Description:
------------
Is there some reason why a $_GET or other server variable cannot be included directly within a function declaration, as its default value?

If using the reproduce code below I get a parse error:

Parse error: parse error, unexpected T_VARIABLE in [scriptaddress] on line [linenumber]


Reproduce code:
---------------
function queryParameters ($queryString = $_GET['QUERY_STRING'])
{
	# Do something with $queryString
}

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions. 

Thank you for your interest in PHP.

It has nothing to do with it being a superglobal or not. You just can ONLY use constants as default values.

Is this a deliberate restriction? It seems a perfectly reasonable thing to want to do. Perhaps this is a feature request then..

Yes, this is deliberate because it's hard to chose from which scope to pick the variables from (calling, or called). Don't bother with a feature request, it won't be changed anyway.
