Multidimensional Arrays

I'm trying to submit multiple values to a variable within an <option> tag by using a value such as value="this,that" There are multiple <select> statements on this form each counting up from 1 using $count and $listings as such. <? $count = 1; $listings = 3 while ($count <= $listings) {?> <select name="listings[<? echo $count; ?>" value="1"> <option value="this,that">This and That <option value="that,this">That and This <? $count++; } ?> On the recieving side I'm parsing many instances of these using the following method $count = 1; $listings = 3; while ($count <= $listings) { $listing['$count'] = $_POST['listing[$count]']; } This example works fine if I need to get the full value (this,that) or (that,this). What I'd like to do is break this into a multidimensional array so I have approximately the following depending on what they choose for each example. $listing[1][0] = this $listing[1][1] = that $listing[2][0] = that $listing[2][0] = this Hopefully this example is clear enough that someone will understand what I'm doing. I tried the following with no luck. $listing['count'] = $_POST['listing[count]']; $listing['$count'] = explode(",", $listing['$count']); Any takers? Thanks. Ed
