[RESOLVED] Form Select Multiple Dynamic Problem

[fontener]

<select id="property_zoning" multiple="multiple" name="zoning[]">
<?php echo showOptionsDrop($zoning_arr, '',$_SESSION["foo"]["zoning"]);?>
</select>

function showOptionsDrop($array, $multi=NULL, $selected=NULL){
        if($multi == NULL){
		$string = '<option value="">Select one</option>'."\n";
		} else {
		$string = '<option value="">None</option>'."\n";}
        foreach($array as $k => $v){
			$s=NULL;
			if($k == $selected || $v == $selected)
				{
					$s = ' selected="selected"';
				}
			$string .= '<option value="'.$k.'"'.$s.'>'.$v.'</option>'."\n";
        }
        return $string;
    }

So this function works terrific for a regular select input, however, with the multi select, it does not function with $selected as an array. I would like to implement something so that if $selected is an array, it iterates through. But when I attempted it, it just marked them all as selected.

And as always, I greatly appreciate the help. I'm sure it involves some type of recursion?

        foreach($array as $k => $v){ 
            $s=NULL; 
            if( is_array($selected) && ( in_array($k,$selected) || in_array($v,$selected) ) 
               {
                    $s = ' selected="selected"';
                }
            elseif($k == $selected || $v == $selected) 
                { 
                    $s = ' selected="selected"'; 
                } 
            $string .= '<option value="'.$k.'"'.$s.'>'.$v.'</option>'."\n"; 
        }

Thank you sir! I was making it out to be much harder than it should be.
