It depends on context... where do u want to declare this variables ? and
where do you want to use it ?
Understand that when you type : ${$y.'_'.$i}
It's just a replacement.
If $y = 'test' and $i = '0', it's exactly like if you had
${'test'.'_'.'0'}, or ${'test_0'} or $test_0...
Is your 'global' call in a function that needs previously declared
variables ?
To help you, I need to understand what you wanna do and what you need ;)
