使用PHP

Question

我对PHP很陌生。我需要从网页发送一封电子邮件，并认为我的代码很好，但它没有发送任何内容。我无法看到我做错了什么......

<?php
echo ("Thank you.")
$msg = "Some email message for testing. Please disregard if you receive this in your email.";
$msg = wordwrap($msg,70);
mail("email1@internet.com","Subject Verbiage",$msg);
mail("email2@internet.com","Subject Verbiage",$msg);
?> 

非常感谢任何帮助。
