There are multiple errors with your code. You can simple use file_put_contents to add content to cache file.
Try the following example
$id = 'DU6IdS2gVog';
$cache_path = 'cache/';
$filename = $cache_path.md5($id);
if( file_exists($filename) && ( time() - 84600 < filemtime($filename) ) )
{
$data = json_decode(file_get_contents($filename), true);
}
else
{
$data = data_get_curl('https://www.googleapis.com/youtube/v3/videos?key={API_KEY}&fields=items(snippet(title%2Cdescription%2Ctags))&part=snippet&id='.$id);
file_put_contents($filename, $data);
$data = json_decode($data, true);
}
