How to use the Mailer library in PHP?

You can call the Mailer library in PHP by following these steps:

1. The file composer.json

{
    "require": {
        "phpmailer/phpmailer": "^6.0"
    }
}

Next, run composer install to install the Mailer library.

1. Include the autoload file for the Mailer library in the files where the Mailer library is needed.

require 'vendor/autoload.php';

1. PHPMailer is a software library used for sending emails in PHP.

use PHPMailer\PHPMailer\PHPMailer;

$mail = new PHPMailer();

$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->Port = 587;
$mail->SMTPAuth = true;
$mail->Username = 'your-email@example.com';
$mail->Password = 'your-email-password';
$mail->SMTPSecure = 'tls';
$mail->setFrom('your-email@example.com', 'Your Name');
$mail->addAddress('recipient@example.com', 'Recipient Name');
$mail->Subject = 'Testing PHPMailer';
$mail->Body = 'This is a test email sent using PHPMailer.';

1. Transmit the information.

if($mail->send()) {
    echo 'Email sent successfully';
} else {
    echo 'Error sending email: ' . $mail->ErrorInfo;
}

In the above code, you can configure relevant settings according to your actual needs, such as the address, port number, username, and password of the SMTP server. Additionally, you can also include attachments, and customize the format of the email.

The above are the basic steps for using the Mailer library in PHP. Depending on specific needs, further configurations and operations can also be performed.
