For validating email, we create a user defined function named is_valid_email
. You can paste this function to your php file and call the function wherever needed.
This function accepts two parameters, in which one is a default parameter, which we do not need to give value for that parameter. Another one parameter is email
. While calling the function just supply the email to be verified as the first parameter. Second we can leave as blank.
function is_valid_email($email, $test_mx = false) {
if (eregi("^([_a-z0-9-]+)(\.[_a-z0-9-]+)*@([a-z0-9-]+)(\.[a-z0-9-]+)*(\.[a-z]{2,4})$", $email))
if ($test_mx) {
list($username, $domain) = split("@", $email);
return getmxrr($domain, $mxrecords);
} else
return true;
else
return false;
}
