以递归方式获取对象属性和值(getting object properties and values recursivly)

以递归方式获取对象属性和值(getting object properties and values recursivly)

所以我有一个对象：

$user->name->first = "Bob"; $user->name->last = "Smith"; $user->address->street = "1234 anywhere st."; $user->address->city = "Chicago"; $user->address->state = "Texas";

如何在不知道“名称，地址”属性的情况下迭代这个对象？

我希望能够做到

foreach ($user as $key -> $value) {}

现在我可以这样做：

foreach ($user as $key -> $value) { foreach ($value as $k => $v) { echo $k . "," . $v . "\n"; } }

我得到一个很好的小清单

first,Bob last,Smith street,1234 anywhere st. city,Chicago state,Texas

但是如何获取要打印的属性名称或地址？

即

name,first,Bob name,last,Smith address,street,1234 anywhere st. address,city,Chicago address,state,Texas

so i have an object:

$user->name->first = "Bob"; $user->name->last = "Smith"; $user->address->street = "1234 anywhere st."; $user->address->city = "Chicago"; $user->address->state = "Texas";

how can i iterate through this object without knowing the "name,address" property?

I want to be able to do

foreach ($user as $key -> $value) {}

now i can do this:

foreach ($user as $key -> $value) { foreach ($value as $k => $v) { echo $k . "," . $v . "\n"; } }

and i get a nice little list of

first,Bob last,Smith street,1234 anywhere st. city,Chicago state,Texas

but how can i get the property name or address to print?

i.e.

name,first,Bob name,last,Smith address,street,1234 anywhere st. address,city,Chicago address,state,Texas

最满意答案

你想要的值是来自第一个foreach循环的$key 。

foreach ($user as $key => $value) { foreach ($value as $k => $v) { echo "$key,$k,$v\n"; } }

The value you want is in $key already from the first foreach loop.

foreach ($user as $key => $value) { foreach ($value as $k => $v) { echo "$key,$k,$v\n"; } }
