you cannot dictate "names" of arguments outside function.

function ($foo, $bar) ... 

here first positional argument assigned variable $foo, second 1 $bar.

function () {     $args = func_get_args();     ... } 

here positionally passed arguments assigned array $args. values have no "name", because "names" aren't passed.

if pass array key-value pairs, do, argument array contains key-value pairs. array still plays according above rules.

maybe you're looking extract(), or maybe want not how works.
