Bug description:  is_numeric with currency values

Description:
------------
The function is_numeric() fails when the input is a value with thousand
and decimal separators.

For example: 4.000,56 or 4,000.56.

We had a short discussion about this in #php irc channel and found out the
following:

"4,000.56" = is USA notation
"4.000,56" = is European notation

They are perfectly valid numeric values, used in currency/weight/cubic
centimeters/etc.


Suggested solutions:

1) Both notations should be accepted.

2) Only one notation should be accepted and PHP will decide which one,
based on the Locale of the server/setup.

Any other suggestion is welcome.


Reproduce code:
---------------
Reproduction code:

<?php

$dolars = "4,000.56";
$euros = "4.000,56";

$rc = is_numeric($dolars);
var_dump($rc);

$rc = is_numeric($euros);
var_dump($rc);

?>

Expected result:
----------------
is_numeric should have returned TRUE in both cases.


Actual result:
--------------
is_numeric returns false for both.
