Assigning object variables to array in PHP

Question

I would like to pre-define my object variables into an array. After that, I need to access one element at a time from that array and assign a value to it. Like so:

$obj = new StdClass();
$arr = ["$obj->item1"];
$arr[0] = "apple";
print_r($obj); // expecting to see $obj->item1 = apple

I know I'm doing something wrong above, but could not figure out what.

you’re overwriting $arr[0], instead of assigning the property of $obj. What’s probably messing you up is that objects pass by reference; but arrays by value. — Tim Morton

If you assign just the object to $arr[0], then you might possibly be able to set $obj->item1 somewhere else in the code, and then reference $arr[0]->item1. — Tim Morton

Solved. Thanks to the hint from Tim Burton

$arr = [&$obj->item1];
