Re: My uploaded files on Dropbox are 0 bytes/ empty.

$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;
}
