如何调用前面有@的数组值，如@activePropertyCount[]
尝试使用echo$value[HotelList][@activePropertyCount]；
有一个属性与数组关联，例如HotelSummary-如果是，我该如何调用它？
代码看起来像：
Array
(
[HotelListResponse] => Array
(
[customerSessionId] => 0ABAAABC-3DA4-3914-B842-7B403B905AF7
[numberOfRoomsRequested] => 1
[moreResultsAvailable] => 1
[cacheKey] => 793da43:14b847b403b:-5a8d
[cacheLocation] => 10.186.170.188:7300
[cachedSupplierResponse] => Array
(
[@supplierCacheTolerance] => MED_ENHANCED
[@cachedTime] => 0
[@supplierRequestNum] => 931
[@supplierResponseNum] => 20
[@supplierResponseTime] => 1501
[@candidatePreptime] => 314
[@otherOverheadTime] => 53
[@tpidUsed] => 5110
[@matchedCurrency] => true
[@matchedLocale] => true
)
用引号括起数组键：
echo $value['HotelList']['@activePropertyCount'];
即使您不需要特殊字符，也应该这样做，因为否则PHP首先要查找一个常量，如果找不到，就会返回到字符串。虽然这在HotelList上有效，但在@activePropertyCount上无效，因为如果不加引号，@将是一个语法错误。
