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" ["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) "" } [3]=> 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) "" } }

$newArr = []; 
foreach ($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);
