Sending Emails from XAMPP Localhost using PHP: A Step-by-Step Guide

Introduction:

XAMPP is a popular software package that provides an easy way to set up a local development environment for web applications. Sending emails from XAMPP localhost using PHP is a common requirement during application development. In this article, we will walk through a step-by-step guide on how to configure XAMPP to send emails using PHP's built-in mail() function.


Step 1: Install and Configure XAMPP:

First, download and install XAMPP from the official Apache Friends website (https://www.apachefriends.org/index.html) based on your operating system. Follow the installation wizard and choose the desired components, such as Apache and PHP.


Step 2: Configure the SMTP Server:

To send emails from localhost, we need to configure XAMPP to use an SMTP (Simple Mail Transfer Protocol) server. Locate the php.ini file within your XAMPP installation directory (e.g., C:\xampp\php\php.ini for Windows).

Open the php.ini file with a text editor and search for the following section:

[mail function]

; For Win32 only.

SMTP = localhost

smtp_port = 25

Uncomment the SMTP line by removing the semicolon (;) at the beginning and set the value to the SMTP server address provided by your email service provider. Additionally, you may need to change the smtp_port value based on your provider's requirements (typically 25 or 587).


Step 3: Test the Email Sending Functionality:

To test if email sending is working correctly, create a new PHP file (e.g., send_email.php) in your XAMPP document root directory (htdocs).

In the PHP file, add the following code:

<?php

$to = "recipient@example.com";

$subject = "Test Email";

$message = "This is a test email sent from localhost.";

$headers = "From: your-email@example.com" . "\r\n" .

    "Reply-To: your-email@example.com" . "\r\n" .

    "X-Mailer: PHP/" . phpversion();

if (mail($to, $subject, $message, $headers)) {

    echo "Email sent successfully.";

} else {

    echo "Failed to send email.";

}

?>

Replace recipient@example.com with the recipient's email address and your-email@example.com with your own email address.

Save the PHP file and access it through your web browser by entering http://localhost/send_email.php. If everything is configured correctly, you should see a message indicating whether the email was sent successfully or if there was a failure.


Step 4: Handling Email Delivery Issues:

Sometimes, emails sent from localhost may end up in the recipient's spam or junk folder. To improve the chances of successful email delivery, you can set up additional configurations such as DKIM (DomainKeys Identified Mail) and SPF (Sender Policy Framework) records for your domain. These records help validate the authenticity of the email and increase the chances of it being delivered to the recipient's inbox.


Conclusion:

Configuring XAMPP to send emails from the localhost using PHP's mail() function is a straightforward process. By modifying the php.ini file with the correct SMTP server details and using the mail() function, you can send test emails during the development phase of your applications. Remember to handle any potential email delivery issues by implementing additional measures like DKIM and SPF records. With these steps in place, you can ensure that your email functionality works smoothly before deploying your application to a live server.
