/*
  
  
| A simple counter
  
  
*/
  
  
Function get_hitcount ($ counter_file)
  
  
{
  
  
/* Returns the counter to zero.
  
  
In this case, if the counter is not used, the initial value is 1.

*/
  
  
$Count=0;
  
  
// If the stored counter file already exists, read the content
  
  
If (file_exists ($ counter_file ))
  
  
{
  
  
$Fp=Fopen($ Counter_file, "r ");

$Count=0+ Fgets ($ fp, 20 );

Fclose ($ fp );
  
  
// File operation completed

Return ($ count );
