我想用 utf8 编码发送这封电子邮件的消息..
我能为此做些什么
include 'functions.php';
$name = stripslashes($_POST['name']);
$email = trim($_POST['email']);
$subject = stripslashes($_POST['subject']);
$message = stripslashes($_POST['message']);
$cap=strtoupper($_POST['cap']);
$error = '';
$mail = mail(WEBMASTER_EMAIL,$subject,$message,
"From: ".$name." <".$email.">\r\n"
."Reply-To: ".$email."\r\n"
."X-Mailer: PHP/" . phpversion());
我可以用 utf8 发送什么?
