New Comment:
Multiple consecutive periods in normal email addresses really is invalid. The
fact
that Gmail supports it does not make it valid.
Both RFC 5321 (SMTP) and 5322 (Internet Message Format) paraphrased say:
addr-spec = dot-atom "@" domain
dot-atom = atext+ ("." atext+)*
atext = letters | digits | some symbols not including "."

Description:
------------
Email with multiple period in a row fail validation when they are working
email.
With gmail you can add periods into any email address and it will still
deliver.
I use this to filter out messages. [email protected] is the same as
[email protected] or [email protected] or [email protected].
With one period or if there is a letter or number between period the
FILTER_VALIDATE_EMAIL works just fine but if more than one period it fails.
Test script:
---------------
<?php
$email_a = '[email protected]';
$email_b = '[email protected]';
$email_c = '[email protected]';
if (filter_var($email_a, FILTER_VALIDATE_EMAIL)) {
echo "This ($email_a) email address is considered valid.\n";
} else {
echo "$email_a failed\n";
}
if (filter_var($email_b, FILTER_VALIDATE_EMAIL)) {
echo "This ($email_b) email address is considered valid.\n";
} else {
echo "$email_b failed\n";
}
if (filter_var($email_c, FILTER_VALIDATE_EMAIL)) {
echo "This ($email_c) email address is considered valid.\n";
} else {
echo "$email_c failed\n";
}
Expected result:
----------------
This ([email protected]) email address is considered valid.
This ([email protected]) email address is considered valid.
This ([email protected]) email address is considered valid.
Actual result:
--------------
This ([email protected]) email address is considered valid.
This ([email protected]) email address is considered valid.
[email protected] failed
