我如何从这个数组得到[USER_ID]

阵列（      [2] =＆GT; cbpaidSubscription对象        （            [replaces_plan] =＆GT;        [replaces_subscription] =＆GT;        [subscription_date] =＆GT; 2009-07-14 12点45分52秒        [last_renewed_date] =＆GT; 2009-07-14 12点45分52秒        [EXPIRY_DATE] =＆GT; 2010-07-14 12点45分52秒        [autorenew_type] =＆GT; 2        [autorecurring_type] =＆GT; 2        [regular_recurrings_total] =＆GT; 0        [regular_recurrings_used] =＆GT; 1        [previous_expiry_date] =＆GT;        [previous_status] =＆GT; - [R        [previous_recurrings_used] =＆GT; 0        [ip_addresses] =＆GT; 127.0.0.1        [ID] =＆GT; 2        [现状] =＆GT;一个        [USER_ID] =＆GT; 71        [plan_id的数据类型] =＆GT; 1        [parent_plan] =＆GT; 0        [parent_subscription] =＆GT; 0        [积分] =＆GT;        [_plan] =＆GT; cbpaidProductusersubscription对象            （

解决方案

如果你能保证该数组只有一个项目，你知道密钥，然后用乔纳森·桑普森的解决方案去了。否则，如果你有一个这样可以循环的几个项目上并提取用户标识的每一个。

的foreach（$数组作为$项目）{    $用户id = $本期特价货品＆GT; USER_ID;    //为这个项目做的用户id的东西}

how can i get [user_id] from this array?

Array ( [2] => cbpaidSubscription Object ( [replaces_plan] => [replaces_subscription] => [subscription_date] => 2009-07-14 12:45:52 [last_renewed_date] => 2009-07-14 12:45:52 [expiry_date] => 2010-07-14 12:45:52 [autorenew_type] => 2 [autorecurring_type] => 2 [regular_recurrings_total] => 0 [regular_recurrings_used] => 1 [previous_expiry_date] => [previous_status] => R [previous_recurrings_used] => 0 [ip_addresses] => 127.0.0.1 [id] => 2 [status] => A [user_id] => 71 [plan_id] => 1 [parent_plan] => 0 [parent_subscription] => 0 [integrations] => [_plan] => cbpaidProductusersubscription Object (

解决方案

If you can guarantee that the array only has one item and you know the key, then go with Jonathan Sampson's solution. Otherwise if you have a few items you can loop over it like this and extract the userid for each one.

foreach ($array as $item) { $userId = $item->user_id; //do something with the userId for this item }
