Display total online users in web page

Here, how you can display total number of online user in your webpage you want. Just include file name, which I have given file name as online-user.php here. You need to include this file on any php page you want to display total users online.

I have developed this php script to implement on my own webpage.
See this, I have implement this on https://www.ashesh.com.np/nepali-date-converter.php

Example for how to include online-user.php in web page.

online-user.php

$file1 = 'online-user-ashesh/ip.txt';
$lines = file($file1);
$line2 = "";

foreach ($lines as $line_num => $line)
 {
  //echo $line."
";
  $fp = strpos($line,'****');
  $nam = substr($line,0,$fp);
  $sp = strpos($line,'++++');
  $val = substr($line,$fp+4,$sp-($fp+4));
  $diff = $sd-$val;
  if($diff < 900 && $nam != $rip)
   {
    $count = $count+1;
    $line2 = $line2.$line;
    //echo $line2;
   }
 }

$my = $rip."****".$sd."++++\n";
$open1 = fopen($file1, 'w');
fwrite($open1,"$line2");
fwrite($open1,"$my");
fclose($open1);

echo "

And you need to create empty text file called ip.txt as described in online-user.php code.
