How can PHP be used to handle email communication on a web server?

PHP can be used to handle email communication on a web server by utilizing the built-in mail() function. This function allows you to send emails directly from a PHP script by specifying the recipient, subject, message, and additional headers. By using this function, you can easily send emails from your web server without the need for additional email client software. 

$to = 'recipient@example.com';
$subject = 'Test Email';
$message = 'This is a test email sent using PHP.';
$headers = 'From: sender@example.com';

$mailSent = mail($to, $subject, $message, $headers);

if($mailSent){
    echo 'Email sent successfully.';
} else {
    echo 'Failed to send email.';
}
