Getting Data from an Array

Question

Unfortunately my last post was closed, so I try it again: I have an Array. I think it is multidimensional and I want to read out two values from it.

This is a piece of it:

d" ["rec_surname"]=> string(46) "-------------------bvvcb----------------------" ["rec_name"]=> string(52) "---------------------------vcbxcvb------------------" } } }

I want to read out the value rec_surname. I tried it in that way:

$message["params"]["invite"]["data"]["rec_surname"] ; but got an error Message.

Where is the mistake?
