How do I redirect custom url using htaccess?

Question

I am migrating from Wordpress to a custom coded content management system and need help converting the old URLs using htaccess.

I have over 2000+ old articles with the following URL structure:

www.site.com/ID/post-title/

I need to redirect each post to a custom script that uses the post ID:

www.site.com/post.php?id=ID

Any help is greatly appreciated.

You may try this:

RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} ^/([^/]+)/?    [NC]
RewriteRule .* post.php?id=%1  [L,QSA]

It will map silently this:

http://www.site.com/ID/post-title/

To this:

http://www.site.com/post.php?id=ID

Where ID is not a fixed string but a variable that is passed as the id value to the script.
