如何阵列转换成XML标签

Question

Array([promo_code] => Array 
     (
      [0] => promo_code is required 
     ) 

    [first_name] => Array 
     (
      [0] => first name is required 
     ) 

    [last_name] => Array 
     (
      [0] => last name is required 
     ) 

    [address] => Array 
     (
      [0] => address is required 
     ) 

    [city] => Array 
     (
      [0] => city is required 
     ) 
); 

我上面阵列，我想它显示为

<?xml version=1.0?> 
<Result> 
<promo_code>promo_code is required</promo_code> 
<last_name>last_name is required</last_name> 
<address>address is required</address> 
<city>city is required</city> 
</Result> 

请指导谢谢提前
