Bug description: extract() function in php6 does not accept the default prefix
character ie. "_"
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 documentation, 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
