Are there any specific guidelines or resources for preventing header errors in PHP development?

Header errors in PHP development can be prevented by ensuring that no output is sent to the browser before calling the header() function to set HTTP headers. To avoid header errors, it is important to make sure that there are no spaces, line breaks, or any other output before calling header(). 

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

// Your PHP code here

ob_end_clean(); // Clean the output buffer without sending output

header("Location: https://www.example.com"); // Set HTTP header
exit; // Exit the script
?>
