Question

我有一个PHP多维数组

我想使用多键和配对在此数组中搜索

当前，我正在使用该功能

function search_revisions($dataArray, $search_value, $key_to_search, $other_matching_value = null, $other_matching_key = null) {
    // This function will search the revisions for a certain value
    // related to the associative key you are looking for.
    $keys = array();
    foreach ($dataArray as $key => $cur_value) {
        if ($cur_value[$key_to_search] == $search_value) {
            if (isset($other_matching_key) && isset($other_matching_value)) {
                if ($cur_value[$other_matching_key] == $other_matching_value) {
                    $keys[] = $key;
                }
            } else {
                // I must keep in mind that some searches may have multiple
                // matches and others would not, so leave it open with no continues.
                $keys[] = $key;
            }
        }
    }
    return $keys;
}

从@amurrell借来的答案在这里PHP multidimensional array search by value

此函数对于两个键值对工作良好，并返回数组的索引，但是我想按多个键和键对和值对中的4和5进行搜索

我想要一个类似

的函数

search_by_value($array,$first_key,$first_value,$second_key=null,$second_value=null,$third_key=null,$third_value=null,$fourth_key=null,$fourth_value=null);

或更像

search_by_value(array('$key',$value));

并且输出应该是与键值匹配的索引

    Array
(
    [0] => 5
)

或者如果它与多个值匹配

    Array
(
    [0] => Array
        (
            [0] => 4
            [1] => 5
            [2] => 6
        )

)

您可以创建一个关联数组，并测试该关联数组中的所有键/值是否都存在于主数组中

function search_by_values($array,$searchValues) {
$keys = [];
foreach($array as $key => $value) {//loop each array value
      $isInArray = false;//
      foreach($searchValues as $searchKey => $searchValue) {//loop the search array
         if($value[$searchKey] != $searchValue) {//test if the key value pair is in the array
              $isInArray = false;//the value of the key doesn't match 
               break;//we exit the inner loop with  $isInArray = false
         } else {
            $isInArray = true;//if all the values are in the array we will exit with  $isInArray = true;
         }
      }
      if($isInArray) {
        $keys[] = $key;
      }
}
return $keys;

}

对于“活着死”评论，请使用数组作为条件，其中条件是键中要检查的键，值是要在这些键中搜索的值。

首先定义将1个元素检查为的函数：

function checkElemet($element, $conditions) {
    foreach($conditions as $k => $v) {
        if (isset($element[$k]) && $element[$k] != $v)
            return false; // if both set and not equal don't need keep checking
    }
    return true;
}

然后在数组上循环并检查：

function search_by_value($array, $conditions) {
    foreach($array as $k => $v)
        if (checkElemet($v, $conditions)) $res[] = $k;
    return $res;
}
