Can anyone help me in this? how can I set my url this way?

Answer 1

I'll assume that institute IDs have to be integers - no letters or decimal points or anything.

# Turn on URL re-writing
RewriteEngine On

# Clean URLs for institutes.
RewriteRule ^institutes/([0-9]+)/?$   /institutes_desc.php?id=$1    [NC,L]

For further information, I refer you to Dave Childs' thorough introduction to URL rewriting.
