Creating Php function to return css class

Question

In my wordpress template I am changing div class according to wordpress option setting values. I have multiple template /pages , so instead of repeating the php code on each template page, I want to create a function to return variable css class( $div here).

Wordpress option setting gives 2 variables: $pagewidth & $pagecolor .

PHP:

 <?php
    $pagewidth = 'big'; //big,small or tinny
    $pagecolor =  'white'; //white or black

    $divclass = array();
    $divclass = array($pagewidth,$pagecolor );
    $div = $divclass['0'].'-'.divclass['1'].'-box';
?>

css:

.big-white-box{width:100%;height:100%;background:url(images/big-white.png) repeat;}

.big-black-box{width:100%;height:100%;background:url(images/big-black.png) repeat;}

.small-white-box{width:100%;height:100%;background:url(images/small-white.png) repeat;}

.small-black-box{width:100%;height:100%;background:url(images/small-black.png) repeat;}

.tinny-white-box{width:100%;height:100%;background:url(images/tinny-white.png) repeat;}

.tinny-black-box{width:100%;height:100%;background:url(images/tinny-black.png) repeat;}

HTML:

<div class="<?php echo $div; ?>" >


<!--content-goes-here--->
</div>

Help me to create a php function which return css variable $div .

Havnt test it but something like this?

function getTemp( $WPtemplate , $pagewidth, $pagecolor ){
    $divclass = array();
    if( $WPtemplate == 1 ){
        $divclass = array($pagewidth,$pagecolor );
        $div = $divclass['0'].'-'.$divclass['1'].'-box';
        return $div;
