PHP preg_match_将所有大字符串按递增键分组=>；价值观

运行PHP7.1.5时，我有一个长字符串输出，我用

preg\u match\u all

进行分组。我试图将每个输出组放入一个新数组

key=>value

。例如，我有一个长字符串，如下所示：

$string = (
Name: John Doe
Address: 123 Main St
City: Chicago
State: IL
Zip: 60021
Name: Jane Smith
Address: 123 State Ave
City: Boston
State: MA
Zip: 02501
Name: John Doe
Address: 123 Main St
City: Chicago
State: IL
Zip: 60021
)

preg|u match|u all（'！（名称。*|地址。*|城市。*|州。*|邮编。*）！'，$string，$results）

这将提取信息，但是，所有信息都包含在一个键下的
$results
数组中。而不是此输出：

Array (
0 =>
    [0] => Name: John Doe
    [1] => Address: 123 Main St
    [2] => City: Chicago
    [3] => State: IL
    [4] => Zip: 60021
    [5] => Name: Jane Smith
    [6] => Address: 123 State Ave
    [7] => City: Boston
    [8] => State: MA
    [9] => Zip: 02501
    [10] => Name: John Doe
    [11] => Address: 123 Main St
    [12] => City: Chicago
    [13] => State: IL
    [14] => Zip: 60021
)

我需要在阵列中为每个捕获组提供以下输出：

Array (
    [0] =>
        [0]Name: John Doe
        [1]Address: 123 Main St
        [2]City: Chicago
        [3]State: IL
        [4]Zip: 60021

    [1] =>
        [0]Name: Jane Smith
        [1]Address: 123 State Ave
        [2]City: Boston
        [3]State: MA
        [4]Zip: 02501

     [2] =>
        [0]Name: John Doe
        [1]Address: 123 Main St
        [2]City: Chicago
        [3]State: IL
        [4]Zip: 60021
)

如您所见，第一个和第三个条目是相同的，我有很多重复条目。我可以通过运行
数组\u unique（$results）
来解决这个问题，如果数据中有已知数量的子元素（在本例中为5），则可以使用：

谢谢您的帮助。它起作用了。您是否有办法将
Zip
指定为数组中的最后一个键，而下一个键将是新的数组键？我可以看到这解决了第二个地址行的问题，它会抛出
array\u chunk
。当一个键重复时，它将通过搜索来计算每个数组的长度。你有一个很好的答案，但在运行了一些测试之后，不幸的是，它没有工作。通常情况下，还有第二条地址线，这会让一切都变得混乱。你还能想到什么？@INA2N我添加了一个解决方案，考虑到每个用户的元素数量可变。
