In what situations is it recommended to use file_get_contents() or readfile() instead of include or require in PHP for outsourcing common elements like Header, Nav, and Footer?

When outsourcing common elements like Header, Nav, and Footer in PHP, it is recommended to use file_get_contents() or readfile() instead of include or require when you want to include the content of the file directly without executing any PHP code within it. This is useful for including static HTML content or files that do not contain PHP logic. 

// Example using file_get_contents() to include common elements like Header, Nav, and Footer
echo file_get_contents('header.html');
echo file_get_contents('nav.html');
// Main content goes here
echo file_get_contents('footer.html');
