使用php foreach循环获取json解码数组

Question

我有一个json解码数组，如$ json = json_decode（$ curl_result）;如何使用foreach循环获取此数组，我想尽可能减少数组循环。你能编写我能访问这些值的正确代码吗？

数组如下所示

  Array
  (
    [SITEResponse] => Array
    (
        [@version] => 1.0
        [SoftwareProducts] => Array
        (
            [@numFound] => 408
            [@numReturned] => 10
            [@start] => 0
            [SoftwareProduct] => Array
            (
              [0] => Array
                  (
                    [Summary] => Array
                    (
                         [$] => summery of software.
                    )
                    [Requirements] => Array
                    (
                    )

                    [ContentIds] => Array
                    (
                    )

                    [CleverBridgeUrl] => Array
                    (
                    )

                    [BuyNowUrl] => Array
                    (
                        [$] => http://www.abc.com
                        [@type] => dl_buy_pub
                    )

                    [BetaRelease] => Array
                    (
                        [$] => false
                    )

                    [LinkURL] => Array
                    (
                    [$] => http://www.abc.com
                    )
                )       
            )
        )
    )
)

现在我想得到这个数组的每个值，但是如何???请帮忙 感谢。

$version = $json['SITEResponse']['@version'];
$numFound = $json['SITEResponse']['SoftwareProducts']['@numFound'];

foreach( $json['SITEResponse']['SoftwareProducts']['SoftwareProduct'] as $key=>$product ){
$Summary= $product['Summary']['$'];
$BuyNowUrl = $product['BuyNowUrl']['$'];
