PHP SMTP 邮件发送类：简单实现邮件发送功能
以下是一个使用 SMTP 发送邮件的 PHP 类示例代码：
class SMTPMailer {
private $host;
private $port;
private $username;
private $password;
public function __construct($host, $port, $username, $password) {
$this->host = $host;
$this->port = $port;
$this->username = $username;
$this->password = $password;
}
public function sendMail($to, $from, $subject, $body) {
$headers = array(
'MIME-Version: 1.0',
'Content-type: text/html; charset=utf-8',
'From: ' . $from,
'Reply-To: ' . $from,
'X-Mailer: PHP/' . phpversion()
);
$message = '<html><body>';
$message .= '<h1>' . $subject . '</h1>';
$message .= '<p>' . $body . '</p>';
$message .= '</body></html>';
$smtp = fsockopen($this->host, $this->port, $errno, $errstr, 10);
if (!$smtp) {
throw new Exception('SMTP connection failed: ' . $errstr);
}
$this->getResponse($smtp);
fwrite($smtp, 'EHLO ' . $this->host . "\r\n");
$this->getResponse($smtp);
fwrite($smtp, 'AUTH LOGIN' . "\r\n");
$this->getResponse($smtp);
fwrite($smtp, base64_encode($this->username) . "\r\n");
$this->getResponse($smtp);
fwrite($smtp, base64_encode($this->password) . "\r\n");
$this->getResponse($smtp);
fwrite($smtp, 'MAIL FROM: <' . $this->username . '>' . "\r\n");
$this->getResponse($smtp);
fwrite($smtp, 'RCPT TO: <' . $to . '>' . "\r\n");
$this->getResponse($smtp);
fwrite($smtp, 'DATA' . "\r\n");
$this->getResponse($smtp);
fwrite($smtp, 'Subject: ' . $subject . "\r\n");
fwrite($smtp, implode("\r\n", $headers) . "\r\n");
fwrite($smtp, "\r\n" . $message . "\r\n");
fwrite($smtp, '.' . "\r\n");
$this->getResponse($smtp);
fwrite($smtp, 'QUIT' . "\r\n");
$this->getResponse($smtp);
fclose($smtp);
}
private function getResponse($smtp) {
$response = '';
while (substr($response, 3, 1) != ' ') {
if (!($line = fgets($smtp, 256))) {
throw new Exception('SMTP error: did not receive valid response from server');
}
$response .= $line;
}
return $response;
}
}
// 使用示例：
$mailer = new SMTPMailer('smtp.example.com', 25, 'your-username', 'your-password');
$mailer->sendMail('to@example.com', 'from@example.com', 'Test Email', 'This is a test email.');
请注意，这只是一个简单的示例，具体的 SMTP 服务器设置和身份验证方法可能会有所不同。您需要根据您自己的 SMTP 服务器配置进行必要的修改。
