Call-time pass-by-reference for non-object Variables is Deprecated?
We can use word "new" with Call-time pass-by-value for object,but how to use  pass-by-reference in Call-time for non-object Variables like int,string,array?

Reproduce code:
---------------
$a=1;
$b=$a;
$c=&$a;
$a='cc';
tt($c);
echo $b."<BR/>";
echo $c."<BR/>";

echo "pass by value"."<BR/>";
tt(&$c);
echo $b."<BR/>";
echo $c;
function tt($aa){
	$aa="erety";
}

Expected result:
----------------
Deprecated: Call-time pass-by-reference has been deprecated in F:\Programming\Web\php\mykernel\test\arg\fun_ref_time.php on line 11
