How to display the Facebook profile photo in my php project - php

Question

In my project I am signing in with a Facebook account, but the profile page displays the image from gravatar.com. I want to display the profile image from www.facebook.com of registered users.
In my local system I have the following code to display profile photo from www.gravatar.com
public function gravatar($email, $s = 80, $d = 'mm', $r = 'g', $img = FALSE, $atts = array())
{
$url = 'https://secure.gravatar.com/avatar/'
. md5(strtolower(trim( $email)))
. "?s=$s&d=$d&r=$r";
if ($img)
{
$url = '<img src="' . $url . '"';
foreach ($atts as $key => $val)
{
$url .= ' ' . $key . '="' . $val . '"';
}
$url .= ' />';
}
return $url;
}
How can I display the Facebook profile photo instead of gravatar.com profile photo?

Answer 1

You can link to https://graph.facebook.com/usernameOrId/picture.

Answer 2

Something like this:
function facebookAvatar($uid, $img = FALSE, $atts = array())
{
$url = 'https://graph.facebook.com/'.trim($uid).'/picture';
if ($img)
{
$url = '<img src="' . $url . '"';
foreach ($atts as $key => $val)
{
$url .= ' ' . $key . '="' . $val . '"';
}
$url .= ' />';
}
return $url;
}
and to get the Image use:
<?php echo facebookAvatar('UsernameOrUserID', TRUE, array('width'=>'80px', 'height'=>'80px')); ?>
UsernameOrUserID you've to change to the UserID:
1234321
if the url is:
http://facebook.com/profile.php?id=1234321
or to the username:
my.name
if the facebook url is http://facebook.com/my.name

Answer 3

If you are using PHP SDK you can get the userId of the current logged in USer and display the user Image.
You can do like this:
require_once 'path/to/facebookSDK.php';
$facebook = new Facebook(array(
'appId' => 'YOUR_APP_ID',
'secret' => 'YOUR_APP_SECRET',
));
// Get User ID
$user = $facebook->getUser();
//this will ouptput your current logged in user facebook image
echo getFacebookPhotoAvatar ($user);
function getFacebookPhotoAvatar ($user) {
if($user) {
$photoUrl = "https://graph.facebook.com/".$user."/picture";
$facebookPhoto = '<img src="'.$photoUrl.'" alt="FacebookUserImage"/>';
} else {
$facebookPhoto = '';
}
return $facebookPhoto ;
}
Hope this helps :)
