从php中的单个多维数组中获取常用值

Question

我有一个名为$ array的数组，它是多维数组。它包含品牌名称，产品子类别（键不是静态的，它们可以是任何东西，甚至键的数量都不固定）。我想从阵列中的所有的共同价值观

当前数组：

$array = array 
(
    [brandname] => Array 
     (
      [0] => Array 
       (
        [0] => sony_brandname 
        [1] => touch screen_type 
        [3] => 2.8_size 
        [4] => gsm + gsm_sim_support 
        [5] => 2_primary_camera 
        [6] => 64 mb_internal_memory 
        [7] => 32_expandable_memory 
        [8] => 1200_standard_battery_type 
        [9] => 3_size 
       [10] => 1000_standard_battery_type 
       [11] => touch and type_type   
       ) 

     ) 

    [productsubcategory] => Array 
     (
      [1] => Array 
       (
        [0] => karbonn_brandname 
        [1] => touch and type_type 
        [2] => micromax_brandname 
        [3] => 2.8_size 
        [4] => gsm_sim_support 
        [5] => 3.15_primary_camera 
        [6] => 52 mb_internal_memory 
        [7] => 8_expandable_memory 
        [8] => 1000_standard_battery_type 
        [9] => nokia_brandname 
        [10] => symbian s40_os_clean 
        [11] => 5_primary_camera 
        [12] => 128 mb_ram 
        [13] => 256 mb_internal_memory 
        [14] => 32_expandable_memory 
        [15] => 1110_standard_battery_type 
        [16] => gsm + gsm_sim_support 
        [17] => 2_primary_camera 
        [18] => 32 mb_ram 
        [19] => 10 mb_internal_memory 
        [20] => no_expandable_memory 
        [21] => 1020_standard_battery_type 
        [22] => 680 mhz_processor 
        [23] => 64 mb_ram 
        [24] => 128 mb_internal_memory 
        [25] => 860_standard_battery_type 
        [26] => blackberry_brandname 
        [27] => 2.45_size 
        [28] => 1 ghz_processor 
       ) 

     ) 

); 

期望的数组：

$array = array 
(
    [0] => sony_brandname 
    [1] => touch and type_type 
    [2] => 2.8_size 
    [8] => 1000_standard_battery_type 
    [16] => gsm + gsm_sim_support 
    [17] => 2_primary_camera 
) 

Answer 1

使用array_intersect()：

$result = array_intersect($array["brandname"][0], $array["productsubcategory"][1]); 
print_r($result);
