多维数组合并问题

Question

如何将如下数组张换乘长度为4的一维数组

array(2) {
  [0]=>
  array(9) {
    ["user_name"]=>
    string(9) "abc"
    ["user_id"]=>
    string(18) "115841106995855361"
    ["product"]=>
    string(12) "kd"
    ["apply_no"]=>
    string(17) "KD026201710310141"
    ["overdue_total"]=>
    int(1086709)
    ["credit_date"]=>
    NULL
    ["household_address"]=>
    string(0) ""
    ["home_address"]=>
    string(57) "云南省|昆明市|昆明市沿河路金碧苑8单元101"
    ["company_address"]=>
    string(0) ""
  }
  [1]=>
  array(3) {
    [0]=>
    array(9) {
      ["user_name"]=>
      string(9) "bbb"
      ["user_id"]=>
      string(18) "115920576776257539"
      ["product"]=>
      string(12) "kd"
      ["apply_no"]=>
      string(17) "KD012201711010042"
      ["overdue_total"]=>
      int(322821)
      ["credit_date"]=>
      NULL
      ["household_address"]=>
      string(0) ""
      ["home_address"]=>
      string(50) "辽宁省|大连市|沙河口区中山路716号203"
      ["company_address"]=>
      string(0) ""
    }
    [1]=>
    array(9) {
      ["user_name"]=>
      string(9) "bbb"
      ["user_id"]=>
      string(18) "115920576776257539"
      ["product"]=>
      string(12) "yd"
      ["apply_no"]=>
      string(18) "XJD012201711010034"
      ["overdue_total"]=>
      int(87746)
      ["credit_date"]=>
      NULL
      ["household_address"]=>
      string(0) ""
      ["home_address"]=>
      string(50) "辽宁省|大连市|沙河口区中山路716号203"
      ["company_address"]=>
      string(0) ""
    }
    [2]=>
    array(9) {
      ["user_name"]=>
      string(9) "bbb"
      ["user_id"]=>
      string(18) "115920576776257539"
      ["product"]=>
      string(9) "sfq"
      ["apply_no"]=>
      string(18) "XJD012201711010034"
      ["overdue_total"]=>
      int(87746)
      ["credit_date"]=>
      NULL
      ["household_address"]=>
      string(0) ""
      ["home_address"]=>
      string(50) "辽宁省|大连市|沙河口区中山路716号203"
      ["company_address"]=>
      string(0) ""
    }
  }
}

转换成如下:

array(2) {
  [0]=>
  array(9) {
    ["user_name"]=>
    string(9) "abc"
    ["user_id"]=>
    string(18) "115841106995855361"
    ["product"]=>
    string(12) "kd"
    ["apply_no"]=>
    string(17) "KD026201710310141"
    ["overdue_total"]=>
    int(1086709)
    ["credit_date"]=>
    NULL
    ["household_address"]=>
    string(0) ""
    ["home_address"]=>
    string(57) "云南省|昆明市|昆明市沿河路金碧苑8单元101"
    ["company_address"]=>
    string(0) ""
  }
  [1]=>
    array(9) {
      ["user_name"]=>
      string(9) "bbb"
      ["user_id"]=>
      string(18) "115920576776257539"
      ["product"]=>
      string(12) "kd"
      ["apply_no"]=>
      string(17) "KD012201711010042"
      ["overdue_total"]=>
      int(322821)
      ["credit_date"]=>
      NULL
      ["household_address"]=>
      string(0) ""
      ["home_address"]=>
      string(50) "辽宁省|大连市|沙河口区中山路716号203"
      ["company_address"]=>
      string(0) ""
    }
    [2]=>
    array(9) {
      ["user_name"]=>
      string(9) "bbb"
      ["user_id"]=>
      string(18) "115920576776257539"
      ["product"]=>
      string(12) "yd"

      int(87746)
      ["credit_date"]=>
      NULL

      string(0) ""
      ["home_address"]=>
      string(50) "辽宁省|大连市|沙河口区中山路716号203"
      ["company_address"]=>
      string(0) ""
    }
    [3]=>
    array(9) {
      ["user_name"]=>
      string(9) "bbb"
      ["user_id"]=>
      string(18) "115920576776257539"

}

Answer 1

$newArr = []; foreach ($res as $key => $value) { if (array_keys($value) == range(0, count($value) - 1)) { $newArr = array_merge(array_values($value),$newArr); }else{ $newArr[]= $value; } } print_r($newArr);
