PHP will read the text and display it in pages
This article mainly introduces the text that PHP will read and displays it in pages. Interested friends can refer to it. I hope it will be helpful to everyone.
The code is as follows:
<?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>
<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>
