PHP inakuja na mail() function inayoruhusu:

Kutuma emails moja kwa moja kutoka website yako.

Kutuma notifications, confirmations, au alerts kwa users.

Function hii inaweza kutumika kwa contact forms, registration confirmations, password resets, etc.

Note: Kwa production, kutumia SMTP (PHPMailer au SwiftMailer) ni zaidi reliable kuliko mail().

⚙️ 2. Simple Email Notification Example
<?php
$to = "user@example.com"; // email ya user
$subject = "Welcome to Our Website!";
$message = "
<html>
<head>
<title>Welcome Email</title>
</head>
<body>
<h2>Hi there!</h2>
<p>Thank you for registering on our website. We're excited to have you.</p>
</body>
</html>
";

// Set content-type for HTML email
$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=UTF-8" . "\r\n";

// Additional headers
$headers .= "From: no-reply@yourdomain.com" . "\r\n";
$headers .= "Reply-To: support@yourdomain.com" . "\r\n";

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


💡 Maelezo:

Content-type:text/html inaruhusu HTML emails.

From na Reply-To headers husaidia deliverability.

🧩 3. Sending Email After User Registration
<?php
// Assume user just registered
$user_email = $_POST['email'];
$user_name = $_POST['username'];

$subject = "Registration Confirmation";
$message = "
<html>
<body>
<h3>Welcome, $user_name!</h3>
<p>Your registration was successful. Enjoy our services.</p>
</body>
</html>
";

$headers = "MIME-Version: 1.0\r\n";
$headers .= "Content-type:text/html;charset=UTF-8\r\n";
$headers .= "From: no-reply@yourdomain.com\r\n";

mail($user_email, $subject, $message, $headers);


Function inatumwa baada ya form submission au user creation.

🔑 4. Vidokezo vya Usalama na Best Practices

Validate user email – avoid sending to invalid emails.

Sanitize user input – prevent email header injection.

Use HTML emails sparingly – provide plain text fallback.

Consider SMTP library – PHPMailer au SwiftMailer kwa reliable delivery.

Limit emails per user – avoid spam filters.

✅ 5. Hitimisho

PHP mail() function ni rahisi kwa simple email notifications.

Kwa systems kubwa au production, SMTP libraries zinahakikisha deliverability zaidi.

Best practices: validate emails, sanitize inputs, use proper headers, and optionally switch to PHPMailer.
