Php 过滤多维数组而不影响密钥

我正在做一个定制的PHP项目，我需要得到多维数组的子集

我有一个数组

Array ( [0] => Array ( [0] => 2011 [1] => Allegany [2] => 55.4 ) [1] => Array ( [0] => 2012 [1] => Albany [2] => 325.1 ) [2] => Array ( [0] => 2011 [1] => Bronx [2] => 11 ) [3] => Array ( [0] => 2012 [1] => Bronx [2] => 11 ) ) 排列 ( [0]=>阵列 ( [0] => 2011 [1] =>阿勒加尼 [2] => 55.4 ) [1] =>阵列 ( [0] => 2012 [1] =>奥尔巴尼 [2] => 325.1 ) [2] =>阵列 ( [0] => 2011 [1] =>布朗克斯 [2] => 11 ) [3] =>阵列 ( [0] => 2012 [1] =>布朗克斯 [2] => 11 ) ) 我想返回一个数组，其中存在[0]=>2012，如下所示

Array ( [1] => Array ( [0] => 2012 [1] => Albany [2] => 325.1 ) [3] => Array ( [0] => 2012 [1] => Bronx [2] => 11 ) ) 排列 ( [1] =>阵列 ( [0] => 2012 [1] =>奥尔巴尼 [2] => 325.1 ) [3] =>阵列 ( [0] => 2012 [1] =>布朗克斯 [2] => 11 ) ) 编写此函数是为了允许您根据可自定义条件从数组中选择条目子集

$subset = array_filter(
    $originalArray,
    function($value) {
        return isset($value[0]) && $value[0] == 2012;
    }
);

或更通用的变体：

$searchColumn = 0;
$searchValue = 2012;

$subset = array_filter(
    $originalArray,
    function($value) use ($searchColumn, $searchValue) {
        return isset($value[$searchColumn]) && $value[$searchColumn] == $searchValue;
    }
);

编辑

用于简化在不同列中搜索匹配项的变量

$searchCriteria = [0 => 2012, 2 => 11];

$subset = array_filter(
    $originalArray,
    function($value) use ($searchCriteria) {
        return count($searchCriteria) == count(array_intersect_assoc($value, $searchCriteria));
    }
);

好的，那么您需要检查数组中的所有项，并检查是否有键为0且值为2012的子项。交易是什么？巨大的答案：）顺便说一句，不使用任何函数的逻辑：

foreach（$arr as$key=>$v）if（$v[0]==2012）$out[$key]=v非常感谢。那很好用。但是如果我必须过滤两个元素，比如“[0]=>2012和[2]=>11”，那么您需要修改回调的逻辑
return-isset（$value[0]）&&&$value[0]==2012&&isset（$value[2]）&&$value[2]==11
