Sorry to keep on with this but think I am almost there.
I have set up the .htaccess file like this
RewriteRule ^blogarticle/([^/]*)\.php$ /blog-article.php?zzBlog=$1 [L]
Where, /blog-article.php?zzBlog=5 is re-written to this /blogarticle/5.php which is great....
My next question is, and am not sure if this is something that I need to speak to you guys about or someone on the apache forum, but how would I go about taking the 5 and replacing it with the actual title of the article?
