以下是发送电子邮件的PHP代码：

<?PHP
$to = "myaccount@gmail.com";

// subject
$subject = "Test mail";

// message
$message = file_get_contents("index.html");

// from
$from = "myaccount@gmail.com";

// To send HTML mail,the Content-type header must be set
$headers = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";

// Additional headers
$headers .= "From:" . $from;

// Mail it
mail($to,$subject,$message,$headers);

echo "Mail Sent.";
?>
