create a shortcut to a file in google drive api php client v2

I believe your goal and situation as follows.

• You want to create new shortcut using googleapis for php.
• You have already been able to use Drive API.

In this case, I would like to propose to use setShortcutDetails() in your script. When your script is modified, it becomes as follows.

Modified script:

$file = new \Google_Service_Drive_DriveFile();
$file->setName('Shortcut Name');
$file->setParents([$parent_id]);
$file->setMimeType('application/vnd.google-apps.shortcut');

$shortcutDetails = new \Google_Service_Drive_DriveFileShortcutDetails();
$shortcutDetails->setTargetId($file_id);
$file->setShortcutDetails($shortcutDetails);

$createdFile = $service->files->create($file);

• Please set $parent_id and $file_id.
