exploding a variable with [] can this be done?

[sgtpepper]

I am passing a variable from a form to my query. In my original form I had the variable specified as

variable[]

All works fine...except now I am trying to make a more dynamic form with javascript. The java does not like the variable to use [] (this breaks the java code).

I am wondering if I can explode the variable somehow before it gets the the query...something like

$variable = variable[]

So in my form variable gets passed the the query script....before the query something than takes the variable and creates variable[].

Is this possible?
