本文实例讲述了PHP读取txt文本文件并分页显示的方法。分享给大家供大家参考。具体实现方法如下：

代码如下:<?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">

</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>
<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=".($page-1).">上一页</a> ";
}
if($page<$page_count){
    echo "<a href=m.php?page=".($page+1).">下一页</a> ";
}
echo "<a href=m.php?page=".$page_count.">尾页</a>";
?>
</span> </td>
</tr>
