What are some alternative methods to redirect users to specific URLs in PHP other than using header() function?

When redirecting users to specific URLs in PHP, using the header() function is a common method. However, there are alternative methods to achieve this without directly using header(). One alternative method is using JavaScript to redirect users, which can be done by outputting a script that changes the window location. Another method is using HTML meta tags to automatically redirect users after a certain amount of time.

// Using JavaScript to redirect users
echo '<script>window.location.replace("https://example.com");</script>';

// Using HTML meta tags to redirect users
echo '<meta http-equiv="refresh" content="0;url=https://example.com">';
