Step 2

Alright, now that we've got our files set up, lets start codin'. Open up counter.php (or whatever you named it) and type the PHP tags.

<?php

?>


Step 3

Now, we open up the flat file (hits.txt) and tell PHP to read the number inside and set it as a variable (we've already put "0" into hits.txt)

<?php
 $hits = file_get_contents("hits.txt");

?>


The function file_get_contents reads all the text in the file that is quoted in the first argument (the first argument being hits.txt in this case) and puts it into a string. A string is simply data. It could be text, numbers, anything. In this case, it is only one thing -- a number.

When we put "$hits =", this means we are defining a variable. In this case, we are saying that the variable $hits (all variables must have a dollar sign before it) is equal to everything inside hits.txt (which in this case, is only "0").
