»»» A simple counter using php

This quick example shows you how to display the browser information of a visitor to your website using php. It's very basic. You should 1st create a file to store the hits in, in this example we used a file called 'mycount.dat' & started the count at 100. You can start it at 1 or 1 million, up to you.

Here is the script for this example

<?php
//A simple counter using php
//open the counter file in read only mode
$counterfile = "mycount.dat";
if(!($fp = fopen($counterfile,"r"))) die ("cannot open counter file");
//Check the value stored in the file
$count = (int) fread($fp, 20);
//close the file
fclose($fp);
//increment the count
$count++;
//display the count
echo "Welcome visitor no : $count";
//open the file again in write mode (w) and store
// the new count
$fp = fopen($counterfile, "w");
fwrite($fp , $count);
//close the file
fclose($fp);
?>

And here is the output , refresh your browser to increment the count.

You can drop this snippet anywhere you like, but the page you put it into must be able to parse PHP code. So it should end in *.php
