How to send email using PHP Mailer library and hosting SMTP

The email system plays an important role in a website. If you want to send email from your website to the desired email with 100% percent delivery surety then you should use the PHP Mailer library. PHPMailer is a code library to send emails safely and easily via PHP code from a web server. In this tutorial, we will send emails using PHP mailer and Hosting SMTP. As you know that we can create a business email and password from the Cpanel. We will use hosting business email and password to connect PHP mailer to hosting SMTP. In this tutorial, we will create a form to input email, name, subject, and message body. The HTML form will be used to send email messages from the website through PHPMailer and hosting SMTP. You will learn the complete installation of PHPMailer with the composer.

 PHPMailer installation and loading – 

First of all, we need to download PHPMAILER library. Kindly download it in the zip file and extract it from where you want to create your project. 
Rename folder name PHPMailer-master to PHPMailer. 

How to install composer and use of command line in the project folder? 

In this step, you will need to install composer. If you want to install composer on your computer then you have to download the composer exe file and install it. 
You can download the composer from here. Before downloading composer, make sure you are using a local server or if you are working on the live server then you will not need to download composer. 
Now, run a command in the same folder where the PHPMailer folder is available. 
1.    Search run on your computer and enter cmd. 

Run Command Line
2.    After this, command prompt will open. 
3.    Here, you have to move the project directory. 
Like -  Commands 
cd c:
Now you are in c drive.
cd xampp\htdocs\smtp
Here, smtp is a project folder name. You can set your project folder where the PHPMailer library is available. 
Now, run a command to install the composer 

composer require phpmailer/phpmailer

Or if you want to install composer on Hosting live server then find the terminal command line from the Cpanel or anywhere from your hosting and move to your project path using cd 

Terminal on Cpanel Hosting
Like – 
cd public_html\foldername 
then use the same command 
composer require phpmailer/phpmailer
If you are unable to do that then watch this video. 
Don’t, worry about that , if you are unable to install composer then you can use PHPMailer without composer. 
Now, that the composer has been installed then follow the next step. 

Create an HTML form to send email using PHP mailer and Hosting SMTP – 

In this tutorial, we are going to create an HTML form for the single and multiple emails sending processes. 
In the same PHP file, we will use the PHPMailer code. 
Now, create a form.php PHP file and paste the code below. 


<?php use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\SMTP;
use PHPMailer\PHPMailer\Exception;

//Load Composer's autoloader
require 'vendor/autoload.php';
$mail = new PHPMailer(true);
<!DOCTYPE html>
	<meta charset="utf-8">
	<meta name="viewport" content="width=device-width, initial-scale=1">
	<title>Email sending using PHPMAILER and Hosting SMTP  </title>
	<link rel="stylesheet" type="text/css" href="style.css">
<div class="container">

try {
    //Server settings
    //$mail->SMTPDebug = SMTP::DEBUG_SERVER;                      //Enable verbose debug output
    $mail->isSMTP();                                            //Send using SMTP
    $mail->Host       = '';                     //Set the SMTP server to send through
    $mail->SMTPAuth   = true;                                   //Enable SMTP authentication
    $mail->Username   = '';                     //SMTP username
    $mail->Password   = 'technosmarter12';                               //SMTP password
    $mail->SMTPSecure = 'tls';            //Enable implicit TLS encryption
    $mail->Port       = 587;                                    //TCP port to connect to; use 587 if you have set `SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS`

    $mail->setFrom('', 'Techno Smarter');
    //for multiple emails
    // $toarray=explode(",",$to);
    // foreach($toarray as $row)
    // {
    //      $mail->addAddress($row); 
    // }
    //for single email 
       $mail->addAddress($to,$name);     //Add a recipient              //Name is optional
    $mail->addReplyTo('', 'Techno Smarter');

    //$mail->addAttachment('/var/tmp/file.tar.gz');         //Add attachments
    //$mail->addAttachment('/tmp/image.jpg', 'new.jpg');    //Optional name

    $mail->isHTML(true);                                  //Set email format to HTML
    $mail->Subject = $subject;
    $mail->Body    = $msg;
    //$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

    echo '<div class="success ">Message has been sent</div>';
} catch (Exception $e) {
    echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}";

    height: 34px;
    padding: 6px 12px;
    font-size: 14px;
    color: #555;
    background-color: #fff;
    border: 1px solid #ccc;
    border-radius: 4px;
.btn-primary {
    padding: 6px 12px;
    font-size: 14px;
    font-weight: 400;

margin-top: 6%;
background-color: #fff;
padding: 30px;
padding-right: 60px;
box-shadow: 10px 5px 5px grey;

How to use PHPMailer without composer? 

Yes, you can use PHPMailer without composer. If you are getting errors like these – 
Warning: require(vendor/autoload.php): failed to open stream: No such file or directory 

Fatal error: require(): Failed opening required 'vendor/autoload.php' (include_path='C:xamppphpPEAR') 
Or command line error – 
'composer' is not recognized as an internal or external command,
operable program or batch file.

You can remove these errors by following the details above but if you are unable to do that then use PHPMailer library without composer.  
 You will need to change the code line – 

require 'vendor/autoload.php';


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

Here, PHPMailer is a folder name that was downloaded and extracted from the zip and renamed from PHPMailer-master to PHPMailer. 
Now, you are able to use the PHPMailer library without a composer. 
In this way, you can use the PHPMailer library with hosting SMTP.
