Hello,
I have the following situation:

$list[] is an array of MyElement objects.

MyElement has two members: MyElement->member1; MyElement->member2;

What I want is to get the following:

$newlist[] so that:

$newlist[0]=$list[0]->member2;
$newlist[1]=$list[1]->member2;
$newlist[2]=$list[2]->member2;
....

I need to do this using A SINGLE LINE OF CODE.
Is it possible? How to do this?

I tried with:

array_walk($list,create_function('$a,$b,$result','$result[] =
$a->member2;'), &$result);

but I get the following error:

Warning: Call-time pass-by-reference has been deprecated - argument
passed by value; If you would like to pass it by reference, modify the
declaration of array_walk(). If you would like to enable call-time
pass-by-reference, you can set allow_call_time_pass_reference to true in
your INI file. However, future versions may not support this any longer.

Thank you
Regards
