How to evaluate the value of a variable ?

How to evaluate the value of a variable ?
For example:

a=var
$a=value !!!error happens!!!

I want to evaluate var=value, how to realize it?
Thanks!

---------- Post updated at 03:37 AM ---------- Previous update was at 02:22 AM ----------

I am using linux bash.
Code:
a=var
$a=value !!!error happens!!!

I want the following result:
Code:
$echo $a
var
$echo $var
value

So I want the value of $a to be a variable, and it can be valued.
