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'];
