    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){ 
$counter=file_get_contents("example.txt"); //读取txt文件内容到$counter
$length=strlen($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 width="100%"  bgcolor="#cccccc"> 
<tr> 
<td width="42%" align="center" valign="middle"><span class="STYLE1"> <?php echo $page;?> / <?php echo $page_count;?> 页 </span></td> 
<td width="58%" height="28" align="left" valign="middle">
<span class="STYLE1">
<?php
echo "<a href=m.php?page=1>首页</a> ";  
if($page!=1){ 
    echo "<a href=m.php?page=".($page-1).">上一页</a> ";
