#15404 — Syntax error help

I'm getting a parse error (Parse error: syntax error, unexpected '[' in 
/home/sitename/public_html/videos/index.php on line 63) in the below 
YouTube video search script.

I believe line 63 to be...
$video = youtubeGetVideo($id)['snippet'];

This error showed up after I moved this script to a different server. I 
think it might have something to do with the new server running a 
version of PHP earlier than 5.4. Either that or there's a bracket or 
semicolon that isn't closed, however it did work OK on the other server.

If anyone has any idea what could be causing this and a fix I'd really 
appreciate it.

Indeed, this syntax is available only as of PHP 5.4.0: "Function array
dereferencing has been added, e.g. foo()[0]."[1]  For older versions
(which might better be avoided, because they are no longer supported),
you can get around the issue by assigning the function return value to
an auxiliary variable, and to access the desired element on that:

  $aux = youtubeGetVideo($id);
  $video = $aux['snippet'];

That did it! Thank you very much Chris.
