creating an registration form or feedback form, user has to enter, email address on the form which needs to validate manually. This is a good practice for making the application secure and your data from spams. For checking an email address to be valid or not, you have to check is against a regular expression.
An email id of the form id@example.com is a valid email address.
See the code below.
?php
if (isset($_POST['posted'])) {
$email = $_POST['email'];
$results = ereg(“^[^@ ]+@[^@ ]+.[^@ .]+$”, $email, $trashed);
if ($results) {
$isamatch = “Valid”;
} else {
$isamatch = “Invalid”;
}
echo “Email address validation says $email is ” . $isamatch;
}
?>
