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)
        $url = '' . urlencode($this->Api_key) . '&'.$this->User_id.'&per_page=' . urlencode($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);
        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:



$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'] = "".$flickr->Username."/".$photo->attributes()->id."";
		$flickr_array[$i]['image_path'] = "http://farm". $photo->attributes()->farm."".$photo->attributes()->server."/" .$photo->attributes()->id."_".$photo->attributes()->secret."_n.jpg";



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:

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.
