Question

我有以下数组：

数组（[@attributes] =＆gt;数组（[版本] =＆gt; 010 [发布] =＆gt; 006） [标题] =＆gt;数组（[To] =＆gt; 6891118750001 [From] =＆gt; 9911557 [MessageID] =＆gt; 306b197fff044421b31c0a2a15e356c1 [RelatesToMessageID] =＆GT;分辨率[SentTime] =＆gt; 2014-09-16T12：19：50.8Z [安全] =＆gt; Array（[Sender] =＆gt; Array（[TertiaryIdentification] =＆gt; 165）[Receiver] =＆gt; 数组（[TertiaryIdentification] =＆gt; 2341））[RxReferenceNumber] =＆gt; RxRef＃REFREQ 2.1 [PrescriberOrderNumber] =＆gt; 13）[Body] =＆gt;阵列（ [RefillRequest] =＆gt;数组（[Pharmacy] =＆gt;数组（[Identification] =＆gt; 数组（[NCPDPID] =＆gt; 9911557 [NPI] =＆gt; 1801849179）[StoreName] =＆gt; CA 药房10.6MU [地址] =＆gt;数组（[AddressLine1] =＆gt; 65432赤霞珠转[城市] =＆gt;索诺玛[州] =＆gt; CA [ZipCode] =＆gt; 95476） [CommunicationNumbers] =＆gt;数组（[Communication] =＆gt;数组（[Number] =＆GT; 7075557071 [资格] =＆gt; TE）））[Prescriber] =＆gt;数组（[Identification] =＆gt;数组（[NPI] =＆gt; 1234567893）[名称] =＆gt;数组（ [LastName] =＆gt;杰斐逊）[地址] =＆gt;数组（[AddressLine1] =＆gt; 5555 Labelle Lane [City] =＆gt;盖瑟斯堡[州] =＆gt; MD [ZipCode] =＆gt; 20877） [CommunicationNumbers] =＆gt;数组（[Communication] =＆gt;数组（[0] =＆gt; 数组（[Number] =＆gt; 3105551515 [Qualifier] =＆gt; TE）[1] =＆gt;阵列（ [编号] =＆gt; 3015551516 [资格] =＆gt; FX））））[患者] =＆gt;阵列（ [姓名] =＆gt;数组（[LastName] =＆gt; Li [FirstName] =＆gt; Ci）[性别] =＆gt; ü [DateOfBirth] =＆gt;数组（[Date] =＆gt; 1923-10-18）） [MedicationPrescribed] =＆gt;数组（[DrugDescription] =＆gt; ZIOPTAN 0.0015％眼科溶液[DrugCoded] =＆gt;数组（[ProductCode] =＆gt; 00006393130 [ProductCodeQualifier] =＆gt; ND）[数量] =＆gt;阵列（ [值] =＆gt; 1 [CodeListQualifier] =＆gt; 38 [UnitSourceCode] =＆gt; AC [PotencyUnitCode] =＆gt; C54702）[方向] =＆gt; D [Substitutions] =＆gt; 0 [WrittenDate] =＆gt;数组（[日期] =＆gt; 2014-04-01）） [MedicationDispensed] =＆gt;数组（[DrugDescription] =＆gt; ZIOPTAN 0.0015％眼科溶液[DrugCoded] =＆gt;数组（[ProductCode] =＆gt; 00006393130 [ProductCodeQualifier] =＆gt; ND [DrugDBCode] =＆gt; 1244616 [DrugDBCodeQualifier] =＆gt; SBD）[数量] =＆gt;数组（[Value] =＆gt; 1 [CodeListQualifier] =＆gt; 38 [UnitSourceCode] =＆gt; AC [PotencyUnitCode] =＆gt; C54702）[方向] =＆gt; D [Substitutions] =＆gt; 0 [WrittenDate] =＆gt;排列（[Date] =＆gt; 2014-04-01）[LastFillDate] =＆gt;数组（[Date] =＆gt; 2014-04-02）））））版本= 010

但是当我用这段代码循环它时：

function displayArrayRecursively($arr, $indent='') {
    if ($arr) {
        foreach ($arr as $value) {

            if (is_array($value)) {

                displayArrayRecursively($value, $indent . '');
            } else {
                echo key($arr) . " = $value<br>";
            }
        }
    }
}

displayArrayRecursively($arrXml);

它会打印所有值，但不会关联所有正确的子集键名称。有什么想法吗？

谢谢！

不要使用key()函数，而是直接使用$key的变量foreach()（或任何名称）访问数组键。此外，你甚至没有使用变量$indent，所以我添加了你需要的代码片段。这是您正在寻找的功能：

function displayArrayRecursively($arr, $indent='')
{
    if ($arr)
        foreach ($arr as $key => $value)
            if (is_array($value))
                displayArrayRecursively($value, $indent.'--');
            else
                echo $indent.$key." = $value<br>";
}

在PHP中循环遍历数组和子集
