Лучшая практика ..
composer require phpmailer/phpmailer
Для следующего файла sendmail.php просто требуется следующее
# use namespace
use PHPMailer\PHPMailer\PHPMailer;
# require php mailer
require_once "../vendor/autoload.php";
//PHPMailer Object
$mail = new PHPMailer;
//From email address and name
$mail->From = "from@yourdomain.com";
$mail->FromName = "Full Name";
//To address and name
$mail->addAddress("recepient1@example.com", "Recepient Name");
$mail->addAddress("recepient1@example.com"); //Recipient name is optional
//Address to which recipient will reply
$mail->addReplyTo("reply@yourdomain.com", "Reply");
//CC and BCC
$mail->addCC("cc@example.com");
$mail->addBCC("bcc@example.com");
//Send HTML or Plain Text email
$mail->isHTML(true);
$mail->Subject = "Subject Text";
$mail->Body = "<i>Mail body in HTML</i>";
$mail->AltBody = "This is the plain text version of the email content";
if(!$mail->send())
{
echo "Mailer Error: " . $mail->ErrorInfo;
}
else
{
echo "Message has been sent successfully";
}
