Sarà un errore che avrai di frequente, aimé.
Comunque l'idea era questa:
Codice PHP:
<?php 
ob_start(); 
//prima di qualsiasi cosa e senza spazi prima
function NumeroVisite() 
{ 
     
    $file = "./public/conta.txt"; 
    if (!file_exists($file)) { 
        $file = fopen($file, 'w'); 
        fwrite($file, "0"); 
        fclose($file); 
    } 
    return file_get_contents("./public/conta.txt"); 
} 


function Conta() 
{ 
    if(!isset($_COOKIE['visite'])) 
    { 
        $visite = NumeroVisite(); 
        $visite++; 
        $fr = fopen("./public/conta.txt", "w+"); 
        fwrite($fr, $visite); 
        fclose($fr); 
        setcookie("visite", "settato", time() + 7200); 
    } 
} 
//alla fine di tutto.
ob_end_flush(); 
?>
e poi:
