Question

我在codeigniter-php中这样做：我有这样的输出：

var_dump($x);
    array
          0 => string 'Start Date :' (length=12)
          1 => string '1-Aug-15' (length=8)
        array
          0 => string 'End Date :' (length=10)
          1 => string '19-Aug-15' (length=9)
        array
          0 => string 'Txn Date' (length=8)
          1 => string 'Value Date' (length=10)
          2 => string 'Description' (length=11)
          3 => string 'Ref No./Cheque No.' (length=18)
          4 => string 'Branch Code' (length=11)
          5 => string 'Debit' (length=5)
          6 => string 'Credit' (length=6)
          7 => string 'Balance' (length=7)

但我想要包含6个子阵列的数组：我希望获得这个数组：我有很多包含6个子数组和2个子数组的数组，但是我想要6个子数组同时使用array.please help：

array
              0 => string 'Txn Date' (length=8)
              1 => string 'Value Date' (length=10)
              2 => string 'Description' (length=11)
              3 => string 'Ref No./Cheque No.' (length=18)
              4 => string 'Branch Code' (length=11)
              5 => string 'Debit' (length=5)
              6 => string 'Credit' (length=6)

Answer 1

function getSubArray(Array $arr, $l = 6) {
    foreach($arr as $subArr) {
        if (is_array($subArr) && count($subArr) === $l) {
            return $subArr;
        }
    }
    return null;
}

$result = getSubArray($x);
