In 2025, PHP remains a robust and popular server-side scripting language for web development. Sending emails is a common requirement for many web applications, whether it’s for user registration, notifications, or any other functionality. This guide will walk you through the steps of sending emails using PHP in 2025, taking advantage of the latest enhancements and practices.

Prerequisites

Before diving into sending emails with PHP, ensure your environment is set up correctly:

• PHP 8.1 or newer installed on your server.
• Access to an SMTP server - this could be a third-party service like SendGrid, Mailgun, or your own mail server.
• Basic understanding of PHP and Composer.

Sending Email with PHP in 2025

Step 1: Install PHPMailer

PHPMailer is the recommended library for sending emails in PHP due to its simplicity and functionality. Use Composer to install PHPMailer:

composer require phpmailer/phpmailer

Step 2: Configure Your Email

Create a new PHP file (e.g., sendEmail.php) and start by including the PHPMailer classes and configuring your SMTP settings.

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

require 'vendor/autoload.php';

$mail = new PHPMailer(true);

try {
    $mail->isSMTP();
    $mail->Host       = 'smtp.example.com'; // Set the SMTP server to send through
    $mail->SMTPAuth   = true;
    $mail->Username   = 'your_email@example.com'; // SMTP username
    $mail->Password   = 'your_password'; // SMTP password
    $mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;
    $mail->Port       = 587;

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

    // 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}";
}
?>

Step 3: Test Your Email

Upload your PHP script to your server and run it through your browser or command line. Check your recipient email inbox for the test message.
