PHP邮件发送功能是Web开发中必不可少的功能之一，通过邮件发送，客户可以及时收到网站相关信息，如注册、订单、忘记密码等。本文将介绍10个PHP邮件发送函数，帮助你轻松实现电子邮件功能。
1. mail()
mail()是PHP自带的邮件发送函数，它支持SMTP协议和sendmail程序。使用此函数，发送邮件非常方便，只需要设置邮件的收件人、发件人、邮件主题、内容等即可。
示例代码：
$to = 'receiver@example.com';
$subject = 'Test email';
$message = 'Hello world';
$headers = 'From: sender@example.com' . "\r
" .
'Reply-To: sender@example.com' . "\r
" .
'X-Mailer: PHP/' . phpversion();
mail($to, $subject, $message, $headers);
2. PHPMailer
PHPMailer是一个流行的PHP邮件发送类，不仅支持SMTP协议和sendmail程序，还支持TLS和SSL加密协议、HTML邮件、附件等功能。使用此类库，发送邮件更加灵活，功能更加强大。
示例代码：
require_once('phpmailer/PHPMailerAutoload.php');
$mail = new PHPMailer;
$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 = 'sender@example.com'; // SMTP username
$mail->Password = 'password'; // SMTP password
$mail->SMTPSecure = 'tls'; // Enable TLS encryption, ssl also accepted
$mail->Port = 587; // TCP port to connect to
$mail->setFrom('sender@example.com', 'Sender Name');
$mail->addAddress('receiver@example.com', 'Receiver Name'); // Add a recipient
$mail->isHTML(true); // Set email format to HTML
$mail->Subject = 'Test email';
$mail->Body = 'Hello world';
if(!$mail->send()) {
echo 'Message could not be sent.';
echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
echo 'Message has been sent';
}

$transport = Swift_SmtpTransport::newInstance('smtp.example.com', 587, 'tls')
->setUsername('sender@example.com')
->setPassword('password');
$mailer = Swift_Mailer::newInstance($transport);
$message = Swift_Message::newInstance('Test email')
->setFrom(array('sender@example.com' => 'Sender Name'))
->setTo(array('receiver@example.com' => 'Receiver Name'))
->setBody('Hello world', 'text/html');
if ($result = $mailer->send($message)) {
echo "Message sent successfully
";
} else {
echo "Error: ", print_r($result, true), "
";
}
4. PEAR::Mail

'port' => 587,
'auth' => true,
'username' => 'sender@example.com',
'password' => 'password'
);
$to = 'receiver@example.com';
$subject = 'Test email';
$message = 'Hello world';
$headers = array(
'From' => 'sender@example.com',
'To' => $to,
'Subject' => $subject
);
$mail = Mail::factory('smtp', $smtp);
if ($mail->send($to, $headers, $message)) {
echo "Message sent successfully
";
} else {
echo "Error: ", $mail->getMessage(), "
";
}

if ($smtp->send($mail)) {
echo "Message sent successfully
";
} else {
echo "Error: ", $smtp->getLastTransportException()->getMessage(), "
";
}
