passing a JS var to PHP

I have a JS var and I want to pass it to PHP for a mySQL select


function foo (boo){

<?php
$sql = "SELECT boogie FROM man where id = boo";
$result = mysql_query($sql);
?>

...

}



can boo be passed to PHP? and if so, how?

you could use window.location to add querystring to url and use $_GET['varname'];
simple :)

there are no URLs here... this code is all in one script ...

I have a JS var which I pass into a function

I want to use that same var in PHP inside this function

If you're trying to use javascript to pass to some PHP on the same page "you can't" without reloading the same page. PHP (server-side) is finished parsing by the time javascript(client-side) comes into play.

However if you want to use PHP variable in javascript, you can just echo it out to the JS.

hence the window.location post above :)
