Redirect to index.php of requested subfolder

Question

I need to redirect to index.php of whichever directory is requested.

So I need:

http://www.site.com/folder/files/hello.php

To Redirect to:

http://www.site.com/folder/files/index.php

And also same for any subfolders:

http://www.site.com/folder/files/pages/other/hello.php

Redirect to:

http://www.site.com/folder/files/pages/other/index.php

Answer 1

The (technically) right way

Construct a URI consisting of the current scheme (http / https / etc), hostname and path of the current file and issue a Location header.

$url = sprintf('%s://%s%s/index.php',
    $_SERVER['SERVER_PORT'] == 80 ? 'http' : 'https',
    $_SERVER['SERVER_NAME'], rtrim(dirname($_SERVER['PHP_SELF']), '/'))
header("Location: $url");
exit;

This is because a location header URI should be complete and absolute. Relative URIs are technically not allowed however there is a draft specification set to change this.

The pragmatic way

Just issue a relative Location header as it will most probably work.

header('Location: index.php');
exit;
