How to Send Mail Using PHPMailer: A Comprehensive Guide
As an IT professional or a programmer, sending emails programmatically is an integral part of your job. While PHP's built-inmail() function can handle this task, its limitations and complexity can be a deterrent. This is where PHPMailer comes into the picture. PHPMailer is a widely recognized open-source PHP library that simplifies the process of sending emails using PHP. This article provides an in-depth guide on how to send mail using PHPMailer, offering insights into its setup, advantages over other methods, and more.
Unveiling PHPMailer
PHPMailer emerged as an excellent alternative to PHP'smail() function due to its simplicity and flexibility. It was first released in 2001 and has since become a favorite among PHP developers. It's now used by popular PHP content management systems like WordPress, Drupal, and Joomla.
Why Choose PHPMailer Over PHP's mail() function?
While PHP's mail() function allows you to send emails using setup PHP scripts, PHPMailer offers a more straightforward, object-oriented interface. Here are a few reasons why developers prefer PHPMailer:
- PHPMailer provides an easy-to-use API, eliminating the need for complex header strings and dirty code.
- It allows you to send emails using the Simple Mail Transfer Protocol (SMTP), thereby avoiding the need for a local mail server.
- PHPMailer supports advanced features such as authentication, encryption, attachments, and HTML emails.
- It provides error messages in over 40 languages, making debugging easier.
Setting Up PHPMailer
Installing PHPMailer is a straightforward process, especially when using Composer. Here's a step-by-step guide on how to install PHPMailer:
1. Connect to your server using SSH.
2. Navigate to your project directory using the `cd` command.
3. Run the following command to install PHPMailer: `composer require phpmailer/phpmailer`
Sending Emails Using PHPMailer
PHPMailer allows you to send emails using either the built-in PHPmail() function or an external PHP mailing package. This flexibility makes it a popular choice for many developers.
Sending Email from a Local Server
The simplest way to send an email using PHPMailer is from a local server. Here's a sample code snippet that demonstrates this:
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;
require 'path/to/PHPMailer/src/Exception.php';
require 'path/to/PHPMailer/src/PHPMailer.php';
require 'path/to/PHPMailer/src/SMTP.php';
$mail = new PHPMailer(true);
try {
//Server settings
$mail->SMTPDebug = 2;
$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->SMTPAuth = true;
$mail->Username = 'your-email@example.com';
$mail->Password = 'your-email-password';
$mail->SMTPSecure = 'tls';
$mail->Port = 587;
//Recipients
$mail->setFrom('your-email@example.com', 'Your Name');
$mail->addAddress('recipient@example.com', 'Recipient Name');
//Content
$mail->isHTML(true);
$mail->Subject = 'Email Subject';
$mail->Body = 'This is the HTML message body in bold!';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';
$mail->send();
echo 'Message has been sent';
} catch (Exception $e) {
echo 'Message could not be sent. Mailer Error: ', $mail->ErrorInfo;
}
?>
- The
usekeyword is used to import the necessary PHPMailer classes into the global namespace. - The
requirestatements include the necessary PHPMailer library files. - A new PHPMailer object is created with exception handling enabled (
new PHPMailer(true)). - The SMTP settings, recipients, and content are set using the PHPMailer object's methods.
- The
send()method is called to send the email.
Sending Email with Attachments
PHPMailer also allows you to send emails with attachments. Here's an example:Sending Email with Attachments
PHPMailer also allows you to send emails with attachments. Here's an example:
//...
$mail = new PHPMailer(true);

//Recipients
//...
//Attachments
$mail->addAttachment('/path/to/file.txt'); // Add attachments
$mail->addAttachment('/path/to/image.jpg', 'new.jpg'); // Optional name
//Content
//...
$mail->send();
echo 'Message has been sent';
} catch (Exception $e) {
echo 'Message could not be sent. Mailer Error: ', $mail->ErrorInfo;
}
?>
Using SMTP
SMTP (Simple Mail Transfer Protocol) is a protocol used by mail clients to send an email request to a mail server. Once the mail server verifies the email, it sends it to the destination mail server. Here's an example of sending an email using an SMTP server: Installing PHPMailer is a straightforward process, especially when using Composer. Here's a step-by-step guide on how to install PHPMailer:
//...
$mail = new PHPMailer(true);
try {
//Server settings
$mail->SMTPDebug = 2;
$mail->isSMTP();
$mail->Host = 'smtp.gmail.com';
$mail->SMTPAuth = true;
$mail->Username = 'your-email@gmail.com';
$mail->Password = 'your-email-password';
$mail->SMTPSecure = 'tls';
$mail->Port = 587;
//Recipients
//...
//Content
//...
$mail->send();
echo 'Message has been sent';
} catch (Exception $e) {
echo 'Message could not be sent. Mailer Error: ', $mail->ErrorInfo;
}
?>
