分享一例php新闻内容的分页类，自己写的，应该还不错吧，呵呵，感兴趣的朋友可以参考下，用来研究php分页也是不...

本节内容：
PHP新闻分页类

将以下内容，保存为文件：content2page.class.php。

代码：

复制代码代码示例:

<?php
/***
*类名：content2page.class.php
*描述：用于自动生成新闻静态页，手动添加分页功能，自动生成页码
*整理：
使用示例：
$con2page = new Content2Page;
$con2page->FileName = ""; //生成静态文件名
$con2page->FileDir = "html/"; //生成静态页面存放的目录文件夹，若不为空则要在末尾加“/”
$con2page->TemplateName = ""; //模班文件名
$con2page->Content = ""; //新闻内容,一般用POST或GET传递
$con2page->Content2Html();
**/
class Content2Page
{
var $FileName = "test";//生成静态页面的文件名，默认为test
var $FileDir = "";//生成静态页面存放的目录文件夹，若不为空则要在末尾加“/”
var $TemplateName = "template.html";//调用模班页面名称,默认为template.html
var $NewsPage = "";//新闻分页
var $Content = "";//新闻内容
var $SplitSymbol = "*分页符*";//内容分页符,默认为“*分页符*”
var $NowPage = "";//当前页面
var $CountPage = "";//总分页数

/***
 Function: Content2Html()
 Description: 用来将新闻内容分页输出
 Calls: ReadFromFile(),Write2File(),GetPageCount()
