Some days ago I posted this link
http://www.cmswire.com/cms/industry-news/php-vs-java-vs-ruby-000887.php

and I noticed that guys didnt realise that from the link you can't actually be sure of the programming language used to build the site (some nonsense again from me, keep reading).
You might obviously think its php but if you build a site like this one I did

http://www.cameroonfootballers.com/profiles/showPublicProfile/27/alexandre-song-billong

from that link you can't tell if its php or java or C#. I built that site with php and there is no folder on the server root like profiles nor showpublicprofile (but profiles is an object and show public profile is profiles method like profiles->showpublicprofile).
So why do people create such links which have the title of stories in the link.
The answer is because Google will index such sites with a better understanding.
with a link like this

www.your-site.com/article.php?article_id=10&date=10008574

When google gets to that url linking to such a page, it stops indexing because their crawler might enter and endless loop.
so with Apache and .htaccess configurations you can make that link become something like this behind and actually still run on php

www.your-site.com/article.php/10/10008574

this way since the ? (question mark) is not in the url the google crawler will easily crawl and index your site.
so nowadays with[b] Apache Webserver's Mod_rewrite function and .htaccess[/b] you can build a site with java and make it have .php extension.
Next time Afam don't get this link

http://www.cmswire.com/cms/industry-news/php-vs-java-vs-ruby-000887.php

and boldly think its php, because only the site developer can tell you the technology used behind and I can use ruby on rails and my links show .php
hope it helps

so how do i do that. i really like that idea

hello Aphoe
its easy, if you are running apache webserver with php then you can easily do it by learning how to use .htaccess files.
these links will help you do that easily

hey but note that I tried tihs with Xampp server and it failed me but with phpdev it works well locally but on production (live) sites I havent found any problem

@mambenanje

The links were indeed helpful. Thanks for the lead.
