Before running this you have to install "PhpMyAdmin"or "wamp"or "xampp" in your pc. then open any browser and write in Url bar "Localhost/phpmyadmin" and here we make our Database,
Now open one more tab in browser and open "localhost/Filename". we all know the ip address of localhost is 127.0.0.1
In Php for printing anything we use  echo"statement". in thiscode i also perform the validation.
  
Code
 
- <?php  
-    mysql_connect("localhost","root","");  
-    mysql_select_db("DATABASE NAME");
