Display Flickr images using the API with PHP and cURL

Working on a small project whereby I need to tap into my clients Flickr account and display the images on his site. He wants them to loop through with jQuery but I will not showcase that code but will show the initial code to load in 5 images from Flickr and hold them in an array for later use.

First is the class code (flickr.cls.php): 

class Flickr
{
    public function __construct($username = null, $user_id = null, $api_key = null)
    {
        $this->Username = $username;
        $this->Api_key  = $api_key;
        $this->User_id  = $user_id;
        $this->Response = array();
        $this->Timeout  = 5;
    }
    public function getImages($count)
    {
        $url = 'http://api.flickr.com/services/rest/?api_key=' . urlencode($this->Api_key) . '&method=flickr.photos.search&user_id='.$this->User_id.'&per_page=' . urlencode($count);
        //echo $url;
        return $this->fetch($url);
    }
    
    public function fetch($url,$post = false)
    {
        $ch = curl_init($url);
        curl_setopt($ch, CURLOPT_NOBODY, 0);
        curl_setopt($ch, CURLOPT_HEADER, 0);
        curl_setopt($ch, CURLOPT_USERAGENT, 'Flickr PHP Class by PHPology');
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_TIMEOUT, $this->Timeout);
        $output = curl_exec($ch);
        $this->Response = curl_getinfo($ch);
        curl_close($ch);
        if((int)$this->Response['http_code'] == 200) {
            return new SimpleXMLElement($output);
        }
        else {
            return false;
        }
    }
} 

Next is the code to pull in the relevant images based on the Flickr user_id and API key:

require("services/models/flickr.cls.php");

$flickr = new Flickr('USER_ID', 'USER_ID', 'API-KEY');
$images = $flickr->getImages(5);

$flickr_array = array();
$i = 0;
if(count($images->photos->photo) > 0)
{
	foreach($images->photos->photo as $photo) 
	{
		$flickr_array[$i]['image_href'] = "http://flickr.com/photos/".$flickr->Username."/".$photo->attributes()->id."";
		$flickr_array[$i]['image_path'] = "http://farm". $photo->attributes()->farm.".static.flickr.com/".$photo->attributes()->server."/" .$photo->attributes()->id."_".$photo->attributes()->secret."_n.jpg";

		$i++;
	}
}
print_r($flickr_array);

You can now loop through $flickr_array where you need.

You can change the image size that you require also (currently I am pulling in "_n") but you can use this as a good resource to display the size you need: http://www.flickr.com/services/api/flickr.photos.getSizes.html

In an ideal world, you would want to cache this some how as retrieving data from Flickr on every page call would be slightly slow.
