A Simple PHP Visitor Counter
Design a simple PHP counter without using MySQL database, only using an external file 'visitorcounter.txt'. PHP functions used here: file_exists, fopen, fwrite,fgetc,fclose.
visitorcounter.php
<?php
//A simple PHP counter
//Using external file visitorcounter.txt
//to store counter instead using MySQl database
function visitorcounter()
{
$file='visitorcounter.txt';
if(!file_exists($file)){
$counter = 0;
$cf=fopen($file,"w");
fwrite($cf,$counter);
fclose($cf);
}else{
$cf=fopen($file,"rw");
$counter=fgetc($cf);
fclose($cf);}
$counter++;
$cf=fopen($file,"w");
fwrite($cf,$counter);
fclose($cf);
return $counter;
}
?>
index.php, call visitorcounter.php
<?php
require("visitorcounter.php");
?>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Visitor Counter</title>
<meta name="author" content="Jiansen" />
