Bug description: FILTER_VALIDATE_EMAIL incorrectly marks an address as valid
if it contains =
Description:
------------
The filter_var function, when used with FILTER_VALIDATE_EMAIL marks an
email address with an = in it as invalid.
According to RFCs 822, 2822 and 5322, = is a valid component to the
local-part of an e-mail address.
Reproduce code:
---------------
<?php
$email_address = "test=m...@example.com";
var_dump(filter_var($email_address, FILTER_VALIDATE_EMAIL));
$email_address = "test-m...@example.com";
var_dump(filter_var($email_address, FILTER_VALIDATE_EMAIL));
$email_address = "test+m...@example.com";
var_dump(filter_var($email_address, FILTER_VALIDATE_EMAIL));
?>
Expected result:
----------------
string(21) "test-m...@example.com"
string(21) "test-m...@example.com"
string(21) "test+m...@example.com"
Actual result:
--------------
bool(false)
string(21) "test+m...@example.com"
string(21) "test+m...@example.com"
