我有一个阵列说：
$input = Array
(
[2] => Array
(
[message] => 1 file(s) do not conform to the xxx naming standards.
[type] => warning
[headers] => Array
(
[0] => Array
(
[name] => Package
[property] => zip
)
[1] => Array
(
[name] => Name
[property] => name
)
)
[rows] => Array
(
[0] => Array
(
[zip] => abcd.zip
)
)
)
[111] => Array
(
[message] => Invalid it is
[type] => error
[headers] => Array
(
[0] => Array
(
[name] => ID
[property] => id
)
[1] => Array
(
[name] => Title
[property] => title
)
[2] => Array
(
[name] => Zip
[property] => zip
)
)
[rows] => Array
(
[0] => Array
(
[id] => abcd
[title] => title
[zip] => abcd
)
)
)
)
然后我计算长度如下： $ length = count（$ this-＆gt; view-＆gt; feedback）; $ i = 0;
现在我正在运行一个foreach循环
foreach ($input as $operation)
{
if($operation['type'] == 'error')
{
$output = array_slice($operation, -$i, $length);
}
$i++;
}
上面的array_slice（）方法输出如下：
$output =
Array
(
[rows] => Array
(
[0] => Array
(
[id] => 214501
[title] => SRM- 3860(Res-2)
[zip] => SRM-3860(Test_2).zip
)
)
)
我希望/需要的输出是：
$output =
Array
(
[111] => Array
(
[message] => Invalid it is
[type] => error
[headers] => Array
(
[0] => Array
(
[name] => ID
[property] => id
)
[1] => Array
(
[name] => Title
[property] => title
)
[2] => Array
(
[name] => Zip
[property] => zip
)
)
[rows] => Array
(
[0] => Array
(
[id] => abcd
[title] => title
[zip] => abcd
)
)
)
)
我怎样才能做到这一点？ 我的array_slice方法有问题吗？
答案 0 :(得分：1)
这个怎么样：
$my_desired_output = [];
foreach ($input as $key => $operation)
{
if($operation['type'] == 'error')
{
$my_desired_output[$key] = $operation;
}
}
