How can developers troubleshoot and resolve header-related errors in PHP code?

To troubleshoot and resolve header-related errors in PHP code, developers can check for any whitespace or output before calling the header() function, ensure that the header() function is being called before any output is sent to the browser, and make sure that there are no syntax errors in the header function parameters. 

<?php
ob_start(); // Start output buffering

// Perform any operations here

header("Location: https://www.example.com"); // Redirect to the specified URL

ob_end_flush(); // Flush the output buffer
?>
