file_get_contents php method call to facebook loading very slow

when try to get content from an URL, php provide a method "file_get_contents", sometime when you use this method it might takes too long to load.

the following code is used to get the user basic profile from facebook,

$graph_url = "https://graph.facebook.com/me?" . $access_token;
$fbdetail = file_get_contents($graph_url);
$user = json_decode($fbdetail);

for me, file_get_contents takes 5-10 second to load the above code, some say its an DNS issues, below is another function to replace file_get_contenst, it takes less than 3 second for me to load.

just include the below code and replace "file_get_contents" with "get_url"

function get_url($url)
 {
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_HEADER, 0);
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_TIMEOUT, 5);
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
  $tmp = curl_exec($ch);
  curl_close($ch);
  return $tmp;
 }

Multi Friend Selector Popup using FB.UI for Facebook Tab and App

Facebook tab only takes 520px, or if you develop facebook apps with width less than 580, you will get the invitation preview dialog cuts off when you are using the multi friend selector.

I can't find any way to resize the invitation preview dialog, so i made a popup multi friend selector.

First of all, remember to do FB.init, get the code here, I'm using the "Asynchronous Loading"

In invite.php(or where you want to put the MFS in), put the below code

Now the button to call up the multi friend selector:

Here's some important notes:
1) display: 'popup' - without this, the FB.UI won't works in facebook tab
2) display: 'dialog' - does not works in facebook tab, use this in facebook app, it looks better
3) Once invitation is send, it will goes to share.php, share.php will be the page you get IDS from your mfs, you can echo a javascript windows close at share.php at the end of your code
4) back to invite.php, you'll see i put both self.location.href = 'thank.php'; in the response statement, whether there is a response or not, i direct the facebook tab to thank.php

Hope this help.
