Nu hvor du har oprettet filen, lad være med at teste den. Vi er nemligt ikke færdige endnu.

Opret en undermappe med årstallet, f.eks. 2009, i samme mappe som test_counter.php så test_counter.php ligger et niveau højere oppe. (Der skal hvert år oprettes en mappe med årstallet.)


Opret tolv filer i mappen 2009. Disse skal hedde 1 .txt , 2.txt etc. (sidste mappe skal hedde 12.txt).


Lad os nu gå igang med add_counter.php
#############################################
######### add_counter.php - start ###########
#####Taget fra http://www.freescripts.com/text-counter.php#####
<?php

//Give basic values
$year = date("Y"); //Write the current year in variable $year
$month = date("n");

########CHANGE THIS VALUE##############
$root = ""; //Write where the file is saved eksample: /home/mydomain/www/counter/ DON'T WRITE THE FILE NAME


$counter_file = ($root . "" .$year."/".$month.".txt"); //file where count is stored
$visits = file($counter_file); //puts the count in a variable
//Don't count the vistets of the admin
$visits[0]++; //add 1 to the counter file
$fp = fopen($counter_file , "w"); //open the file for write
fputs($fp , "$visits[0]"); //write the new value to the file

fclose($fp);

?>

Her bliver der tællet per loadinger. Ønsker du en mere fair counter, kan bruge http://www.phpuniverset.dk/show_artikels.phtml?ArtikelID=21
og stykke noget sammen.


Før scriptet kan bruges, skal der tilføjes en værdi til en af txt filerne.
