Question

我有以下数组输出：

[38] => x._domainkey    14400   IN  TXT ( "v=DKIM1; k=rsa; p=MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEApYA+ELn4SxsERDFgUB9pUnB4PjbcUlSJoLHAlCq1MLVA3NxgLKSAz+lSczyMH97Y/xOpJf1X1LSoGgNh5GVRn0t"
[39] =>                     "pm1QOPfKbNHx8VMNn4L/KZSPGFyySDUK/UPnF1QoMckoU5a/LgtI8x1ttry5oySDTY9KprVAf92uK6pOFQJA3QlzV2P+R4tx/zho5KlDHmc8YKjL7rLjgQVX7GUBi9cHr0+BQdVFgFL8SwBY8fn/CQ"
[40] =>                     "42JMsEWcMjjEkbAwi9yscGQoTih+kctjr4W8LDF28vyJixozbaFpG8pJ+jGDAho+Zjt/XReOZQP0h51Y8md3/x/F0+gST4mn0mCskNtIQIDAQAB" )

我怎样才能在建造之后得到这个？

[38] => x._domainkey    14400   IN  TXT ( "v=DKIM1; k=rsa; p=MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEApYA+ELn4SxsERDFgUB9pUnB4PjbcUlSJoLHAlCq1MLVA3NxgLKSAz+lSczyMH97Y/xOpJf1X1LSoGgNh5GVRn0tpm1QOPfKbNHx8VMNn4L/KZSPGFyySDUK/UPnF1QoMckoU5a/LgtI8x1ttry5oySDTY9KprVAf92uK6pOFQJA3QlzV2P+R4tx/zho5KlDHmc8YKjL7rLjgQVX7GUBi9cHr0+BQdVFgFL8SwBY8fn/CQ42JMsEWcMjjEkbAwi9yscGQoTih+kctjr4W8LDF28vyJixozbaFpG8pJ+jGDAho+Zjt/XReOZQP0h51Y8md3/x/F0+gST4mn0mCskNtIQIDAQAB" )

一条规则。

我努力尝试获得多个数组的输出，但不是一条规则：

Array ( 
  [0] => x._domainkey 
  [1] => 14400 
  [3] => TXT 
  [4] => ( "v=DKIM1; k=rsa; p=MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEApYA+ELn4SxsERDFgUB9pUnB4PjbcUlSJoLHAlCq1MLVA3NxgLKSAz+lSczyMH97Y/xOpJf1X1LSoGgNh5GVRn0t" 
) 

Array ( 
  [0] => 
  [1] => 
  [2] => 
  [3] => 
  [4] => 
  [5] => "pm1QOPfKbNHx8VMNn4L/KZSPGFyySDUK/UPnF1QoMckoU5a/LgtI8x1ttry5oySDTY9KprVAf92uK6pOFQJA3QlzV2P+R4tx/zho5KlDHmc8YKjL7rLjgQVX7GUBi9cHr0+BQdVFgFL8SwBY8fn/CQ" 
) 

Array ( 
  [0] => 
  [1] => 
  [2] => 
  [3] => 
  [4] => 
  [5] => "42JMsEWcMjjEkbAwi9yscGQoTih+kctjr4W8LDF28vyJixozbaFpG8pJ+jGDAho+Zjt/XReOZQP0h51Y8md3/x/F0+gST4mn0mCskNtIQIDAQAB" ) 
)

我希望[4]之后的一个规则上的数组[5]，这可能吗？

Answer 1

在进行一些清理（删除引号，括号等）之后，您需要连接元素。在这种特定情况下，我从第一个元素中删除了最后一个字符（要删除尾随引号，也可以是class QuestionFilter(FilterSet): difficulty_avg__gt = django_filters.NumberFilter(name='difficulty_avg', lookup_expr='gt') difficulty_avg__lt = django_filters.NumberFilter(name='difficulty_avg', lookup_expr='lt') class Meta: model = models.Question fields = {'difficulty_avg': ['lt', 'gt']} class QuestionViewSet(ModelViewSet): queryset = models.Question.objects.annotate(difficulty_avg=Avg('difficulty_questions__difficulty'))或trim()），并使用trim()删除引号和尾随引号在接下来的两个元素上。

如果这三个元素的位置是动态的，首先搜索一个可能对您的用例唯一的值（在我的示例中，我使用trim()）并使用该键作为连接的基础：< / p>

domainkey

这不是数组合并，它是字符串连接。

$array[38] .= $array[39] . $array[40]; // combine the 3 lines into one
array_splice($array, 39, 2); // remove the continuation lines

只要行在值之前包含(，您就需要执行此操作。你必须得到所有的行，直到匹配)并连接它们。

三个数组之间的数组合并
