I have 2 page loader.php and index.php, i want to show page loader.php in index.php then dispear after 5 second from index.php without refresh or redirect ! ps : page not a div,sorry for my bad english.
In index.php, include the loader.php content into a div that you've styled to be full page and z-indexed above the rest. With Javascript, setTimeout for 5000 ms to hide the div.
A brief answer for a brief question.
