by using a simple example of FQL query we get an array of details of photos of particular album

require '../src/facebook.php';

 $facebook = new Facebook(array(
  'appId'  => '...',
  'secret' => '...'));

function get_photos_by_album_id($album_id){

if($album_id)
        $fql            =   'SELECT pid,src_big,owner,link,position,created,caption,src FROM photo WHERE aid="'.$album_id.'"';
           
                $param  =   array(
                'method'    => 'fql.query',
                'query'     => $fql,
                'callback'  => ''
            );
            $fqlResult   =   $facebook->api($param);
    return $fqlResult;

}

Create photo albums and upload photos using the Facebook

By using Facebook graph API allow us to access public information like user's first name, last name and profile picture are publicly available. To get additional access like upload photos,create albums,you must first get their permission.

The code example assumes that you have already generated an authenticated session while generating the loginUrl we need to specify scope for the permission (photo_upload, user_photos)

 require '../src/facebook.php';$facebook = new Facebook(array(
  'appId'  => '...',
  'secret' => '...'));$loginUrl=$facebook->getLoginUrl( array(
                'scope'         = 'email,
                                   publish_stream,
                                   user_birthday,
                                   read_stream,
                                   photo_upload,
                                   user_photos,
                                   user_photo_video_tags,
                                 );
echo "<script type="text/javascript">
top.location.href = '$loginUrl';
// ]]></script>";?>
 
 permission popup once we get the permission from user we can able to upload the photos to there albums

 <?php
$facebook->setFileUploadSupport(true);

//Create an album
$album_details = array(
        'message'=> 'Album desc',
        'name'=> 'Album name'
);
$create_album = $facebook->api('/me/albums', 'post', $album_details);

//Get album ID of the album you've just created
$album_uid = $create_album['id'];
  //Upload a photo to album of ID...$photo_details = array(
    'message'=> 'Photo message');$file='app.jpg'; //Example image file$photo_details['image'] = '@' . realpath($file);

HTTP POST Using PHP CURL

Here's how you execute a POST using the PHP CURL library.

//define post values 
$message="test message ";//define post url
 $url="http://localhost/WebServices/";//encode the message
 $message = urlencode($message);//initialize the curl
 $ch = curl_init();

 if (!$ch){
die("Couldn't initialize a cURL handle");
}//setting options
 $ret = curl_setopt($ch, CURLOPT_URL,$url);
  curl_setopt ($ch, CURLOPT_POST, 1);
 curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);       
 curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);//setup post fields
 curl_setopt ($ch, CURLOPT_POSTFIELDS,"Message=$message");
 $ret = curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//If you are behind proxy then please uncomment below line and provide your proxy ip with port.
// $ret = curl_setopt($ch, CURLOPT_PROXY, "PROXY IP ADDRESS:PORT");

//execute and geting response
 $curlresponse = curl_exec($ch);

if(curl_errno($ch))
    echo 'curl error : '. curl_error($ch);

 if (empty($ret)) {
    // some kind of an error happened
    die(curl_error($ch));
    curl_close($ch); // close cURL handler
 } else {
    $info = curl_getinfo($ch);
    curl_close($ch); // close cURL handler
    //echo "<br>";
    echo $curlresponse;    //echo "post message Sent Succesfully" ;
    }
 }
