You can't. Javascript is executed in the browser, PHP is executed on the
server.
What are you trying to achieve, as maybe there is a better way to do it.

I have to disagree Ash, you can pass js variable values to PHP but only
through a page load. Then you could use $_REQUEST, $_POST, $_GET to retrieve
it. I have done this before.

And I am sure Ash does it on daily basis=2C the problem is the used therm: =
I want to *assign* ... not pass=2C assign!
I am quite sure that is what he meant=2C since I cannot count people readin=

All true, and probably appropriate to clarify the relationship between
php and js.
However, if the goal is to pre-set something in php land so you don't
have to pass it with your next page navigation, you could use ajax to
to pass the value to a simple php script that in turn updates a php
session variable, so that it is already set when you do your next real
page load.
You would still be "calling a page" technically, but your current
displayed page would remain in place and php would have the value
available on its next page load.

Very true. I really didn't intend to dismiss everything you said Ash. I
apologize for that. You were absolutely correct in your statement about not
being able to directly assign the value of a javascript variable to a PHP
variable. I just felt that your response would leave the reader to believe
that that wasn't any way to pass the value at all. In my attempt to throw my
two cents in I essentially did the same to your response. I'm afraid I left
some thinking I was dismissing your entire statement. Sorry about that.
Thank you,

Or you can also do this way:
on loading
[...]
echo "
value='".$myphpvar."'>";
[...]
echo "
onclick='javascript:recalculateValue();' value='Click Me!' ";
[...]
?>
once changed, you choose how to proceed, maybe executing any other js
funcion that use new value of/for the input, maybe submit the form an take
it from the request in the next page (in the server side, this time).
basicly is use hidden inputs as a container for php variables, and transform
through js.

really? I though the other way round was extremely simple:
echo ''=3B
why would you use hidden input=2C plus DOM to get data=2C etc=2C etc?

imagine you have an assoc. array that you encode with json and save in the
js var. Ok.
This way is perfect. But you can do less with this values than using my
solution. Important: Each case is different, and may be studied in
particular.
You can not pass this myPHPvar javascript var as an input in a form. if you
want to change its value and maintein it, must to use an static var, and
only can access to this values via javascript functions where an event is
invoked (in case you want to read or write values)
And I repeat: My solution is not the best, of course, but in many cases (for
my), mantaninance of data in hidden input and using DOM for accessing it,
allow an easiest dinamic treatment of data without reload a web page. Even
more if using jQwey or Prototype.

with all due respect=2C there is absolutely nothing you can do better or di=
fferently with an hidden input.
I can send and manage a JS var the same way you do via input=2C except I do=
not need to search a node=2C get it=2C and put it back every time I need t=
o modify that var.
Remote scripting=2C JSONP=2C Ajax are ways to do it since ages.
Persistence=2C if we are talking about refer the variable rather than recre=
ate it=2C is something not possible with or without the input=2C 'cause as =
PHP serialize/unserialize session vars=2C in JS you can save the var in JSO=
N format and recreate it for each page reload=2C unless you do not use ajax=
=2C but in that case we are talking about synchronization between a client/=
server mirrored variable status.
If you use Ajax for the entire client session=2C you need to update the var=
ialbe status only once on page unload and that's it.
If you want to change a user status step by step you use localStorage=2C Ge=
ars=2C or other technologies=2C unless you do jnot want to overload the ser=
ver with useless requests performed for each operation over the variable.

hello,
You can also try using AJAX technology to communicate with the server
side code that is your php :).

saeed:
Considering that js is client-side and php is server-side, you need
to pass the value via a communication mechanism between the two. Your
choices are the standard GET/POST or ajax.
