To send a file to E-mail from PHP, you can use the standard mail sending functions, but it is more convenient to use a library, for example, Swfitmailer: https://swiftmailer.symfony.com/docs/introduction.html
The sending code can be something like this:

// Create the Transport
$transport = (new Swift_SmtpTransport('smtp.gmail.com', 993))
  ->setUsername('[email protected]')
  ->setPassword('your password')
;

// Create the Mailer using your created Transport
$mailer = new Swift_Mailer($transport);

// Create a message
$message = (new Swift_Message('Тема сообщения'))
  ->setFrom(['[email protected]' => 'John Doe'])
  ->setTo($_POST['to']) // на форме должно быть поле <input name="to">
  ->attach(
    Swift_Attachment::fromPath('/path/to/file.pdf')
  );

// Send the message
$result = $mailer->send($message);
