Hello guys can any one help me in this issue i want to rewrite my urls can u tell me how can i rename http://mysite.com/Led/index.php?d=java//2012_ap to http://mysite.com/Led/java/2012-ap.php or plese help me
please give me a modrewrite code for this

Seriously...I refuse to give out the link to the mod_rewrite docs any more. Do a search of this forum, apache's docs, google...etc.

Orr just wait for someone to hand you your work on a silver platter.

Here's a nice simple tutorial, maybe it'll help you -> http://articles.sitepoint.com/article/guide-url-rewriting
or

Really though, mattle is right - google is your friend.
