Send email using the GMail SMTP server from a PHP page

Sending Email using GMail SMTP Server from a PHP Page: Common Issues and Easy Solutions

So, you're trying to send an email through GMail's SMTP server from a PHP page, but you're running into some trouble? No worries, we've got you covered! 📧💥

The Error and the Code 😱🔍

The error you're encountering looks like this:

authentication failure [SMTP: SMTP server does no support authentication (code: 250, response: mx.google.com at your service, [98.117.99.235] SIZE 35651584 8BITMIME STARTTLS ENHANCEDSTATUSCODES PIPELINING)]

This error message clearly states that the SMTP server doesn't support authentication. The code you provided seems to be correct, and you're using the Mail package to send the email. But why are you still getting this error? Let's find out!

The Issue: Insecure Connection 😬🔐

The problem lies in the connection settings of the SMTP server. By default, GMail's SMTP server requires a secure (TLS) connection to authenticate. However, the code you provided doesn't specify any encryption.

The Solution: Enabling Encryption 🔒🚀

To fix this issue, you need to enable encryption in your PHP code. You can do this by adding the following line before calling $smtp->send:

$smtp->startTLS();

This line tells the Mail package to initiate a secure connection using TLS encryption.

Updated PHP Code 💻✨

Here's the updated version of your PHP code with the necessary change:

<?php

require_once "Mail.php";

$from = "Sandra Sender <sender@example.com>";
$to = "Ramona Recipient <ramona@microsoft.com>";
$subject = "Hi!";
$body = "Hi,\n\nHow are you?";

$host = "smtp.gmail.com";
$port = "587";
$username = "testtest@gmail.com";
$password = "testtest";

$headers = array (
  'From' => $from,
  'To' => $to,
  'Subject' => $subject
);

$smtp = Mail::factory('smtp', array (
  'host' => $host,
  'port' => $port,
  'auth' => true,
  'username' => $username,
  'password' => $password
));

$smtp->startTLS(); // Enable encryption

$mail = $smtp->send($to, $headers, $body);

if (PEAR::isError($mail)) {
  echo("<p>" . $mail->getMessage() . "</p>");
} else {
  echo("<p>Message successfully sent!</p>");
}

?>

With the addition of $smtp->startTLS(), your code will now establish a secure connection with GMail's SMTP server, allowing successful email delivery.

Your Turn! 📝🤩

Now that you've got the solution to your problem, it's time to put it into action! 🚀 Update your code with the changes discussed above and enjoy sending emails through GMail's SMTP server using PHP.
