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($_GET[&#39;page&#39;])==TRUE) {$page=$_GET[&#39;page&#39;]; }
?> 
<html> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> 
<title>Read Result</title> 
<style type="text/css"> 
<!-- 
.STYLE1 {font-size: 12px} 
.STYLE2 {font-size: 18px} 
--> 
</style> 
</head> 
<body> 
<table width="100%" bgcolor="#CCCCCC"> 
<tr> 
<td > 
<?php 
if($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) { 
    $tmpstr.=&#39;<br />&#39;;
  }
  if(ord(substr($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> 
</table> 
</body> 
</html>
