improving my code: array of references

[Pierre Mariani]

Hello everyone,

I have a 'modify_variable' function that, well, modifies a variable.

I want to run it on several variables.

I have the following code that:
- builds an array of references on the variables,
- calls the function on the content of the reference,
- set the content of the reference to the result of the function.


# $var1, $var2 and $var3 are set previously

for     (       \$var1,
                \$var2,
                \$var3,
        ) 

{
        ${$_} = modify_variable ( ${$_} );
}

Questions:
- How do I improve my array definition?
- How to I call the modify_variable function in a more elegant way? 

Thanks in advance.
