PHP - How to concatenation 2 php var for create a new php var?

Question

I want to concatenation $test with $i for create a new php var.

like this but not work, how can i do ?

<?PHP
$i = "5";
$test_$i = "WELCOME";
echo $test_5;
?>

Why do you want to do that? Most likely there is a much better solution. Could you explain your usecase please? — PeeHaa, Nov 22 '16 at 14:41
