I have done google api integration code as well as file is upload to a drive. I have issue regarding a uploaded file name is "Untitled". Please review code and guide me what is missing.

going by the documentation at https://developers.google.com/drive/api/v3/reference/files/update , to rename a file, do a PATCH request to https://www.googleapis.com/drive/v3/files/<fileId> with the new name, in your case, i guess that would be
$postResult = curl_exec ( $ch );
$parsed = json_decode ( $postResult, true );
if (! $parsed || $parsed ['code'] !== 200) {
throw new \RuntimeException ( 'google api error: ' . $postResult );
}
$id = $parsed ['id']; // ?? wait, is it id or fileId?
curl_setopt_array ( $ch, array (
CURLOPT_URL => 'https://www.googleapis.com/drive/v3/files/' . urlencode ( $id ),
CURLOPT_POST => 1,
CURLOPT_POSTFIELDS => json_encode ( array (
'name' => basename ( $filename )
) ),
CURLOPT_CUSTOMREQUEST => 'PATCH',
CURLOPT_HTTPHEADER => array (
'Content-Type : application/json',
'Authorization: Bearer ' . getAccessToken ( $credentials )
)
) );
curl_exec($ch);
ps, don't set the Content-Length header manually when using CURLOPT_POSTFIELDS, because curl will do it for you, and if you're using multipart/form-data, the length you set yourself is very likely to be wrong even (doesn't concern your code as you're not using multipart/form-data, but it's a good habit to learn nonetheless, get rid of it.)
