Using Dailymotion Api in BB Code Template

[XiTCLUB]

Hi,
I wanted to use HTML5 schema in my BB code templates and wanted to fetch video data via dailymotion API and for that i have to create and echo variables inside template

The code i am using is

PHP Code:

<?php
$id={vb:raw code};
$thumbnail_medium_url='https://api.dailymotion.com/video/'.$id.'?fields=thumbnail_720_url';
$json_thumbnail = file_get_contents($thumbnail_720_url);
$get_thumbnail = json_decode($json_thumbnail, TRUE);
$thumb=$get_thumbnail['thumbnail_720_url'];
?>

and i am echoing it like this

PHP Code:

<?php echo $thumb ?>

but this is not working like it should and just printing whole statement as it is
