You can use this lookahead based regex:

\d+(?=\D*$)

RegEx Demo

.htaccess:

Inside your root .htaccess you can use this rewrite rule:

RewriteEngine On

RewriteRule ^directoryname/.*?(\d+)\D*$ /detail-page?id=$1 [L,QSA,NC,R]

May be this could be one way to do it:

(\d+).html$
  • \d+ match a digit [0-9]

Online Demo 1

and this is another way:

\d+(?=\.html$)
  • (?=.html$) It is a positive lookahead - it assert that the regex below can be matched if it contains at end($) a .html

Online Demo 2
