功能很简单，只是使用 PHP 读取文本(TXT)文件并分页显示


    <?php //----------------you should save this file as m.php----------------
      session_start(); 
      if (empty($page)) {$page=1;}
      if (isset($_GET['page'])==TRUE) {$page=$_GET['page']; }
    ?> 
    <html> 
    <head> 
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> 
    <title>Read Result</title> 
    <style type="text/css"> 
    <!-- 
    .STYLE1 {font-size: 12px} 
    .STYLE2 {font-size: 18px} 
    --> 
    </style> 
    </head> 
    <body> 
    <table width="100%" bgcolor="#CCCCCC"> 
    <tr> 
    <td > 
    <?php 
    if($page){ 
    $counter=file_get_contents("example.txt"); //-------read the file into a string.-------
    $length=strlen($counter); 
    $page_count=ceil($length/5000); 

    function msubstr($str,$start,$len){ 
      $strlength=$start+$len; 
      $tmpstr="";
      for($i=0;$i<$strlength;$i++) { 
      if(ord(substr($str,$i,1))==0x0a) { 
        $tmpstr.='<br />';
      }
      if(ord(substr($str,$i,1))>0xa0) { 
        $tmpstr.=substr($str,$i,2); 
        $i++; 
      }
      else{ 
        $tmpstr.=substr($str,$i,1); } 
      } 
      return $tmpstr; 
    } 
    //--------------------------截取中文字符串-------------------------- 
    $c=msubstr($counter,0,($page-1)*5000); 
    $c1=msubstr($counter,0,$page*5000); 
    echo substr($c1,strlen($c),strlen($c1)-strlen($c)); 
    }?> 
    </td> 
    </tr> 
    </table> 

    <table width="100%" bgcolor="#cccccc"> 
    <tr>

    <span class="STYLE1">

    echo "<a href=m.php?page=1>首页</a> ";

    } 
    if($page<$page_count){ 
      echo "<a href=m.php?page=".($page+1).">下一页</a> "; 
    }
