如何將數組值傳遞給php變量？

Question

我正在為我們當前的運輸管理系統開發一個非常小的更新。 我應該構建一個php腳本來使用USPS的AddressValidate API來實質上使用給定的地址，並使用USPS進行驗證。 當然，USPS會將格式正確的地址作為數組返回。 我的問題是，如何將返回值轉換為每個字段的變量？ （即地址1，地址2，城市等）然后按以下方式回顯結果

地址1： 123 Happyville Lane
城市：匹茲堡

我目前的劇本:(我的詳細信息已被*屏蔽）

<?php
$user = '****';
$xml_data = "<AddressValidateRequest USERID='$user'>" .
"<IncludeOptionalElements>true</IncludeOptionalElements>" .
"<ReturnCarrierRoute>true</ReturnCarrierRoute>" .
"<Address ID='0'>" .
"<FirmName />" .
"<Address1>123 happyville lane</Address1>" .
"<Address2></Address2>" .
"<City>columbus</City>" .
"<State>ohio</State>" .
"<Zip5></Zip5>" .
"<Zip4></Zip4>" .
"</Address>" .
"</AddressValidateRequest>";



$url = "http://production.shippingapis.com/ShippingAPI.dll?API=Verify";


    //setting the curl parameters.
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    // Following line is compulsary to add as it is:
    curl_setopt($ch, CURLOPT_POSTFIELDS,
                'XML=' . $xml_data);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 300);
    $output = curl_exec($ch);
    echo curl_error($ch);
    curl_close($ch);


print_r('<pre>');
print_r($array_data);
print_r('</pre>');
echo PHP_EOL;

返回的數組如下：

Array
(
    [Address] => Array
        (
            [@attributes] => Array
                (
                    [ID] => 0
                )

            [Address2] => 123 HAPPYVILLE LANE
            [City] => COLUMBUS
            [State] => OH
            [Zip5] => 12345
            [Zip4] => 1849
            [DeliveryPoint] => 18
            [CarrierRoute] => AC016
        )

)

Answer 1

echo "Address1: ".$array_data["Address"]["Address2"]."<br>";
echo "City: ".$array_data["Address"]["City"] //wrong city in example :P

應該做的伎倆或如果有更多的地址：

foreach($array_data as $key=>$address){
    $address2=$array_data["Address"]["Address2"];//if you need the assignment
    echo "Address1: ".$address2."<br>";
    echo "City: ".$array_data["Address"]["City"] //wrong city in example :P
}
