This function CheckEmail() verifies if a valid e-mail address was added. For the verification I used a regular expression. If the return value is 1, a valid e-mail address was added. If the return value is 0, an invalid e-mail address was added.
<?php
#This function verifies if a valid e-mail address was added.
function CheckEmail($email) {
return ereg("^[^@ ]+@[^@ ]+\.[^@ \.]+$", $email);
}
#Verify if e-mail address is valid.
if (CheckEmail($email)!=1) {
echo "An invalid e-mail address was added!";
}
else {
echo "Thanks for the registration!";
}
?>
