Just fought through something like this today...
<form id="styles_saver" ...>
<input type="submit" onclick="save_styles();" />
</form>
<script type="text/javascript">
function save_styles(){
var div;
var styles_saver=document.getElementById('styles_saver');
foreach(divs as d){
div = divs[d];
styles_saver.innerHTML += '<input type="hidden" name="style["' + d
+ ']" value="' + div.style '" />';
}
styles_saver.submit();
</script>
This is all JS, obviously...

So now in the PHP part, to force this at least nominally on-topic, you
have a nice array in $_POST['styles'] with an index by div in order,
that you'd process like any $_POST value which is an array:
if (isset($_POST['styles']) && is_array($_POST['styles'])){
foreach($_POST['styles'] as $d => $style){
//do something with div's $style, indexed by $d
}
}
You could presumably get each div's id with div.id or somesuch, and
use that instead of 'd' above.
