如何在打开的购物车中比较数组中特定索引的值

Question

i have an array $ results, which gives me following output when i do print_r on it.

Array ( 
    [0] => Array ( 
        [parent_geo_zone_id] => 3 
        [name] => UK VAT Zone 
        [shipping_pool_geo_zone_id] => 
        [email] => 
    ) 
    [1] => Array ( 
        [parent_geo_zone_id] => 4 
        [name] => UK Shipping 
        [shipping_pool_geo_zone_id] => 
        [email] => 
    ) 
    [2] => Array ( 
        [parent_geo_zone_id] => 5 
        [name] => Texas 
        [shipping_pool_geo_zone_id] => 5 
        [email] => [e-mail] 
    ) 
    [3] => Array ( 
        [parent_geo_zone_id] => 6 
        [name] => florida 
        [shipping_pool_geo_zone_id] => 6 
        [email] => [e-mail] 
    ) 
    [4] => Array ( 
        [parent_geo_zone_id] => 7 
        [name] => alaska 
        [shipping_pool_geo_zone_id] => 
        [email] => 
    ) 
)

I want to compare the following indexes

'parent_geo_zone_id' and 'shipping_pool_geo_zone_id ' 

like this

if($results->array['parent_geo_zone_id']==$results->array['shipping_pool_geo_zone_id '])

where ever these two ids are equal i want to send my checkbox value as checked to view other wise unchecked like this.

 foreach ($results as $result) {

            $this->data['geo_zones'][] = array(
                'geo_zone_id' => $result['parent_geo_zone_id'],
                'name'        => $result['name'],
                'email'       => $result['email'],

                'selected'    => isset($this->request->post['selected']) && in_array($result['geo_zone_id'], $this->request->post['selected'])

            );

I am using open cart.

You just can use such expression

if($result['parent_geo_zone_id'] === $result['shipping_pool_geo_zone_id'])
  {
  // any stuff for true
  } 
else
  {
  // any stuff for false
  }
