How to Reference the Property of an Object that Is A Property Of an Object

[danallen]

Hi, sometimes simple things are hard.  I asked at the pub down the street, but no one had a clue.

 

How do we reference the property [sess_expiration] in the object below?  Seems like it should be possible to use

$this->config->config->sess_expiration

Array(

    [config] => Config Object        (            [config] => Array                (                    [sess_cookie_name] => weird_session                    [sess_expiration] => 2592000                )        )

)

 

This does the job, but this is stupid-looking:

$value_i_need=get_object_vars(get_object_vars($this)['config'])['config']['sess_expiration']

 

If you could fill me in on how to deal with this, I would really appreciate it.

 

Thank you.

Looks like you did a

print_r(get_object_vars($this))

Right?

 

1. The thing you printed is an array, because that's what get_object_vars does. But $this is an object.

2. "config" is the thing inside it.

3. It is an object (a Config object).

4. "config" is (again) the next thing inside it.

5. It is an array.

6. "sess_expiration" is one of the values you want.

 

Objects use -> and arrays use [].

$this->config->config["sess_expiration"]

It's been awhile since posting this, but I still appreciate the response. Usually, I am working with arrays. I have had occasion to catch up to a degree on php objects, how and why they are used, read some discussions of trade-offs, and after all that, I would have to say, your explanation is exactly perfect from my perspective, so thank you.
