Answer 1

I believe your goal and current situation as follows.
You want to use "Files: emptyTrash" in Drive API v3 using curl of php.
Your access token of $token can be used for using this API.
In order to achieve your goal, how about the following modification?
From:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://www.googleapis.com/drive/v3/files/trash?key='.$token.'");
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-type: application/json',
'Authorization: Bearer ' . $token
));
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "DELETE");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
curl_close($ch);
To:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://www.googleapis.com/drive/v3/files/trash");
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Authorization: Bearer ' . $token));
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "DELETE");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
curl_close($ch);
Note:
At "Files: emptyTrash", no values are returned.
If $token in your script is the API key which is not the access token, please retrieve the access token and use it. Please be careful this.
