Validate Email Domain Php Updated Here

// 2. Validate Syntax if (filter_var($sanitizedEmail, FILTER_VALIDATE_EMAIL) !== false) echo "Syntax is valid."; else echo "Invalid email syntax.";

While regex can validate the syntax of an email address, it tells you nothing about its validity . A user entering john.doe@fake-domain-12345.com will pass almost every regex check, but the email is useless because the domain does not exist. validate email domain php

First, ensure the email has a proper structure: // 2. Validate Syntax if (filter_var($sanitizedEmail

if (!empty($records)) return true;

return false;

Wrong.
