Simple Text Counter

A common feature on most websites is a counter to show how many visitors have been to your site. This is our first example to show how to achieve this .
This example is very basic and far from ideal if you want an accurate count of your visitors because if you press refresh your counter will always increment by 1. This example does show some useful techniques such as opening and closing files.

Lets go through the process one step at a time . Firstly you have to create a simple text file and enter the number you wish the counter to start at , note this does not have to be 1 it can be any number you wish.
The next task will be to upload this to your server , if you have a Unix server this is where you have to watch because you have to set the permissions for your text file so the script can read and write to the file .
To change this you CHMOD your text file to 755. Refer to the help file or documentation of your FTP program to see how to achieve this.

Now for the script , call this something like counter.php

PHP Code:


			
<?php 

//this is our text file if you create a different named file change the script below to reflect this 

$counter_file = ("counter.txt"); 

//now we open the file 

$visits = file($counter_file); 

//this increments the counter value by 1 

$visits[0]++; 

//now we will open the counter file for writing "w" 

$fp = fopen($counter_file , "w"); 

//put the new count value into the counter file 

fputs($fp , "$visits[0]"); 

//close the file 

fclose($fp); 

//display the count 

echo "There have been $visits[0] visitors so far"; 

?>

Now add the following to your page where you wish the counter to appear

PHP Code:


			
<?php include("counter.php"); ?>

And that's it. You now have a working counter ready to be used!
