i have problem whit setting cookie

<?php

$cookie_file_path = tempnam('/tmp', 'cookie');

// Login variables
$urls = 'http://mypage.php';
$uname = 'user';
$upass = 'pass';
$unamefield = '*****';
$upassfield = '*****';
$usubmit = 'submit';

// Log into the specified website and return the cURL variable
function login($loginURL, $username, $userFieldName, $password, $passFieldName, $usubmitContent)  {
        // Initialize the page
        $page = curl_init($loginURL);
        // Set POST data
        curl_setopt($page, CURLOPT_POST, 1);
        $postData = $userFieldName . '=' . $username . '&' . $passFieldName . '=' . $password;
        if(!empty($usubmitContent))       $postData = $postData . '&' . $usubmitContent;

        curl_setopt($page, CURLOPT_POSTFIELDS, $postData);
        curl_setopt($page,      CURLOPT_RETURNTRANSFER, true);

        // Set the location of and send the cookies
        curl_setopt($page, CURLOPT_COOKIEJAR, 'cookies.txt');

        // return the cURL variable for later use

}

$page = login($urls, $unamefield, $uname, $upassfield, $upass, $usubmit);
$result = curl_exec($page);

// curl_close($page);

print $result;

$page = curl_init('http://mypage.php');
// Set the location of and send the cookies
curl_setopt($page, CURLOPT_COOKIEFILE, $cookie_file_path);

$result = curl_exec($page);
curl_close($page);

print $result;
?>

i google it to see what is the problem and no luck.

Per your Login variables at the top, it looks like you have your name and password variables incorrectly defined. Shouldn't it be:

// Login variables
$urls = 'http://mypage.php';
$unamefield = 'user';
$upassfield = 'pass';
$uname= '*****';
$upass= '*****';
$usubmit = 'submit';

Your code seems to work fine up to the first print $result;. What is the remaining code there for (i.e. the second curl_init)? Also, use an absolute path to the cookie file. In your login function, do something like this:

$cookie_file = "/tmp/cookies.txt";
curl_setopt($page, CURLOPT_COOKIEJAR, $cookie_file);
