How can beginners avoid common pitfalls when using header() function in PHP?

Beginners can avoid common pitfalls when using the header() function in PHP by ensuring that no output is sent to the browser before calling the function, and by using the exit() function immediately after setting the header to prevent any further output. It's also important to check for any whitespace or characters before the opening <?php tag, as they can cause headers to be sent prematurely. 

&lt;?php
ob_start(); // Start output buffering
// Code goes here
header(&#039;Location: https://www.example.com&#039;);
ob_end_flush(); // Flush output buffer
exit(); // Terminate script
?&gt;
