How do I redirect users to another page using PHP?
Answer
Redirection in PHP can be done using the header() function. To setup a simple redirect, simply create an index.php file in the directory you wish to redirect from with the following content:
        < ?php header("Location: http://www.redirect.to.url.com/"); >
        
Where 'http://www.redirect.to.url.com/' is the URL you wish the users to be redirected too. This can also be a file, like so:
        
        
Files can be of anytime including but not limited to HTML, python, php, cgi, perl, and compiled cgi programs.
