Check for an int and than loop again.
PHP
foreach($array as $key => $innerArray) {
if(is_int($key)) {
foreach($innerArray as $innerKey => $innerValue) {
echo $innerValue['applicable_states'];
}
}
}
Try this for Smarty:
{foreach from=$array key=key item=innerArray}
{if is_int($key)}
{foreach from=$innerArray key=innerKey item=innerValue}
{$innerValue.applicable_states}
{/foreach}
{/if}
{/foreach}
