Email communication remains a critical aspect of web development even in 2025. Whether you are sending confirmation emails, newsletters, or contact form responses, PHP provides robust options for sending emails effectively. In this article, we explore the latest practices to send an email using PHP.

Prerequisites

Before diving into email sending, ensure you have:

• A server with PHP installed.
• Access to an SMTP server (optional but recommended for reliability).
• Basic understanding of PHP syntax.

Step-by-Step Guide to Send Email in PHP

1. Using the mail() Function

The simplest way to send an email in PHP is by using the built-in mail() function. However, this method has limitations, particularly with deliverability and reliability. Here’s a basic example:

<?php
$to      = 'recipient@example.com';
$subject = 'Test Email';
$message = 'Hello! This is a test email.';
$headers = 'From: sender@example.com';

if(mail($to, $subject, $message, $headers)) {
    echo 'Email sent successfully!';
} else {
    echo 'Failed to send email.';
}
?>

2. Using PHPMailer

For more controlled and reliable email sending, consider using the PHPMailer library. This is especially important when dealing with SMTP authentication:

composer require phpmailer/phpmailer

Below is a basic example using PHPMailer:

<?php
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'vendor/autoload.php';

$mail = new PHPMailer(true);

try {
    //Server settings
    $mail->SMTPDebug = 2;                                       // Enable verbose debug output
    $mail->isSMTP();                                            // Set mailer to use SMTP
    $mail->Host       = 'smtp.example.com';                     // Specify main and backup SMTP servers
    $mail->SMTPAuth   = true;                                   // Enable SMTP authentication
    $mail->Username   = 'user@example.com';                     // SMTP username
    $mail->Password   = 'password';                             // SMTP password
    $mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;          // Enable TLS encryption, `PHPMailer::ENCRYPTION_SMTPS` encouraged
    $mail->Port       = 587;                                    // TCP port to connect to

    //Recipients
    $mail->setFrom('from@example.com', 'Mailer');
    $mail->addAddress('recipient@example.com', 'Joe User');     // Add a recipient

    // Content
    $mail->isHTML(true);                                        // Set email format to HTML
    $mail->Subject = 'Here is the subject';
    $mail->Body    = 'This is the HTML message body <b>in bold!</b>';
    $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}";
}
?>

3. Utilize CakePHP Email (2023) Capabilities
