How to use PHPMalier

If you want to use PHPMalier, you have to download this script using the composer. If you don’t have an installed composer on your computer, you have to download and install it. It’s not a complicated process. You can install composer like normal windows software. When you have completed the installation of the composer open Command Prompt in your pc which is default software in the Windows operating system. Now go to your application root folder or desired folder using Command Prompt. Now type the following command:

composer require phpmailer/phpmailer

If you have a fast internet connection, it will be download quickly. Wait until all files downloaded.

Once it’s completely downloaded, find out the autoload.php file. Now include in your application file where you have written codes for sending the email. At last, put the following codes in your file where you have written your codes for sending an email.

<?php
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\SMTP;
use PHPMailer\PHPMailer\Exception;
require 'vendor/autoload.php';

$mail = new PHPMailer(true);
$mail->SMTPDebug = 0; // Enable verbose debug output
$mail->isSMTP(); // Send using SMTP
$mail->Host       = 'smtp.gmail.com'; // Set the SMTP server to send through
$mail->SMTPAuth   = true; // Enable SMTP authentication
$mail->Username   = 'user@example.com'; // SMTP username
$mail->Password   = 'secret'; // SMTP password
$mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;        
$mail->Port       = 587;

$mail->setFrom('from@example.com', 'Mailer');
$mail->addAddress('joe@example.net', 'Joe User');
$mail->isHTML(true);
$mail->Subject = 'Here is the subject';
$mail->Body    = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

if($mail->send()){
echo 'Message has been sent';
}

Now, change some codes here. You have to change the host if you are using your own hosting account server. If you want to use the Gmail account server don’t change Host. You have to change also the username and password. Give your own email account password and username.

Now you’re all set. When you will reload your file in browser, this code will be sent an email to your desired email address.
