What steps can be taken to troubleshoot the "failed file count" and "bad server response" messages during file uploads exceeding 2GB in PHP?

The "failed file count" and "bad server response" messages during file uploads exceeding 2GB in PHP can be caused by limitations set in the PHP configuration file. To troubleshoot this issue, you can increase the values of the following PHP configuration settings: `upload_max_filesize`, `post_max_size`, and `max_input_time`.

// Increase upload_max_filesize, post_max_size, and max_input_time
ini_set('upload_max_filesize', '5G');
ini_set('post_max_size', '5G');
ini_set('max_input_time', 300);
