Free Page counter PHP script

This free page counter php script uses the fopen(), fread(), fwrite(), and fclose() functions to read and update a text file that stores the current value of the counter. The text file “counter.txt” must be created and initially set to zero before this script can be used.

<?php
  // Open the text file
  $file = fopen("counter.txt", "r");
  // Read the current value of the counter
  $count = fread($file, filesize("counter.txt"));
  // Close the file
  fclose($file);
  // Increment the counter
  $count = $count + 1;
  // Open the file for writing
  $file = fopen("counter.txt", "w");
  // Write the new value to the file
  fwrite($file, $count);
  // Close the file
  fclose($file);
?>
