如何检索从PHP对象数组中的项？ [英] How do I retrieve an item from an PHP Object Array?

问题描述

我想从这个数组检索数量。

我试过C $ CS一堆$像$ invoice->量，$发票[1] - >量，这$ - > $ invoice->的数量，但他们都不显示

它仍然不会显示在所有，我试图print_r的，这是它给我的数组。

解决方案

好像所有的数据都在私人属性。你不能从外部直接访问它。

阅读类的文档。它应该有一些方法可以调用，如 getQuantity（），即会得到你的数据。这取决于类是如何写的，它是按照正确的方式使用。

I want to retrieve quantities from this array.

  invoice Object
    (
    [data:private] => Array
    (
    [i_status] => pend
    [i_title] => 500 HLCoins , 500 HLCoins x8
    [i_member] => 1
    [i_items] => Array
    (
    [0] => Array
    (
    [act] => new
    [app] => nexus
    [type] => product
    [cost] => 0
    [tax] => 0
    [renew_term] => 0
    [renew_units] =>
    [renew_cost] => 0
    [quantity] => 1
    [physical] =>
    [shipping] => Array
    (
    )
    [weight] => 0
    [itemName] => 500 HLCoins
    [itemID] => 3
    [cfields] => Array
    (
    )
    [extra] =>
    [opt_id] => 0
    [associated] =>
    [assocBought] =>
    [groupRenewals] => 0
    [methods] => Array
    (
    )
    [k] => 0
    [_tax] => 0
    )
    [1] => Array
    (
    [act] => new
    [app] => nexus
    [type] => product
    [cost] => 0
    [tax] => 0
    [renew_term] => 0
    [renew_units] =>
    [renew_cost] => 0
    [quantity] => 8
    [physical] =>
    [shipping] => Array
    (
    )
    [weight] => 0
    [itemName] => 500 HLCoins
    [itemID] => 3
    [cfields] => Array
    (
    )
    [opt_id] => 0
    [groupRenewals] => 0
    [methods] => Array
    (
    )
    [_tax] => 0
    )
    )
    [i_total] => 0
    [i_date] => 1347217384
    [i_return_uri] =>
    [i_paid] => 0
    [i_status_extra] => a:1:{s:4:"type";s:4:"zero";}
    [i_discount] => 0
    [i_temp] =>
    [i_ordersteps] => 0
    [i_noreminder] => 1
    [i_renewal_ids] => Array
    (
    )
    [i_po] =>
    [i_notes] =>
    [i_shipaddress] =>
    [i_id] => 229
    )


        [takeAction] => 1
    )

I've tried a bunch of codes like $invoice->quantity, $invoice[1]->quantity, $this->$invoice->quantity, but none of them seem to display.

It still does not display at all, I tried to print_r and that is the array it gave me.

解决方案

Seems like all the data is in a private property. You cannot access it from outside directly.

Read the documentation for the class. It should have some method you can call, like getQuantity(), that'll get you the data. It depends on how the class was written and how it is supposed to be used.
