- <?php //----------------you should save this file as m.php----------------
- session_start();
- if (emptyempty($page)) {$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">
