How can I make a variable's name from another variable AND string?

Say I had the variable $foo which has a value of "bar" and I wanted to make a variable variable from it, but also append the string "123" to it, so that the variable name is $bar123. How would I do this?

I already know that $$foo = "abc123" would make a variable $bar with the value of "abc123", but I don't know how to append a string to this variable name.

Solution

  • I realised the solution was fairly simple:

    $foo = "bar";
$x = $foo . "123"
$$x = "random important variable value"
