How to Add PHPMailer for Linux and Windows Hosting

To add PHPMailer to your Linux or Windows Hosting, follow the steps below.

1. Search for and download PHPMailer. Make sure to get it from a reliable source.
   

   Important: To use PHPMailer, you will need a domain name and web hosting because you will need to set up a working email account. If you want to test the script, then create two email accounts: a sender and a recipient.

2. Access your File Manager.
3. Scroll to public_html folder and locate your php.ini file.
4. Inside the public_html folder, create a new folder. Name the new folder, for example, PHPMailer00. Then, open the new folder.
5. Extract the downloaded PHPMailer zipped file.
6. Add the necessary classes in your PHP script. Or you can just use the simple sample script below:
   

   <?php
   
   	require 'PHPMailer00/class.phpmailer.php'; // filepath to the PHPMailer class
           require 'PHPMailer00/class.smtp.php';
   
           $mail = new PHPMailer();
   
           $mail->SMTPDebug = 2;
           $mail->Mailer = "smtp";
           $mail->Host = "localhost";
           $mail->Port = 587;
           $mail->SMTPAuth = true; // turn on SMTP authentication
           $mail->Username = "sender@yourdomain.com"; // SMTP username
           $mail->Password = "password123"; // SMTP password 
           $Mail->Priority = 1;
   
           $mail->AddAddress("recipient@theirdomain.com","Name");
           $mail->SetFrom("info@yourdomain.com", "Info");
           $mail->AddReplyTo("info@yourdomain.com", "Info");
   
           $mail->Subject  = "Hello";
           $mail->Body     = "This is my message.";
           $mail->WordWrap = 50;  
   
           if(!$mail->Send()) {
           echo 'Message was not sent.';
           echo 'Mailer error: ' . $mail->ErrorInfo;
           } else {
           echo 'Message has been sent.';
           }
   
   ?>

   Note: Make sure to put closing tags (?>) at the bottom. Create a new .php file (e.g. test01.php) and save it in the same folder as the extracted PHPMailer folder. Paste the sample script here and then click Save.

7. Replace the following values with your own:

File path	the path of the file that will perform the action or function required for PHPMailer to send emails
Host	your email hosting server
Username	your hosting username
Password	corresponding login password for your hosting
SetFrom	the email address you want the recipient to see as the sender
AddAddress	the email address of the recipient
AddReplyto	the email address you want the recipient to reply to
Subject	the subject of your email
Body	the body or main content of your email




As an alternative to the PHPMailer script, you can also use the simple PHPmail script below instead:

<?php
      $to      = 'recipient@theirdomain.com';
      $subject = 'Email Test';
      $message = 'Hello World';
      $headers = 'From: sender@yourdomain.com' . "\r\n" .
          'CC: info@theirdomain.com';
          'Reply-To: info@yourdomain.com' . "\r\n" .
          'X-Mailer: PHP/' . phpversion();

      mail($to, $subject, $message, $headers);
      echo "Message has been sent.";
      ?>

8. Test if the script works by checking it out on your browser. To do this, put the following url in your address bar:

   yourdomainname.com/folder name/filename.php 

9. If everything is in order and the script works, you will see the following message:

   Message has been sent.

Also, check your recipient email inbox. If you got an email from "sender@yourdomain.com" and it has the message you put in the "body" tag ("This is your message."), then the script works.
