If you are planing to develop a real time web application or a web based tool, you may use javascripts or action scripts. In javascripts you can only develop only client side applications. If you want to develop a server side application, like a registration form or login page, then you need to use server side scripting language to do that. Most popular server side scripting languages are PHP,ASP.NET and JSP.
The main disadvantage of the server side scripting languages is you need to submit the entire web page to the server.
Is there any solution ?

2. You should include the path of the
jquery.js inside <script> tags.
3. make a variable which include the path of
.php file. (line 5)

jquery.js which makes a html post to the php script.
5. You may see a few parameters in that function.
url - which explained before
name - you can directly call
$_POST['name'] in php. It will gives the value of
param
param - the parameter should pass to this function when it calls.
mname - a variable which takes the returning value in php script.

Div1 is the id of a div tag and
by calling html().show() function, it's inner html should assign with mname value.
This is the php code, which gets the input from the html page and return the string to the html page. (strrev() is the function which reverse a string).
