Hi D :-)
I was following along.. also felt pleased to be introduced to filter_var ...
and then happened to see this:
http://us3.php.net/manual/en/function.filter-var.php
the user-contributed note, headed with:
php dot 5 dot leenoble at SPAMMENOTspamgourmet dot net 18-Dec-2009 10:01
"Note that FILTER_VALIDATE_EMAIL used in isolation is not enough for most (if
not all) web based registration forms.
It will happily pronounce "yourname" as valid because presumably the
"@localhost" is implied, so you still have to check that the domain portion of
the address exists.
"
So I am surprised Peter recommended it. (?)
AFAICT, I should stick with what I was using:
$emailPattern = '/^[\w\.\-_\+]+@[\w-]+(\.\w{2,4})+$/i'; //
$emailReplacement = 'theEmailAppearsValid';
$emailChecker = preg_replace($emailPattern, $emailReplacement, $emailToCheck);
if($emailChecker == 'theEmailAppearsValid') {
//--theEmailLooksValid, so use it...
} else {
//--theEmailLooksBad, so do not use it...
}
