The example in this article describes how PHP reads a txt text file and displays it in pages. Share it with everyone for your reference. The specific implementation method is as follows:

Copy code The code is as follows: Session_start();
If (empty($page)) {$page=1;}
If (isset($_GET['page'])==TRUE) {$page=$_GET['page']; }
?>

if($page){
$counter=file_get_contents("example.txt"); //Read the contents of the txt file 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) {
$tmpstr.='
';
}
If(ord(substr($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);
$c1=msubstr($counter,0,$page*5000);
echo substr($c1,strlen($c),strlen($c1)-strlen($c));
}?>
