Adding variable to this..

[V]

I'm using CURL to retrieve thumbnails from youtube videos and save into a image folder.

 

I'm trying to replace the url in this code

 

 

curl_setopt($ch, CURLOPT_URL, 'http://img.youtube.com/vi/QYHzyLrtvBY/0.jpg');

 

with this

 

http://img.youtube.com/vi/echo $out['v'];

 

echo $out['v] echoes that long youtube code at the end. I tried more variations but I keep getting errors, is it possible to use a variable with CURL?  :-\

 

 

[trq]

curl_setopt($ch, CURLOPT_URL, 'http://img.youtube.com/vi/' . $out['v']);

Wow thanks! I seem to forgot the basics..
