Assuming JSON, it is much better (if not even the only *correct* way) to
write

echo json_encode(array(
'image' => '',
'title' => $vid[0],
'file' => "http://www.youtube.com/watch?v={$vid[2]}",
'description' => "{$year} # {$number} - {$vid[1]}"
));

Because you cannot simply insert arbitrary strings in a generated string
literal and hope the outcome will be correct JSON; *at least* you would have
to escape slashes in the inserted strings, and you do not have to do that by
yourself if you use json_encode() in the first place. AISB.
