Why do you have such a strange array? It's not as easy to iterate through its values if it's counted in base two, you should alter $dtl_array through PHP into something easier to deal with first:


<?php
$dtl_array = generate_bizarre_array();

$cool_array = array();

$SoFdtl_array = count( $dtl_array );
for( $i = 0; $i < $SoFdtl_array; ++$i )
{
$SoFdtl_array_I_uom_array = count( $dtl_array[$i]['uom_array'] );
for( $j = 0; $j < $SoFdtl_array_I_uom_array; ++$j )
$cool_array[] = array( 'key' => $dtl_array[$i]['uom_array'][$j][0],
'value' => $dtl_array[$i]['uom_array'][$j][1] );
}

$sample->assign( 'coolness', $cool_array );
$sample->display( 'it.tpl' );
?>

(it.tpl:)
<select name="JohnDoe">
{foreach from=$coolness item="opt"}
<option value="{$opt.key}">{$opt.value}</option>
{/foreach}
</select>



This assumes that however you get that binary-indexed array, it comes from a dynamic source. Otherwise, the PHP code would be much simpler. {foreach} is also easier to use (IMO). I suggest you also throw in a {foreachelse} if this really is a dynamic source.
