我有以下两个数组,带键 2016 2017

array(2) {

    string(19) "2017-06-21 10:25:49"
    [7]=>
    string(19) "2017-06-21 10:25:49"
    ["ip"]=>
    string(9) "127.0.0.1"
    [8]=>
    string(9) "127.0.0.1"

    ["date_only"]=>
    string(4) "2017"
    [14]=>
    string(4) "2017"
  }
}

2016 和但是我得到了一个有3个键的数组,它并没有用相同的键覆盖数组。

$final = array_merge($results,$results_from_db);

array(3) {
  [0]=>
  array(11) {
    ["id"]=>
    string(1) "0"
    [0]=>
    string(1) "0"

    string(0) ""
    ["action"]=>
    string(11) "banner view"
    [4]=>
    string(11) "banner view"
    ["entry_details"]=>
    string(0) ""
    ["created"]=>
    string(4) "2016"

    int(0)

带有数字键的输入数组中的值将用结果数组中从零开始的递增键重新编号。

http://php.net/manual/en/function.array-merge.php

mickmackusa Tom Green 7 年前

array_replace() 将用第二个子阵列覆盖第一个子阵列:

var_export(array_replace($a,$b));

+ ksort()

$overwrite=$b+$a;
ksort($overwrite);
var_export($overwrite);

demo link 您可以在其中使用两个数组变量上的函数。

array_merge() 和 array_merge_recursive() 将产生3个子阵列。

即使您将键转换为字符串,如 '2017' array\u merge() 仍然将它们视为数字,并且您将得到3个子阵列。

如果您尽可能在每个键前加前缀 # ,则您可以使用 array\u merge() 按预期。尝试使用 #[year]
