PHP: use $_GET in define

I am trying to define a constant like in my code below for being able to easily switch between $_POST and $_GET without the need to change multiple lines.

But I get the following Error:

Parse error: syntax error, unexpected '[', expecting :: (T_PAAMAYIM_NEKUDOTAYIM) in /var/www/public_docs/admin/web_interface/contract.php on line 14

define(DEFAULT_DATA_METHOD, $_GET);   // change to $_POST if post should be used

function getData($Name, $Default = "")
/// Encapsulate data retrieval from $_GET or $_POST
{
 return (isset(DEFAULT_DATA_METHOD[$Name]) ? DEFAULT_DATA_METHOD[$Name] : $Default); <-- Line 14
}

Is what I want to achieve possible? And how?

Solution

  • You can't use define with an array. The documentation is very clear about it:

    value
    The value of the constant; only scalar and null values are allowed. Scalar values are integer, float, string or boolean values.

    You can use an ordinary reference variable:

    $default_data_method =& $_GET;

    Or you could use $_REQUEST, which automatically merges $_POST and $_GET.
