SimpleXMLElementを繰り返し、郵便番号値を取得します。

Question

Google Geocode v3 API XMLレスポンスから郵便番号を抽出しようとしています。私が抱えている困難は、時にはpostal_codeの値が6番目のaddress_elementに、時には7番目に含まれていることです。ここで私はあなたがPOSTAL_CODEがaddress_component配列の6番目の要素であることがわかりますとして、このサンプル応答で働いていますXMLレスポンスです：

SimpleXMLElement Object

私はこれを試していないが、私はそれが動作するはずだと思います。

$address = $array->result[0]->address_component; 
$postal_code = ''; 
foreach($address as $adr){ 
    if($adr->type == 'postal_code'){ 
     $postal_code = $adr->long_name; 
    } 
}
