No. But there are default arguments, and variable-length argument lists
(PHP 4+).
See http://www.php.net/manual/functions.arguments.php.

No. But there are functions like call_user_func(), which make them
somewhat redundant.
See http://www.php.net/call_user_func.

How about:

function foo($arg)
{
echo "foo $arg foo\n";
}

function bar()
{
return "barfoo";
}

foo(bar());
