How do I find the current browser window width in pixels?

Question

I'm writing a PHP script that will use the current browser
window width
and height, but I don't know how to find that. Is there some
way to
capture the width and height of the current window in pixels?
TIA

Thanks Micha, you certainly may ask why.
I posted a message some time ago in the appdev forum about
the Recordset
Paging server behavior being geared toward use with tables. I
was
frustrated because I wanted to do something with repeated
div's in a
liquid site. But the Recordset Paging s.b. locks the number
of records
per page to a fixed number. I'm trying to figure out how to
make the
records per page a variable that's determined by the window
width. I've
created a liquid site with a products page that contains both
text and
thumbnail product images. The text occupies 2/3 of the width
of the
window, and the div container that holds the floated div
thumbnails I
want to account for the other third. The thumbnail div's are
produced by
a WHILE statement and I want them to be paged based on the
number of
div's that will fit within a container that occupies a
percent of the
browser window width. Here's what I've got so:
$window_size_wide = ; // Current browser window width in px
$window_size_tall = ; // Current browser window height in px
$thumb_cont_wide = $window_size_wide * .3; // 30% of window
width incl.
padding in px
$thumb_cont_tall = $window_size_tall * .4; // 40% of window
height incl.
padding in px
$thumb_size_wide = 100; // thumbnail div width incl. margins
in px
$thumb_size_tall = 100; // thumbnail div height incl. margins
in px
$no_thumbs_wide =
ceil(($thumb_cont_wide/$thumb_size_wide)-1);
$no_thumbs_tall =
ceil(($thumb_cont_tall/$thumb_size_tall)-1);
$records_per_page = ($no_thumbs_wide * $no_thumbs_tall);
$offset = ($thispage - 1) * $records_per_page;
$total_pages = ceil($total_records/$records_per_page);
etc.
What I don't know is how to find the current window width or
height. I
would also like to know if the $thumb_cont_wide and the
$thumb_cont_tall
can be determined in some way based on the div size generated
through my
CSS. In other words, I don't want to declare the percent of
height and
width in this script, I want to declare it only in my CSS and
have it
determined by the browser window width and height. The only
element I
want to hard code is the size of the thumbnails as they will
always be
the same. It seems to me that something like this could be
done to make
recordset paging scalable to match a scalable web page.
So the question is, can I define a PHP variable based on a
Javascript
variable? If so, how? If not, how can I accomplish this? Is
this just
not possible?
Thanks for your help.
