我有以下关联数组：
Array
(
[0] => Array
(
[user_id] => 9def02e6337b888d6dbe5617a172c18d
[user_first_name] => Ashutosh
[user_last_name] => Modi
[user_email] => ashutosh.modi@gmail.com
[user_status] => enable
[user_subscription] => lifetime
[user_registered_type] => online
[user_reg_date] => 1325581397
)
[1] => Array
(
[user_id] => a6d22e4cc3f65778a60b359842bcec82
[user_first_name] => Dilip
[user_last_name] => Modi
[user_email] => dm.modi@gmail.com
[user_status] => enable
[user_subscription] => period
[user_registered_type] => online
[user_reg_date] => 1325152066
)
)
它有两把钥匙。现在我有了另一个名为$user_data的数组，它有以下输出：
Array
(
[user_state] => Rajasthan
[user_city] => Jhunjhunu
)
我想把这个键值对添加到上面的数组中。上面的数组只是for循环的第一次迭代，所以上面的值被插入到第一个数组元素中。第二个数组元素将具有一些不同的值。我希望结果如下。你能帮我实现这一点吗？提前谢谢。
Array
(
[0] => Array
(
[user_id] => 9def02e6337b888d6dbe5617a172c18d
[user_first_name] => Ashutosh
[user_last_name] => Modi
[user_email] => ashutosh.modi@gmail.com
[user_status] => enable
[user_subscription] => lifetime
[user_registered_type] => online
[user_reg_date] => 1325581397
[user_state] => Rajasthan
[user_city] => Jhunjhunu
)
[1] => Array
(
[user_id] => a6d22e4cc3f65778a60b359842bcec82
[user_first_name] => Dilip
[user_last_name] => Modi
[user_email] => dm.modi@gmail.com
[user_status] => enable
[user_subscription] => period
[user_registered_type] => online
[user_reg_date] => 1325152066
[user_state] => Tamilnadu
[user_city] => Chennai
)
)
试用array_merge
foreach ($users as &$user)
{
$user = array_merge($user, $user_data);
}
var_dump($users);
<?php
foreach($user_data as $key => $val){
$original_array[$key]['user_state'] = $val['user_state'];
$original_array[$key]['user_city'] = $val['user_city'];
}
假设这两个数组具有相同的密钥
