fopen, rewind, and feof errors

[benslayton]

I am getting this error:

Warning: fopen(_users/admin/userpwd.php) [function.fopen]: failed to open stream: No such file or directory in C:\wamp\www\login\common.php on line 14

Warning: rewind(): supplied argument is not a valid stream resource in C:\wamp\www\login\common.php on line 15

Warning: feof(): supplied argument is not a valid stream resource in C:\wamp\www\login\common.php on line 17

Warning: fgets(): supplied argument is not a valid stream resource in C:\wamp\www\login\common.php on line 18

Here is the Code: I think it has something to do with the rewind().... Anyone know a fix?

<?php

session_start();

function registerUser($user,$pass1,$pass2){
    $errorText = '';
    
    // Check passwords
    if ($pass1 != $pass2) $errorText = "Passwords are not identical!";
    elseif (strlen($pass1) < 6) $errorText = "Password is to short!";
    
    // Check user existance    
    $pfile = fopen("_users/" . $user . "/details.php","a+");
    rewind($pfile);

    while (!feof($pfile)) {
        $line = fgets($pfile);
        $tmp = explode(':', $line);
        if ($tmp[0] == $user) {
            $errorText = "Sorry, the selected user name is taken!";
            break;
        }
    }
    
    // If everything is OK -> store user data
    if ($errorText == ''){
        // Secure password string
        //$userpass = md5($pass1);
        $userpass = $pass1;
        
        fwrite($pfile, "\r\n$user:$userpass");
    }
    
    fclose($pfile);
    
    
    return $errorText;
}

function loginUser($user,$pass){
    $errorText = '';
    $validUser = false;
    
    // Check user existance    
    $pfile = fopen("_users/" . $user . "/details.php","r");
    rewind($pfile);

    while (!feof($pfile)) {
        $line = fgets($pfile);
        $tmp = explode(':', $line);
        if ($tmp[0] == $user) {
            // User exists, check password
            if (trim($tmp[1]) == trim($pass)){
                $validUser= true;
                $_SESSION['userName'] = $user;
            }
            break;
        }
    }
    fclose($pfile);

    if ($validUser != true) $errorText = "Invalid username or password!";
    
    if ($validUser == true) $_SESSION['validUser'] = true;
    else $_SESSION['validUser'] = false;
    
    return $errorText;    
}

function logoutUser(){
    unset($_SESSION['validUser']);
    unset($_SESSION['userName']);
}

function checkUser(){
    if ((!isset($_SESSION['validUser'])) || ($_SESSION['validUser'] != true)){
        header('Location: login.php');
    }
}

?>

here is the new code:

<?php

session_start();

function registerUser($user,$pass1,$pass2){
    $errorText = '';
    
    // Check passwords
    if ($pass1 != $pass2) $errorText = "Passwords are not identical!";
    elseif (strlen($pass1) < 6) $errorText = "Password is to short!";
    
        // Secure password string
        //$userpass = md5($pass1);
        $userpass = $pass1;
        
    // Check user existance    
    
  $userDir = "_users/" . $user;
  $filename = $userDir . "/config.php";
  $open = fopen($filename, 'w+');
  $data = "Jane Doe\n";
  fwrite($open, $data);

    if (is_dir($userDir)) {
    echo ("Sorry, but the username is taken.");  
    }
    else
    {
    //fwrite($userDir . $filename, "$user:$userpass"); 
    fwrite($open, $data);
    }
   
      fclose($open);
    
    
    return $errorText;
}

function loginUser($user,$pass){
    $errorText = '';
    $validUser = false;
    
    // Check user existance    
    $userDir = fopen("_users/" . $user . "/details.php","r");
    rewind($userDir);

    while (!feof($userDir)) {
        $line = fgets($userDir);
        $tmp = explode(':', $line);
        if ($tmp[0] == $user) {
            // User exists, check password
            if (trim($tmp[1]) == trim($pass)){
                $validUser= true;
                $_SESSION['userName'] = $user;
            }
            break;
        }
    }
    fclose($userDir);

    if ($validUser != true) $errorText = "Invalid username or password!";
    
    if ($validUser == true) $_SESSION['validUser'] = true;
    else $_SESSION['validUser'] = false;
    
    return $errorText;    
}

function logoutUser(){
    unset($_SESSION['validUser']);
    unset($_SESSION['userName']);
}

function checkUser(){
    if ((!isset($_SESSION['validUser'])) || ($_SESSION['validUser'] != true)){
        header('Location: login.php');
    }
}

?>

I think not all the stream are seekable using rewind/fseek. But i think you can find some method to make a stream seekable in http://www.php.net website.
