Simple Hit counter

A hit counter will let us know how many times a page is accessed. Incase one visitors loads the page several times, the hit counter willincrease several times (but this is likely to happen only a few times).

The code for the hit counter bellow will save the number of hits in afile named counter.txt(the name of this file may be changed). Each time the page is loaded,the file will be read, the number will be increased by one and the newnumber will be saved to the same file.

Counter.php

<?php


//The file where number of hits will be saved; name may be changed;p.e. "/counter_files/counter1.txt"
$counterfile = "counter.txt";


// Opening the file; number of hit is stored in variable $hits
$fp = fopen($counterfile,"r");
$hits= fgets($fp,100);
fclose($fp);


//increading number of hits
$hits++;

//saving number of hits
$fp = fopen($counterfile,"w");
fputs($fp, $hits);
fclose($fp);

//printing  hits; you may remove next line (and keep the counteronly for your records)
print $hits;

?>

To use this code, copy itto your page in the exact position where you want to show number ofhits. If your page is a ".html" page, change the extension to ".php".Them, visit your page. In the first visit, you will get a couple oferrors (the file where number of hits are recorded does not exists, sosome errors will be shown in the page). Reload the page and you willsee no errors. The hit counter will be working.

In case you want to use different hit counters for different pages,chage name of $counterfile for each page (p.e.: counter1.txt,counter2.txt, etc).
