Are there alternative functions to header() for direct redirection in PHP?

When using the `header()` function in PHP for redirection, it is important to note that it must be called before any output is sent to the browser. If you encounter issues with using `header()` for redirection, you can consider using alternative methods such as using JavaScript to redirect or using the `meta` tag in HTML for automatic redirection.

// Alternative method for redirection using JavaScript
echo "<script>window.location.replace('https://www.example.com');</script>";

// Alternative method for automatic redirection using meta tag
echo "<meta http-equiv='refresh' content='0;url=https://www.example.com'>";
