How to send plain text emails using PHP and PHPMAILER?

Overview:
In web application development, it is often necessary to send emails, whether it is sending verification emails, notification emails, or marketing emails. PHPMAILER is a very popular email sending class library in PHP. It provides rich functions and a simple and easy-to-use interface. This article will introduce how to use PHP and PHPMAILER to send plain text emails and provide corresponding code examples.

Steps:

1. Download the PHPMAILER class library
   First, we need to download the PHPMAILER class library and import it into our project. The latest version of PHPMAILER can be downloaded from the PHPMAILER official website (https://github.com/PHPMailer/PHPMailer).
2. Reference PHPMAILER class library
   Extract the downloaded PHPMAILER class library into the project directory, and introduce the PHPMAILER class library into our PHP code. This can be achieved using the following code:

require 'path/to/PHPMailer/PHPMailerAutoload.php';

3. Create a mail object and set attributes
   Before sending an email, we need to create an instance of PHPMAILER and set related attributes, such as recipient Person, sender, subject and email content, etc. The following is a sample code:

$mail = new PHPMailer;

$mail->setFrom('sender@example.com', 'Sender Name');
$mail->addAddress('recipient@example.com', 'Recipient Name');
$mail->Subject = 'Example Subject';
$mail->Body = 'This is the body of the email.';

4. Configure mail server information
   To send mail, we need to configure the relevant information of the SMTP server, including server address, user name, password, port, etc. The following is the sample code:

$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->SMTPAuth = true;
$mail->Username = 'user@example.com';
$mail->Password = 'secret';
$mail->Port = 587;

5. Send email
   Once the configuration is completed, you can send emails by calling the send() method of PHPMAILER. The following is a sample code:

if ($mail->send()) {
    echo 'Email sent successfully!';
} else {
    echo 'Email could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
}

After completing the above steps, we can use PHP and PHPMAILER to send plain text emails. According to actual needs, you can customize email content, subject, recipients, senders and other information.

Summary:
This article introduces how to use PHP and PHPMAILER to send plain text emails. By downloading and referencing the PHPMAILER class library, setting email properties, configuring SMTP server information, and finally calling the send() method, you can send emails. I hope this article is helpful to your email sending needs in web application development.
