How can PHP error reporting settings be adjusted to troubleshoot issues with file processing?

To troubleshoot issues with file processing in PHP, you can adjust the error reporting settings to display any errors that may be occurring during the process. By setting error reporting to E_ALL, you can ensure that all errors, warnings, and notices are displayed, helping you identify and resolve any issues with file processing.
