Problema Contatore Accessi

[danlupo]

Salve ho un problema con questo codice

<?php
    session_start();
 $html_result="";
$count_file= $_SERVER['DOCUMENT_ROOT'] . "/contaccessi.txt";
$NUM_DIR_URL="/../images/website/DIGITS/";
$NB_DIGITS=8;

if (file_exists($count_file))
    {
        $fp = fopen("$count_file","r+");
        flock($fp,1);
        $count=fgets($fp,4094);
        fclose($fp);
        if(!isset($_SESSION["visita"]))
            {
            $fp = fopen($count_file, "w");
            $c= $count;
            $c++;
            fwrite($fp, $c); 
            fclose($fp);
            $count = $c;
            $_SESSION["visita"] = 1;
            }
    }
else
    {
        echo "Non Trovato il File '\$count_file' 
";
    }
$action="contatore";
chop($count);
$nb_digits=max(strlen($count),$NB_DIGITS);
$count=substr("0000000000".$count,-$nb_digits);
$digits=preg_split("//",$count);
for($i=0;$i<=$nb_digits;$i++)
    {
        if ($digits[$i]!="")
            {
                $html_result.="<IMG SRC=\"$NUM_DIR_URL$digits[$i].gif\">";
            }
    }
?>

Semplicemente non aggiorna mai il contatore visite..

Grazie Daniele
