如何将两个数组连接到一个数组？在日期位置 0 和 1 都在循环中连接，我的数组代码在下面。Array( [Apr-2019] => Array ( [0] => Array ( [DateUser] => Apr-2019 [withdarw_amount] => 4.00 ) [1] => Array ( [current_deposit_amount] => 1.00 [current_deposit_table_refer] => 0.00 [current_deposit_user_refer] => 0.10 [DateUser] => Apr-2019 ) )) 像我的输出：[Apr-2019] => Array ( [DateUser] => Apr-2019 [withdarw_amount] => 4.00 [current_deposit_amount] => 1.00 [current_deposit_table_refer] => 0.00 [current_deposit_user_refer] => 0.10 [DateUser] => Apr-2019 )我曾尝试使用此代码，$data = array_merge($withdrow_amount,$data_casback,$cashbonus_data,$data_discount,$CurrentDeposit);$months = array();foreach($data as $date) { $month = substr($date['DateUser'], 0, 8); $months[$month][] = $date;}echo '<pre>'; print_r($months); die;

您可以迭代您的数组，使用array_mergesplat运算符...来展平内部数组。请注意，数组中不能有两个DateUser键，因此将删除一个；假设它们具有与您的数据相同的值，这不会成为问题：
$array = array (
'Apr-2019' =>
array (
0 =>
array (
'DateUser' => 'Apr-2019',
'withdarw_amount' => 4.00
),
1 =>
array (
'current_deposit_amount' => 1.00,
'current_deposit_table_refer' => 0.00,
'current_deposit_user_refer' => 0.10,
'DateUser' => 'Apr-2019'
),
),
'Jun-2019' =>
array (
0 =>
array (
'DateUser' => 'Jun-2019',
'withdarw_amount' => 334.00
),
)
);
foreach ($array as &$arr) {
$arr = array_merge(...$arr);
}
print_r($array);
输出：
Array
(
[Apr-2019] => Array
(
[DateUser] => Apr-2019
[withdarw_amount] => 4
[current_deposit_amount] => 1
[current_deposit_table_refer] => 0
[current_deposit_user_refer] => 0.1
)
[Jun-2019] => Array
(
[DateUser] => Jun-2019
[withdarw_amount] => 334
)
)

您也可以使用简单的循环来做到这一点 -
$new = [];
foreach ($array as $key =>$a) {
$new[$key] = []; // Define with key
foreach ($a as $v) {
$new[$key] += $v; // Concat
}
}
