✉️ E-Mail Address Validator for PHP


The best way to validate an e-mail address is still to send a duplicate opt-in-mail, when the user clicks on the link, it was a valid e-mail address!


The recommended installation way is through Composer.

$ composer require voku/email-check


Example 1:

$emailCheck = EmailCheck::isValid("lars@moelleken.org");

// true

Example 2: (check for example-domain)

$emailCheck = EmailCheck::isValid("lars@example.com", true);

// false

Example 3: (check for typo in domain)

$emailCheck = EmailCheck::isValid("lars@-tonline.de", false, true);

// false

Example 4: (check for temporary-domain)

$emailCheck = EmailCheck::isValid("lars@30minutemail.com", false, false, true);

// false
