搜索特定值的多维数组 [英] Search a multi-dimensional array for certain values

问题描述

我有以下格式的多维数组：

I have a multi-dimensional array in the following format:

[0] = (
    'id' => '1',
    'type' => 'fish', 
    'owner' => 'bob',
)

[1] = (
    'id' => '2',
    'type' => 'cat', 
    'owner' => 'mary',
)

[2] = (
    'id' => '3',
    'type' => 'dog', 
    'owner' => 'larry',
)

[3] = (
    'id' => '2',
    'type' => 'cat', 
    'owner' => 'fred',
)

我想搜索的价值，他们返回一个包含匹配阵列的所有按键，看起来像这样对类型搜索=猫数组：

I would like to search for a value, and they return an array that contains all keys from matching arrays and looks like this on a search for type=cat:

[0] = (
    'id' => '2',
    'type' => 'cat', 
    'owner' => 'mary',
)

[1] = (
    'id' => '2',
    'type' => 'cat', 
    'owner' => 'fred',
)

我知道我试图治疗阵列作为数据库，但在这种情况下，它不需要一旦程序结束要存储动态数据。

I know I'm trying to treat the array as a database, but in this case it's dynamic data that doesn't need to be stored once the program ends.

任何意见？

推荐答案

遍历数组：

function loopAndFind($array, $index, $search){
         $returnArray = array();
         foreach($array as $k=>$v){
               if($v[$index] == $search){   
                    $returnArray[] = $v;
               }
         }
         return $returnArray;
}

//use it:
$newArray = loopAndFind($oldArray, 'type', 'cat');
