Class array property by reference [duplicate]

Question

If I have the following variable in a class

protected $address

and in a function test, I do

$testAddress = $this->address;

and then

$testAddress['state'] = 'KO';

Does that change the state for $this->address ... meaning any function that uses $this->address will have the modified state?

No it does not. $this->address will remain the same unless you pass by reference — Sabari

Would have been pretty easy to write that code and see what happens. — Jessica

The fact that you need it means that you have fundamental issues with design — zerkms

It will only change the state or value of $testAddress but not $this->address.

As per the given code, nothing yet has been set as value on $address
