Explode not working - need URL path

[Johnny_NW]

I am really confused here....

 

I'll insert URL for an embeded video, and it does embed the video onto the website.

 

And it also grabs the associated video thumbnail for that video from hosting server, IF and ONLY IF I put an absolute URL for the video thumbnail.

This isn't cool, because I don't want all my embed videos to have the same video thumbnail.

 

So the code works like this, but this gives the same video thumbnail for all videos:

$thumbnail = "http://cdn1.image.website.webcdn.com/201111/09/664006/original/8.jpg";

What I am tryign to do is get to /664006/ and insert my variable $url_id, which this works too, BUT still only the same video thumbnail /201111/09 :

$thumbnail = 'http://cdn1.image.website.webcdn.com/201111/09/' . $url_id . '/original/8.jpg';

So I know I need to get through /201111/09 to get to $url_id BUT THIS IS NOT WORKING

 

WHY is this not working? PLEASE any help would be sincerely appreciated:

$thumbnail = 'cdn1.image.website.webcdn.com/201111/09/664006/original/8.jpg';
$arr = explode('/', $thumbnail);
$url_id = $arr[3];
$thumbnail = 'cdn1.image.website.webcdn.com/'. $arr[1] . '/' . $arr[2] . '/' . $url_id . '/original/8.jpg';

Thanks for your help, in advance!

The "cdn1.image.website.webcdn.com" is NOT a web root directory, it's a domain name of the web server.

 

Try,

$thumbnail = $_SERVER['DOCUMENT_ROOT'].$arr[1] . '/' . $arr[2] . '/' . $url_id . '/original/8.jpg';

Unfortunately, not working

 

I tried all of these:

$thumbnail = $_SERVER['DOCUMENT_ROOT'] . $arr[1] . '/' . $arr[2] . '/' . $url_id. '/original/8.jpg';
$thumbnail = $_SERVER['SERVER_NAME'] . $arr[1] . '/' . $arr[2] . '/' . $url_id. '/original/8.jpg';
$thumbnail = $_SERVER['HTTP_HOST'] . $arr[1] . '/' . $arr[2] . '/' . $url_id. '/original/8.jpg';

And I even tried:

$thumbnail = $_SERVER['DOCUMENT_ROOT'] . '/'. $arr[1] . '/' . $arr[2] . '/' . $url_id. '/original/8.jpg';

Any other suggestions? I am totally desperate for an answer, to be honest

What result you get if you try to echo the $thumbnail variable.

$thumbnail = $_SERVER['DOCUMENT_ROOT'] . '/'. $arr[1] . '/' . $arr[2] . '/' . $url_id. '/original/8.jpg';

echo $thumbnail;
