Description:
------------
In PHP6, extract() function doesnot prefix the string with default
character ("_") when no prefix is provided in argument ,as it does in
PHP5.
According to php5 do***entation, output for testcase with php5 is
correct. i.e when no prefix is provided, default prefix is "_"
(underscore character). Hence while printing the variable _size in php5
, gives correct output ("medium").

Whereas in php6 it gives a warning and notices and refuses to recognize
the other variables (color, shape) as well as expected prefixed variable
(_size).

Reproduce code:
---------------
<?php
$size = "large";
$var_array = array("color" => "blue",
"size" => "medium",
"shape" => "sphere");
extract($var_array, EXTR_PREFIX_SAME, "");
echo "$color, $size, $shape, $_size\n";
?>

Expected result:
----------------
blue, large, sphere, medium

Actual result:
--------------
PHP Warning: extract(): prefix is not a valid identifier in
/home/nikhil/php/tmp.php on line 7
PHP Notice: Undefined variable: color in /home/nikhil/php/tmp.php on
line 9
PHP Notice: Undefined variable: shape in /home/nikhil/php/tmp.php on
line 9
PHP Notice: Undefined variable: _size in /home/nikhil/php/tmp.php on
line 9
