i'm new at this so please forgive me for asking something dumb

PHP Code:

    if(file_exists($filename))
    {
        // set the file to read
        $newfile = fopen($filename, "r");
        while(!feof($newfile))
        {
            if(stripos(file_get_contents($filename), $email) !== false)
            {
                $content = "Our records show that this email address is already registered";
                fclose($newfile);
                die("$front\n$content\n$back");
            }
        }
        fclose($newfile);
        $addemail = fopen($filename, "a");
        // let's add the email address
        fputs($addemail, "$email\n");
        fclose($addemail);
    } 


had this working fine earlier, now all of a sudden i'm trying to use it and it's stopped have i done something wrong somewhere?

Warning: fopen(../../file.txt): failed to open stream

Warning: fputs(): supplied argument is not a valid stream resource in 

Warning: fclose(): supplied argument is not a valid stream resource in 

Warning: chmod(): No such file or directory in

it wrote to the file fine at first so what's changed?

is it possible the host disabled the features?

after all the code still works fine on my localhost.
