Create a file to send mail.

In this case our file is sendmail.php.

<?php
    session_start();

    use PHPMailer\PHPMailer\PHPMailer;
    use PHPMailer\PHPMailer\Exception;

    require 'PHPMailer/src/Exception.php';
    require 'PHPMailer/src/PHPMailer.php';
    require 'PHPMailer/src/SMTP.php';

    $mail = new PHPMailer(true);

    $mail->isSMTP();
    $mail->Host = 'smtp.gmail.com';
    $mail->SMTPAuth = true;
    $mail->Username = "[email protected]";  // your own email address from which you want to send email
    $mail->Password = "";   // your app password generated previously.
    $mail->SMTPSecure = 'ssl';
    $mail->Port = 465;

    if (isset($_POST['submit'])) {

        $mail->setFrom('[email protected]');   // your own email, same as the username
        $mail->addAddress($_POST['email']);     // getting email from form.
        $mail->isHTML(true);
        $mail->Subject = $_POST['subject'];     // getting subject form form
        $mail->Body = $_POST['body'];       // getting body from form
        $mail->send();

        $_SESSION['status'] = "email sent successfully";
        $_SESSION['email'] = $_POST['email'];
    } else {
        echo "Please try again";
    }
