在二维数组中使用搜索记录

我正在尝试做一件事，但我没有抓住要点。有人能建议我吗。。类似下方的二维阵列

$array = Array
([1] => Array
    ([1] => EST_ID
     [2] => EST_CODE
     [3] => EST_EXT
     [4] => EST_NAME
     [5] => INCROP_ADDRESS1
     [6] => INCROP_ADDRESS2
     [7] => INCROP_CITY
     [8] => INCROP_DIST
     [9] => INCROP_STATE
     [10] => INCROP_PIN
     )
 [2] => Array
    ([1] => HRKNL0006923000
     [2] => 6923
     [4] => VAIBHAV CARPETS
     [5] => BHUL-BHULIA CHOWK
     [6] => BODHWA RAM COLONY
     [7] => PANIPAT
     [8] => PANIPAT
     [10] => 132103)
 [3] => Array
    ([1] => HRKNL0004638000
     [2] => 4638
     [4] => GURU TEG BHADUR PUBLIC SCHOOL
     [5] => MODEL TOWN
     [6] => KARNAL
     [7] => KARNAL
     [8] => KARNAL
     [10] => 132001)
)

我必须从$array 中搜索2或3的数组关键字
