i searched for 2 days about my problem find a lot of solution but none worked for me.
I want to make a facebook application that i will access from cronjob once for 20 minutes.
This app shoult post to my page a photo with description in a album. The problem is the token access that expires … so the code …

//connect to api
$facebook = new Facebook(array(
          'appId'  => APP_ID,
          'secret' => APP_SECRET
        ));

//get the page token
$page_id = 222506244512259;
$page_info = $facebook->api("/$page_id?fields=access_token");

$page_info['access_token']; //so if i use this token is ok but it expires in 2 hours

//now we try to use something else to extend the time

$token_url="https://graph.facebook.com/oauth/access_token?client_id=".APP_ID."&client_secret=".APP_SECRET."&grant_type=fb_exchange_token&fb_exchange_token=".$facebook->getAccessToken();

//so if i use this formula i will receive a token that never expires, is ok but if I try to use the acces token for posting it doesn work is not valid

$response = file_get_contents($token_url);
$params = null;
parse_str($response, $params);
$page_info['access_token'] = $params['access_token'];


//and this is the rest code for posting

$image['file'] = 'images/rezultate/'.$link;
$args = array( 'access_token' => $page_info['access_token'], 'message' => ':-) <3', 'no_story' => 0);
$args['image'] = '@' . $image['file'];
$target_url = "https://graph.facebook.com/356048711158011/photos";

$ch = curl_init(); 
curl_setopt ($ch,CURLOPT_URL,$target_url); 
curl_setopt ($ch, CURLOPT_POST, 1); 
curl_setopt ($ch, CURLOPT_RETURNTRANSFER,1); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $args);
curl_exec($ch); 
curl_close ($ch);

I updated the code but still not working, maybe you some something wrong…

//start facebook
$facebook = new Facebook(array(

//get page id and 2 hour page token
$page_id = 222506244512259;
$page_info = $facebook->api("/$page_id?fields=access_token");
//access token 2 hours
$page_info['access_token'];

//here i get my account but for nothing
$acc = $facebook->api("/100001036884257/accounts");
//echo var_export($acc, true);


//here i get the long token it returns a code value but when i used down don`t work
$longtoken = 'https://graph.facebook.com/oauth/access_token?client_id='.APP_ID.'&client_secret='.APP_SECRET.'&grant_type=fb_exchange_token&fb_exchange_token='.$facebook->getAccessToken();     
$response = file_get_contents($longtoken);
$params = null;
parse_str($response, $params);
$longtoken = $params['access_token'];

echo"Acces Token short: ".$page_info['access_token'];
echo"<br />Acces Token long: ".$longtoken;

//here i get my folder picture and pictures
$a = file_get_contents('http://www.ingersidemon.ro/proiecte/pitzi-world.ro/.facebook/postareautomata/images/rezultate/');
$dom = new DOMDocument;
$dom->loadHTML($a);
$nodes = $dom->getElementsByTagName('a');
$nrpoze = $dom->getElementsByTagName('a')->length - 1;
$picid = get_last_picture();
$link = $nodes->item($picid['id'] + 1)->getAttribute('href');
//echo "Link poza: ".$link;



if($picid['id'] + 1 <= $nrpoze) {
    $data = array(
        'link' => $link,
        'desc' => ':-) <3'
    );
    insert_picture($data);
//and here is the bog problem if i use short acces token it works for 2 hours but the long never work
    $params = array('access_token' => '$longtoken', 'message' => ':-) <3');
    $params['source'] = '@' . realpath('images/rezultate/'.$link);
    $facebook->setFileUploadSupport(true);
    $post_id = $facebook->api('/'.$page_id.'/photos','post',$params);

}

Update 3: The app is working good but only if i acces it, not from cronjob, and the acces token is for 2 months, in cronjob gives
