Build Select statement in Form from array using jQuery or PHP?

Hi,
My script below returns an array of countries and codes, can I build a select statement in a form from this array using jQuery or PHP?

Array ( [countries] => Array ( [country] => Array ( [0] => Array ( [code] => AF [name] => AFGHANISTAN ) [1] => Array ( [code] => AL [name] => ALBANIA ) [2] => Array ( [code] => DZ [name] => ALGERIA ) [3] => Array ( [code] => AS [name] => AMERICAN SAMOA ) [4] => Array ( [code] => AO [name] => ANGOLA ) [5] => Array ( [code] => AI [name] => ANGUILLA ) [6] => Array ( [code] => AG [name] => ANTIGUA AND BARBUDA ) ..

<script type="text/javascript">
var post_str = { url: "https://auspost.com.au/api/postage/country.json" };
       $("#postage_costs").html('Getting Country List...'); 
	 
				$.ajax({ 
					type: "POST",    //define the type of ajax call (POST, GET, etc) 
					url: "../includes/auspost_api_countries.php",   //The name of the script you are calling 
					
					data: post_str,    //Your data you are sending to the script 
					success: function(msg){ 
					
					alert (msg)				
					
					
					} 
				}); 

   
   }

</script>

<select name="select_country">
  <option selected="selected">Please Select Country</option>
