When development time matters, all that others can help is a goal. My PHP app is now parameterized & configured with an include file that contains an array in the form:

```
$config = array(
   'company'            => 'BMC' ,       // the visible company name
   'aplicable_tax'      => .21   ,       // the IVA tax
   'context_arr'        => array(
        'case1'             =>    12,    // the defalul value
        'case2'             =>    13,
        'case3'             =>    14
                           ),
   'EN_welcome_text'       => 'hello',   // do NOT translate on regionalization

   // xx comparation matrix
   'xx_maxref'=> 5,
   'xx_range' => array( 0, 1, 2, 3, 4, 5, 6, 7, 8, 9),
   'xx_comp'  => array( 
    //  V Other V  > I >>   0, 1, 2, 3, 4, 5, 6, 7, 8, 9
        /*  0 */     array( 0, 3, 5, 5, 5, 5, 5, 5, 5, 5),
        /*  1 */     array(-3, 0, 3, 5, 5, 5, 5, 5, 5, 5),
        /*  2 */     array(-5,-3, 0, 3, 5, 5, 5, 5, 5, 5),
        /*  3 */     array(-5,-5,-3, 0, 3, 5, 5, 5, 5, 5),
        /*  4 */     array(-5,-5,-5,-3, 0, 3, 5, 5, 5, 5),
        /*  5 */     array(-5,-5,-5,-5,-3, 0, 3, 5, 5, 5),
        /*  6 */     array(-5,-5,-5,-5,-5,-3, 0, 3, 5, 5),
        /*  7 */     array(-5,-5,-5,-5,-5,-5,-3, 0, 3, 5),
        /*  8 */     array(-5,-5,-5,-5,-5,-5,-5,-3, 0, 3),
        /*  9 */     array(-5,-5,-5,-5,-5,-5,-5,-5,-3, 0),
),

// and so on
// and so on
// and so on
)

```

But this approach is insecure, because any allowed editor can inject PHP code or errors. 

My Questions: 

* Can you suggest a simple and flexible format to give three party a way to parameterize a PHP app?
* Is there a conversion script from that format into a PHP?
