Restservice with curl simpleget not working - php

Question

I'm trying to use my webservice by curl:
public function getImages($time) {
$url = $this->rest_url['employees'] . "?action=getAllNewPhotos&accessKey=" . $this->rest_key['employees'] . "&lastcheck=" . $time;
$data = $this->CI->curl->simple_get($url);
if ($data) {
return json_decode($data);
} else {
return null;
}
}
But it keeps giving me the following error:
Fatal error: Call to a member function simple_get() on a non-object
Why is that?
Also if I add curl in my autoload it says:
Unable to load the requested class: curl
However if I run my code by following code, there is no problem:
$url = $this->rest_url['employees'] . "?action=getAllNewPhotos&accessKey=" . $this->rest_key['employees'] . "&lastcheck=" . $time;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($ch);
if ($data) {
return json_decode($data);
} else {
return null;
}
I'm just curious why my first approach is not working!
If you need more clarification, please let me knwo!
Thanks

You seem to be mixing a few things.
If you want to load this as a Codeigniter library, you need to first create it as one. Steps are found in the User Guide. This will go in your libraries directory.
simple_get() should then be a function on your class library called "curl". However, I would probably use a different name to avoid naming clashes
