bash variable expansion as parameter [duplicate]

I have a command (zip, but nevermind) in which I have a parameter like

cmd /foo/bar/{*.php,*.css,images/}

I would like to put it in a variable to pass it to the command as :

VAR=/foo/bar/{*.php,*.css,images/}
cmd ${VAR}

But, whatever I try, it never expand as I want. I tried with or without quotes, but not better.

EDIT:

(No answer possible because closed) I hadn't been able to find it, but the solution did exist:

VAR=(/foo/bar/{*.php,*.css,images/})
cmd ${VAR[@]}
