I'll be happy to help with any issues you're having with the Dropbox API, but I'll need some more information. Please reply with:

the name and version number of the platform and SDK/library you are using, if any
the steps to reproduce the issue, including relevant code snippet(s), but don't include any access token(s)
the full text of any error or unexpected output

$fileURL = 'http://localhost/wordpress/wp-content/uploads/2021/05/my-file.txt';

$tempFilePath = basename($fileURL);

try{
$path = $tempFilePath;
$fp = fopen($path, 'rb');
$size = filesize($path);

$cheaders = array('Authorization: Bearer <ACCESS_TOKEN>',
'Content-Type: application/octet-stream',
'Dropbox-API-Arg: {"path":"/'.$path.'", "mode":"add"}');

$ch = curl_init('https://content.dropboxapi.com/2/files/upload');
curl_setopt($ch, CURLOPT_HTTPHEADER, $cheaders);
curl_setopt($ch, CURLOPT_PUT, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($ch, CURLOPT_INFILE, $fp);
curl_setopt($ch, CURLOPT_INFILESIZE, $size);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$resp = curl_exec($ch);
curl_close($ch);
fclose($fp);

$jsonData= $resp; // put here your json object
$arrayData = json_decode($jsonData, true);
if($arrayData['size'] != 0 ){

print_r($arrayData);
// Removed file from this server atfer moved in dropbox Storage.
wp_delete_attachment($dt['upload_file_id'] );

$response = array('status' => 'success');
$response['success'] = true;
}

I am getting this output:-

array printed:

)

Response which I am getting :

I just gave this a try myself, plugging in my own access token and local file path, and it successfully uploaded a non-empty file as expected for me.

You should check that your local file is non-empty and is being accessed successfully. For instance, check what the value of "$size" is for you, and make sure your "$fileURL", "$tempFilePath", and "$path" values are correct.
