What are common pitfalls when using header location in PHP for redirection?

Common pitfalls when using header location for redirection in PHP include not using an absolute URL, not calling exit or die after setting the header, and attempting to set headers after output has already been sent. To avoid these issues, make sure to use absolute URLs for redirection, call exit or die after setting the header, and ensure that no output is sent before setting headers.
