Sample Usage

Simply import the Emailvalidator.class.php file into your project if you are not using dependency injection.

require __DIR__ . '/src/com/rottingham/EmailValidator/EmailValidator.class.php';

Valiate Email

To validate an Email string, use the EmailValidator::validate(email) method;

$email = '[email protected]';
$isValid = EmailValidator\EmailValidator::validate($email);
var_dump($isValid);

Check if Email Exists

To determine if the Emai actaully exists on the mail server, use the EmailValidator::exists(email) method;

$email = '[email protected]';
$exists = EmailValidator\EmailValidator::exists($email);
var_dump($exists);

Note: EmailValidator::exists(url) calls EmailValidator\SmtpLookup\SmtpLookup::lookup(email) and requests from the mail server whether or not the address book record exists. This could fail if your IP address and/or mail server have been blacklisted.

Email Lookup

You can use the EmailValidator\SmtpLookup.class.php class seperately by importing it into your project.

require __DIR__ . '/src/com/rottingham/SmtpLookup/SmtpLookup.class.php';
