一个实例php mysql模板分页类

<?php教程
/*
 * 模板分页类,源于easp教程的数据库教程分页方法，算是easp分页的的php独立版
 * 支持动态和静态分页方式
 * * page([总记录数=1]，[分页大小=20]，[当前页=1]，[显示页数=6]，[分页参数='page'],[分页链接=当前页面],[是否静态=false])
 * 动态：
 * 简单用法：
 * $page = new page(50);
 * $page->setpager('zjj','<div class="newpager">共有{recordcount} 个商品&nbsp;&nbsp;当前第&nbsp;{pageindex}&nbsp;页&nbsp;/&nbsp;共&nbsp;{pagecount}&nbsp;页&nbsp;分页：&nbsp;{first}{prev}&nbsp;&nbsp;{list}&nbsp;&nbsp;{next}{last}&nbsp;&nbsp;转到&nbsp;{jump}&nbsp;页</div>',array("listlong"=>"6","first"=>"首页","last"=>"尾页","prev"=>"上一页","next"=>"下一页","list"=>"第*页","jump"=>"select"));
 * echo $page->getpager('zjj');
 * 全参数用法：
 * $page = new page(50,20,1,6,'page','prrr.php',false);
 * $page->setpager('zjj','<div class="newpager">共有{recordcount} 个商品&nbsp;&nbsp;当前第&nbsp;{pageindex}&nbsp;页&nbsp;/&nbsp;共&nbsp;{pagecount}&nbsp;页&nbsp;分页：&nbsp;{first}{prev}&nbsp;&nbsp;{list}&nbsp;&nbsp;{next}{last}&nbsp;&nbsp;转到&nbsp;{jump}&nbsp;页</div>',array("listlong"=>"6","first"=>"首页","last"=>"尾页","prev"=>"上一页","next"=>"下一页","list"=>"第*页","jump"=>"select"));
 * echo $page->getpager('zjj');
 * 静态：
 * $page = new page(50,20,1,6,'page','prrr{page}.html',true);
 * $page->setpager('zjj','<div class="newpager">共有{recordcount} 个商品&nbsp;&nbsp;当前第&nbsp;{pageindex}&nbsp;页&nbsp;/&nbsp;共&nbsp;{pagecount}&nbsp;页&nbsp;分页：&nbsp;{first}{prev}&nbsp;&nbsp;{list}&nbsp;&nbsp;{next}{last}&nbsp;&nbsp;转到&nbsp;{jump}&nbsp;页</div>',array("listlong"=>"6","first"=>"首页","last"=>"尾页","prev"=>"上一页","next"=>"下一页","list"=>"第*页","jump"=>"select"));
 * echo $page->getpager('zjj');

ajax只支持utf-8格式，不能支持gb2312编码格式，所以经常遇到gb2312的编码的程序使用ajax就出现乱码，刚找到一种解决方案是

服务器端传送的数据仍是gb2312编码，客户端用js将汉字转变成utf8编码显示在页面

方法一json
一，服务器端json数据用php教程的iconv函数转换：iconv('gb2312', 'utf8', "被转换字符串，输出到浏览器"); 
      客户端获取utf8数据，再转成gb2312：

function gb2utf8(data){//gb编码是，ie通过二进制码utf8->gbk转为中文 
     var glbencode = []; 
     gb2utf8_data = data; 
     execscript("gb2utf8_data = midb(gb2utf8_data, 1)", "vbscript"); 
     var t=escape(gb2utf8_data).replace(/%u/g,"").replace(/(.{2})(.{2})/g|>,"%$2%$1").replace(/%([a-z].)%(.{2})/g|>,"@$1$2"); 
     t=t.split("@"); 
     var i=0,j=t.length,k; 
     while(++i<j)> 
         k=t.substring(0,4); 
         if(!glbencode[k]) { 
             gb2utf8_char = eval("0x"+k); 
             execscript("gb2utf8_char = chr(gb2utf8_char)", "vbscript"); 
             glbencode[k]=escape(gb2utf8_char).substring(1,6); 
         } 
         t=glbencode[k]+t.substring(4); 
     } 
     gb2utf8_data = gb2utf8_char = null; 
     return unescape(t.join("%")); 
}

二，header("content-type", "application/x-www-form-urlencoded; charset=gbk"); //输出头标，设置为gbk编码

三，在ajax请求数据前调用上面的方法指定请求使用的字符集:xmlhttp.setrequestheader( "content-type", "application/x-www-form-urlencoded;charset=gbk");

方案二

<?php
header("content-type: text/html; charset=gb2312");

本款文件上传类，默认是上传单文件的,我们只要修改$inputname ='files'为你的表单名就可以方便的实现批量文件上传了。 $savename = ''保存文件名, $alowexts = array()设置允许上传的类型，$savepath = ''保存路径。

文章利用了二个实例来讲述一下关于php 设置cookie与 读取cookie及cookie删除等处理方法

如果需要更新cookie以让其储存新值，只需要将其原值覆盖即可。因此，即使你已经在之前的页面中刚刚发送cookie，仍可以将你的名字改为"jeff"。
*/

代码如下	复制代码
$y2k = mktime(0,0,0,1,1,2000); setcookie('name', 'jeff', $y2k);

/*
上面是个简单的cookie实例，下面我们来看个复杂的cookie 来作用户登录验证实例代码。
*/

代码如下	复制代码
function verify() {   global $pass;   if($_post['pass'] == $pass || $_cookie['pass'] == md5($pass))   {     cookie(true);     return true;   }   else   {     cookie(false);     return false;   } } function cookie($set = true) {   global $pass;   if($set)     setcookie("pass",md5($pass),time()+3600);   else     setcookie("pass","",time()-3600); }
