=30px; 15 text-align:center; 16 } 17 </style> 18 <?php 19 include "calendar.class.php"; 20 21 $calendar=new Calendar; 22 $calendar->out(); 23 ?>
3、
calendar.class.php
1 <?php 2 class Calendar{ 3 private $year; 4 private $month; 5 private $start_weekday; // 当月的第一天是周几 6 private $days;//当前月有几天 7 8 function __construct(){ 9 $this->year=isset($_GET["year"])?htmlspecialchars($_GET["year"]):date("Y"); 10 $this->month=isset($_GET["month"])?htmlspecialchars($_GET["month"]):date("m"); 11 12 $this->start_weekday=date("w",mktime(0,0,0,$this->month,1,$this->year)); 13 $this->days=date("t",mktime(0,0,0,$this->month,1,$this->year)); 14 } 15 16 function out(){//输出表格 17 echo \'<table align="center">\'; 18 $this->chageDate(); 19 $this->weeksList(); 20 $this->daysList(); 21 echo \'</table>\'; 22 } 23 24 private function weeksList(){ 25 26 $week=array(\'日\',\'一\',\'二\',\'三\',\'四\',\'五\',\'六\'); 27 echo \'<tr>\'; 28 for($i=0;$i<count($week);$i++) 29 echo \'<th class="fontb">\'.$week[$i].\'</th>\'; 30 echo \'</tr>\'; 31 } 32 33 private function daysList(){ 34 echo \'<tr>\'; 35 for($j=0;$j<$this->start_weekday;$j++) 36 echo \'<td> </td>\'; //输出空格 37 38 for($k=1;$k<=$this->days;$k++){ 39 $j++; 40 if($k==date(\'d\')) //当前天显示颜色 41 echo \'<td class="fontb">\'.$k.\'</td>\'; 42 else 43 echo \'<td>\'.$k.\'</td>\'; 44 if ($j%7==0) 45 echo \'</tr><tr>\'; 46 } 47 48 //后面几个空格 49 while($j%7!==0){ 50 echo \'<td> </td>\'; 51 $j++; 52 } 53 echo \'</tr>\'; 54 } 55 56 private function prevYear($year,$month){ 57 $year=$year-1; 58 if($year<1970) 59 $year=1970; 60 return "year={$year}&month={$month}"; 61 } 62 private function prevMonth($year,$month){ 63 if($month==1){ 64 $year=$year-1; 65 $month=12; 66 if($year<1970) 67 $year=1970; 68 }else{ 69 $month--; 70 } 71 72 return "year={$year}&month={$month}"; 73 } 74 private function nextYear($year,$month){ 75 $year=$year+1; 76 if($year>2038) 77 $year=2038; 78 return "year={$year}&month={$month}"; 79 } 80 private function nextMonth($year,$month){ 81 if($month=12){ 82 $year=$year+1; 83 $month=1; 84 if($year>2038) 85 $year=2038; 86 }else{ 87 $month++; 88 } 89 return "year={$year}&month={$month}"; 90 } 91 92 private function chageDate(){ 93 echo \'<tr>\'; 94 echo \'<td><a href="?\'.$this->prevYear($this->year,$this->month).\'">\'.\'<<\'.\'</a></td>\'; 95 echo \'<td><a href="?\'.$this->prevMonth($this->year,$this->month).\'">\'.\'<\'.\'</a></td>\'; 96 echo \'<td colspan="3">\'.$this->year.\'年\'.$this->month.\'月\'.\'</td>\'; 97 echo \'<td><a href="?\'.$this->nextMonth($this->year,$this->month).\'">\'.\'>\'.\'</a></td>\'; 98 echo \'<td><a href="?\'.$this->nextYear($this->year,$this->month).\'">\'.\'>>\'.\'</a></td>\'; 99 echo \'</tr>\'; 100 } 101 } 102 ?>
4、增加年月选择下拉列表 *
calendar.calss.php
<?php class Calendar{ private $year; private $month; private $start_weekday; // 当月的第一天是周几 private $days;//当前月有几天 function __construct(){ $this->year=isset($_GET["year"])?htmlspecialchars($_GET["year"]):date("Y"); $this->month=isset($_GET["month"])?htmlspecialchars($_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(){//输出表格 echo \'<table align="center">\'; $this->chageDate("text.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[$i].\'</th>\'; echo \'</tr>\'; } private function daysList(){ echo \'<tr>\'; for($j=0;$j<$this->start_weekday;$j++) echo \'<td> </td>\'; //输出空格 for($k=1;$k<=$this->days;$k++){ $j++; if($k==date(\'d\')) //当前天显示颜色 echo \'<td class="fontb">\'.$k.\'</td>\'; else echo \'<td>\'.$k.\'</td>\'; if ($j%7==0) echo \'</tr><tr>\'; } //后面几个空格 while($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; $month=12; if($year<1970) $year=1970; }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){ $year=$year+1; $month=1; if($year>2038) $year=2038; }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;$sy<=2038;$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">\'; for($sm=1;$sm=12;$sm++){ $selected1= ($sm==$this->month)? "selected" : ""; echo \'<option \'.$selected1.\' value="\'.$sm.\'">\'.$sm.\'</option>\'; } echo \'</select>\'; echo \'</form>\'; echo \'</td>\'; echo \'<td><a href="?\'.$this->nextMonth($this->year,$this->month).\'">\'.\'>\'.\'</a></td>\'; echo \'<td><a href="?\'.$this->nextYear($this->year,$this->month).\'">\'.\'>>\'.\'</a></td>\'; echo \'</tr>\'; } } ?>
test.php
<style> table { border:1px solid #050; } .fontb { color:white; background:blue; } th { width=30px; } td,th { //使显示居中 height=30px; text-align:center; } form { margin:0px; padding:0px; } </style> <?php include "calendar.class.php"; $calendar=new Calendar; $calendar->out(); ?>
