如何用php做日历
具体代码如下：
?php
$ch = curl_init();
$timeout = 5;
curl_setopt ($ch, CURLOPT_URL, '');
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$file_contents = curl_exec($ch);
curl_close($ch);
echo $file_contents;

PHP 独特的语法混合了C、Java、Perl以及PHP自创的语法。
它可以比CGI或者Perl更快速地执行动态网页。用PHP做出的动态页面与其他的编程语言相比，PHP是将程序嵌入到HTML（标准通用标记语言下的一个应用）文档中去执行，
执行效率比完全生成HTML标记的CGI要高许多；
PHP还可以执行编译后代码，编译可以达到加密和优化代码运行，使代码运行更快。
如何用PHP制作日历
calendar.class.php
代码如下:
?php
class Calendar {
private $year; //当前的年
private $month; //当前的月
private $start_weekday; //当月的第一天对应的是周几
private $days; //当前月一共多少天
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; $icount($week); $i++)
echo 'th class="fontb"'.$week[$i].'/th';
echo '/tr';
}
private function daysList(){
echo 'tr';
//输出空格(当前一月第一天前面要空出来)
for($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($j%7==0)
echo '/trtr';
}
//后面几个空格
while($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){

}else{

}

$year = $year + 1;

echo 'option '.$selected.' value="'.$sy.'"'.$sy.'/option';
}

echo 'tda href="?'.$this-nextMonth($this-year, $this-month).'"'.''.'/a/td';
echo '/tr';
}
}
?
test.php
代码如下:
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();

PHP如何生成一个指定年份一整年的日历
从你的描述看来，只需要知道指定年份的每个月的天数和每天对应的周次即可。
PHP中 Calendar 函数可以实现第一步：
int cal_days_in_month ( int $calendar , int $month , int $year )
剩下的就是写循环遍历所有月，按月生成日历了。
