Exempel på bra metod att validera PHP formulär? - Flashback

$email = "john.doe@example.com"; // Remove all illegal characters from email. $email = filter_var ($email, FILTER_SANITIZE_EMAIL); // Validate e-mail. if (filter_var ($email, FILTER_VALIDATE_EMAIL)) {. The filter_var function accepts three parameters but for testing an email address only the first two are needed. The first parameter is the data to filter, in this instance an email address, and the second the filter type, in this instance FILTER_VALIDATE_EMAIL. filter_var function returns the filtered data or false if the filter fails. This makes filter_var fairly useless in my opinion: the more unicode email addresses appear in the wild, the more legitimate email addresses will fail, which is especially the case for countries like China or Brazil, where there is an obvious demand for these addresses.
