我有两个不同的数组
第一个阵列：
Array
(
[0] => stdClass Object
(
[course_id] => 21
[session_id] => 17
[course_name] => Session 1 Course 1
[course_description] => Session 1 Course 1
[course_days] => 2
[current_rate] => 1000
[old_rate] =>
[primary_tutor_id] => 18
[secondary_tutor_id] => 25
[additional_time] =>
[location] =>
[course_active] => 1
)
[1] => stdClass Object
(
[course_id] => 22
[session_id] => 17
[course_name] => Session 1 Course 2
[course_description] => Session 1 Course 2
[course_days] => 3
[current_rate] => 1000
[old_rate] =>
[primary_tutor_id] => 24
[secondary_tutor_id] => 25
[additional_time] =>
[location] =>
[course_active] => 1
)
[2] => stdClass Object
(
[course_id] => 23
[session_id] => 17
[course_name] => Session 1 Course 3
[course_description] => Session 1 Course 3
[course_days] => 5
[current_rate] => 2000
[old_rate] =>
[primary_tutor_id] => 26
[secondary_tutor_id] => 27
[additional_time] =>
[location] =>
[course_active] => 1
)
[3] => stdClass Object
(
[course_id] => 26
[session_id] => 19
[course_name] => Session 3 Course 2
[course_description] => Session 3 Course 2
[course_days] => 2
[current_rate] => 400
[old_rate] =>
[primary_tutor_id] => 29
[secondary_tutor_id] => 29
[additional_time] =>
[location] =>
[course_active] => 1
)
[4] => stdClass Object
(
[course_id] => 27
[session_id] => 19
[course_name] => Session 3 Course 3
[course_description] => Session 3 Course 3
[course_days] => 1
[current_rate] => 200
[old_rate] =>
[primary_tutor_id] => 26
[secondary_tutor_id] =>
[additional_time] =>
[location] =>
[course_active] => 1
)
)
第二阵列：
Array
(
[0] => stdClass Object
(
[discount_id] => 104
[session_id] => 17
[no_course] => 3
[discount] => 20
)
[1] => stdClass Object
(
[discount_id] => 106
[session_id] => 19
[no_course] => 2
[discount] => 20
)
)
我正在尝试将第二个数组的所有键和值组合到第一个数组中，如下面的示例
Array
(
[0] => stdClass Object
(
[course_id] => 21
[session_id] => 17
[course_name] => Session 1 Course 1
[course_description] => Session 1 Course 1
[course_days] => 2
[current_rate] => 1000
[old_rate] =>
[primary_tutor_id] => 18
[secondary_tutor_id] => 25
[additional_time] =>
[location] =>
[course_active] => 1
[discount_id] => 104
[session_id] => 17
[no_course] => 3
[discount] => 20
)
)
我已经尝试过以下代码和许多其他代码，但我无法获得完美的解决方案。在这两个数组中，如果两个[session_id]与需要数组合并相同，则会有一个例外，因为它是没有合并的数组：
$main=array();
foreach ($courses as $key => $val) {
foreach ($session_discount as $se) {
if ($se->session_id == $val->session_id)
$main[$key] = $val;
array_push($main[$key], $session_discount[0]);
}
}
需要帮助..！在此先感谢。
