这有什么问题。。

我正在尝试向邮件发送消息，但接收方未收到消息.. 我的代码有什么问题？或者你有什么建议吗？请帮忙：

这是我的代码：

<?php

if(isset($_POST['subject'], $_POST['sender'], $_POST['receiver'], $_POST['body']))        {
    //Validate Subject
        if(empty($_POST['subject'])) {
            $errors[] = "Please enter a subject";
        } else{
            $subject = htmlentities($_POST['subject']);
        }

    //Validate Sender Email
        if(empty($_POST['sender'])) {
            $errors[] = "Please enter a valid eMail Address";
        } else if(strlen($_POST['sender']) > 347) {
            $errors[] = "Email is too long. Please provide a valid email address";
        } else if(filter_var($_POST['sender'], FILTER_VALIDATE_EMAIL) ===  false) {
            $errors[] = "Please provide a valid eMail address";
        }else{
            $email = "<" .htmlentities($_POST['sender']). ">";
        }

    //Validate Receiver's Email
        if(empty($_POST['receiver'])) {
            $errors[] = "Please enter a valid eMail Address";
        } else if(strlen($_POST['receiver']) > 347) {
            $errors[] = "Your email is too long. Please provide a valid email address";
        } else if(filter_var($_POST['receiver'], FILTER_VALIDATE_EMAIL) === false) {
            $errors[] = "Please provide a valid eMail address";
        }else{
            $to = "<" .htmlentities($_POST['receiver']). ">";
        }

    //Validate the Message
        if(empty($_POST['body'])) {
            $errors[] = "Please enter a message.";
        } else {
            $body = htmlentities($_POST['body']);
        }
        }

?>

去掉里面()的($email)mail($to, $subject, $body, "From: ($email)");

读作：

mail($to, $subject, $body, "From: $email");

它现在可以工作了。（已测试）

当我最初使用()around对其进行测试时$email，它最终在 Spam 中使用unknown sender.

然后，当我删除括号时，它现在与发件人的电子邮件地址一起进入我的收件箱。
