It's easier to interact with PHP with AJAX. But why not send the username through the URL and retrieve the value using the _GET variable in PHP? If the script requires JavaScript enabled to work, then just go all out AJAX.

yes wehave same problem as above.

we have a image and we have to put src of that img in session of php through onclick() event of img in javascript.

Java is run on the client, Php on the Server...Accordingly the only way to do that interaction, is to use something which both client and server do understand ... Cookies...

Just convert Java variables into cookies and let php read them  or viceversa convert php variables in Cookies and let java read them.

One problem arising... Time ;-( , the conversion from Cookie to Java and Cookie to php requires that the cookie is posted, or by pressing a hyperlink or by submitting a POST / GET.

So beware in that coding you'll loose the actual cycle and get it only the next one after the post.

The only true way to get php to understand javascript is with ajax.You make javascript send an ajax request to your php script.Your problem is because php is a server-sided code. Javascript is client-sided.So php will act the same way on all computers. Javascript won't.
