This article illustrates how PHP reads a txt text file and displays it in pages. Share to everyone for your reference. The implementation methods are as follows:
<?php
Session_Start ();
if (empty ($page)) {$page = 1;}
if (Isset ($_get[' page ') ==true) {$page =$_get[' page '];}
?>
<meta http-equiv= "Content-type" content= "text/html; Charset=utf-8 "/>
<title>read result</title>
<style type= "Text/css" >
<!--
. STYLE1 {font-size:12px}
. STYLE2 {font-size:18px}
-->
</style>
<body>
<table width= "100%" bgcolor= "#CCCCCC" >
<tr>
<TD >
<?php
if ($page) {
$counter =file_get_contents ("Example.txt"); Read TXT file contents to $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;
}
------------Intercept Chinese string---------
$c =msubstr ($counter, 0, ($page-1) *5000);
$c 1=msubstr ($counter, 0, $page *5000);
Echo substr ($c 1,strlen ($c), strlen ($c 1)-strlen ($c));
