File name removal is complex but its possible, but i do this by removing the extension of the file,
As my Filename is getvideo.php and i want http://localhost/streamcola/watch
So i change my file name to watch.php and remove that .php extension
This is done by creating a new file named .htaccess file. I place it with my watch.php file and code of that .htyaccess file is following
RewriteEngine On
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule !.*\.php$ %{REQUEST_FILENAME}.php [QSA,L]
and hence i get my desired URL..
