How to change the 403 Forbidden page on Apache to your own?

Question

Apache HTTP Server

How can I replace the 403 Forbidden page, on Apache under Debian, with my own, in HTML/PHP format? And is this even possible?
Since you need to install a stub on the site, and so that it is described what to do in order to enter the site, and to give the code 403

Answer 1

At the root of the site, you need to create a file called .htaccess and enter the following line into it, indicating the file that is called when an error occurs 403
ErrorDocument 403 /error/403.php
In the same way, you can display a regular message, a la
ErrorDocument 403 '403 error'
