3.0 PhpConfig rework to complain php5.4 array syntax

var_export return arrays in old format like:

~~~
array (
  0 => 1,
  1 => 2,
  2 => 
  array (
    0 => 'a',
    1 => 'b',
    2 => 'c',
  ),
)
~~~

I think php5.4 format more readable in config files
~~~
[
  0 => 1,
  1 => 2,
  2 => 
  [
    0 => 'a',
    1 => 'b',
    2 => 'c',
  ],
]
~~~
Any ideas?
Methods need to be camelBacked.
