数组是动态的，可以使用7个或多或少的键，但第一个键永远不会改变。
Array
(
[0] => Array
(
[ProviderID] => 1010
[ProviderName] => HAMZEPOUR, SHOKOUFEH
)
[1] => Array
(
[ContactName] => ABC XYZ
[Address1] => New York
[AddressType] => Physical
)
[2] => Array
(
[ContactName] => ABC XYZ
[Address1] => New York
[AddressType] => Billing
)
[3] => Array
(
[ContactName] => ABC XYZ
[Address1] => New York
[AddressType] => Mailing
)
[4] => Array
(
[AlgorithmID] => 1
[AlgoTitle] => Retro-Term
)
[5] => Array
(
[AlgorithmID] => 2
[AlgoTitle] => Modifier 25 errors
)
[6] => Array
(
[HoldType] => HoldType
[StatusID] => 1
)
[7] => Array
(
[HoldType] => HoldType
[StatusID] => 1
)
[8] => Array
(
[HoldType] => Hold
[StatusID] => 2
)
)
我需要将其更改为：
Array
(
[ProviderInfo] => Array
(
[PORAProviderID] => 1010
[ProviderName] => HAMZEPOUR, SHOKOUFEH
)
[ProviderAddress] => Array
(
[Physical] => Array
(
[ContactName] => ABC XYZ
[Address1] => New York
[AddressType] => Physical
)
[Billing] => Array
(
[ContactName] => ABC XYZ
[Address1] => New York
[AddressType] => Billing
)
[Mailing] => Array
(
[ContactName] => ABC XYZ
[Address1] => New York
[AddressType] => Mailing
)
)
[ProviderAlgorithm] => Array
(
[0] => Array
(
[AlgorithmID] => 1
[AlgoTitle] => Retro-Term
)
[1] => Array
(
[AlgorithmID] => 2
[AlgoTitle] => Modifier 25 errors
)
)
[ProviderException] => Array
(
[0] => Array
(
[HoldType] => HoldType
[StatusID] => 1
)
[1] => Array
(
[HoldType] => HoldType
[StatusID] => 1
)
[2] => Array
(
[HoldType] => Hold
[StatusID] => 2
)
)
)
第一个数组是我从db获取的结果，因为SP有四个结果集，我想按照第二个例子中的方式组织数组。
我试过这样做：
$search_array = $array;
$countb = count($search_array);
$counta = count($search_array) - 1;
//echo $countb;
$key_search = array('AlgorithmID', 'PORAProviderID', 'ContactName', 'HoldType');
$key_new = array('ProviderAlgorithm', 'ProviderInfo', 'ProviderAddress', 'ProviderException');
$b = 0;
while ($b <= $countb) {
$a = 0;
while ($a <= $counta) {
if (array_key_exists($key_search[$b], $search_array[$a])) {
$array[$key_new[$b]] = $array[$a];
unset($array[$a]);
// $a=$a-1;
}
$a++;
}
$b++;
}
这就是我得到的：
Array
(
[ProviderAlgorithm] => Array
(
[AlgorithmID] => 2
[AlgoTitle] => Modifier 25 errors
)
[ProviderInfo] => Array
(
[PORAProviderID] => 1010
[ProviderName] => HAMZEPOUR, SHOKOUFEH
)
[ProviderAddress] => Array
(
[ContactName] => ABC XYZ
[Address1] => New York
[AddressType] => Mailing
)
[ProviderException] => Array
(
[HoldType] => HoldType
[StatusID] => 1
)
)

为什么不使用foreach遍历第一个数组，然后使用开关来检测期望的键 - ＆gt;值对的类型：
编辑：紧接下面的代码是错误的。在此代码下方添加了正确的答案。
<?php
$newArray = array();
foreach($array as $arr) {
$keys = array_keys($arr);
switch($keys[0]) {
case "PORAProviderID":
if(!isset($newArray["ProviderInfo"])) {
$newArray["ProviderInfo"] = array();
}
$newArray["ProviderInfo"]["PORAProviderID"] = $arr[0];
$newArray["ProviderInfo"]["ProviderName"] = $arr[1];
break;
case "ContactName":
if(!isset($newArray["ProviderAddress"])) {
$newArray["ProviderAddress"] = array();
}
$newArray["ProviderAddress"][$arr[2]] = array();
$newArray["ProviderAddress"][$arr[2]]["ContactName"] = $arr[0];
$newArray["ProviderAddress"][$arr[2]]["Address1"] = $arr[1];
$newArray["ProviderAddress"][$arr[2]]["AddressType"] = $arr[2];
break;
case "AlgorithmID":
if(isset($newArray["ProviderAlgorithm"])) {
$count = count($newArray["ProviderAlgorithm"]);
} else {
$newArray["ProviderAlgorithm"] = array();
$count = -1;
}
$count++;
$newArray["ProviderAlgorithm"][$count] = array();
$newArray["ProviderAlgorithm"][$count]["AlgorithmID"] = $arr[0];
$newArray["ProviderAlgorithm"][$count]["AlgoTitle"] = $arr[1];
break;
case "HoldType":
if(isset($newArray["ProviderException"])) {
$count = count($newArray["ProviderException"]);
} else {
$newArray["ProviderException"] = array();
$count = -1;
}
$count++;
$newArray["ProviderException"][$count] = array();
$newArray["ProviderException"][$count]["HoldType"] = $arr[0];
$newArray["ProviderException"][$count]["StatusID"] = $arr[1];
break;
}
}
?>
我确信这可以超级简化，但我要在这里理解而不是效率。使用此方法，您可以检查算法和异常，并且不会期望记录数量的任何长度或限制。
编辑：修正了几个错误和问题。我不确定为什么PHP在使用foreach时不会为数组编制索引 - 我可能需要了解我的PHP函数。我为这种困惑道歉。我将离开上面的原始解决方案，以显示不该做的事情。

我是StackOverflow的新手，我必须为造成这么糟糕的第一印象而道歉。

在答案@ J.Michieli中，他说他的解决方案可以超级简化，我这样做是为了简化流程。此函数可用于n长度
