用PHP验证电子邮件？

我正在尝试进行邮件验证，但它不起作用。这里有一些文本将给出一条成功消息或错误消息。但它没有显示任何内容。我不明白我的错。请帮助他人。

只需使用PHP手册中的默认函数：

     <?php
          if (isset($_POST["sendMessage"])) {
          $firstName = $_POST['firstName'];
          $lastName = $_POST['last-name'];
          $email = $_POST['email'];
          $phone = $_POST['phone'];
          $message = $_POST['message'];
          $from= 'info@address.com';
          $to = 'some@gmail.com';
          $subject = 'Message from Contact Demo ';
          $txt= 'demo';
          $headers = "From: webmaster@example.com" . "\r\n" .
         "CC: somebodyelse@example.com";
        $body = "From: First-Name: $firstName\n Last-Name: $lastName\n                    

        E-Mail: $email\n Phone: $phone\n Message: $message";
                        $errFirstName='';$errLastName='';$errEmail='';$errPhone='';$errMessage='';



// If there are no errors, send the email

        if (mail ($to, $subject,$txt,$headers)) {
            $result='<div class="alert alert-success">Thank You! I will be in touch</div>';
        } else {
            $result='<div class="alert alert-danger">Sorry there was an error sending your message. Please try again later</div>';
        }
    }

?>

首先，您必须使用此Php函数检查电子邮件是否有效

<?php
    $email_a = 'joe@example.com';
    $email_b = 'bogus';

    if (filter_var($email_a, FILTER_VALIDATE_EMAIL)) {
        echo "This ($email_a) email address is considered valid.\n";
    }
    if (filter_var($email_b, FILTER_VALIDATE_EMAIL)) {
        echo "This ($email_b) email address is considered valid.\n";
    } else {
   echo "This ($email_b) email address is considered invalid.\n";
   }
?>

如果无效，则给出一个错误 否则

if（邮件（$to、$subject、$txt、$headers））{
$result='谢谢！我会与您联系'；
}否则{
$result='抱歉，发送邮件时出错。请稍后再试'；
}

试试看..

在您的实时服务器上试试这段代码

if (mail ($to, $subject,$txt,$headers)) {
            $result='<div class="alert alert-success">Thank You! I will be in touch</div>';
        } else {
            $result='<div class="alert alert-danger">Sorry there was an error sending your message. Please try again later</div>';
        }

$firstName=“sunny”；
$lastName=“khatri”；
$email='******@gmail.com'；
$phone='********'；
$message='您好，这是测试'；
$from='******@gmail.com'；
$to='***@gmail.com'；
$subject='联系人演示信息'；
$txt='demo'；
$headers=“From:******@********.com”。“\r\n”。
“抄送：******@live.in”；
$body=“From:First Name:$firstName\n Last Name:$lastName\n
电子邮件：$email\n Phone:$Phone\n Message:$Message”；
$errFirstName=''$errLastName=''$errEmail=''$errPhone=''$errMessage=''；
//如果没有错误，请发送电子邮件
if（邮件（$to、$subject、$txt、$headers））{
$result='谢谢！我会与您联系'；
}否则{
$result='抱歉，发送邮件时出错。请稍后再试'；
}
回声$结果；

我在这里没有看到任何邮件验证代码？如果有，您可以指定结果或错误吗？您是德国人吗？你应该用谷歌搜索“will”这个词在英语中的意思。除此之外，尽量保持变量名的恒定性<代码>姓氏和

姓氏

——这是一种糟糕的做法。此外，可能会编辑您的问题，删除您的电子邮件地址，并替换为一些随机的东西。。。不要认为把你的电子邮件地址张贴在公共公告板上是个好主意。另外，通过“$errFirstName=”，您想要实现什么$errLastName=“”；`那么..@AlivetoDie认为他指的是最后的

if-else

条件-如果消息已发送，则验证…@Twinfriends谢谢你的建议。

if (mail ($to, $subject,$txt,$headers)) {
            $result='<div class="alert alert-success">Thank You! I will be in touch</div>';
        } else {
            $result='<div class="alert alert-danger">Sorry there was an error sending your message. Please try again later</div>';
        }

    $firstName = "sunny";
    $lastName = "khatri";
    $email = '******@gmail.com';
    $phone = '********';
    $message ='Hello this is test';
    $from= '*****@gmail.com';
    $to = '***@gmail.com';
    $subject = 'Message from Contact Demo ';
    $txt= 'demo';
    $headers = "From: ******@*****.com" . "\r\n" .
    "CC: ********@live.in";
    $body = "From: First-Name: $firstName\n Last-Name: $lastName\n                    

    E-Mail: $email\n Phone: $phone\n Message: $message";
                $errFirstName='';$errLastName='';$errEmail='';$errPhone='';$errMessage='';

    // If there are no errors, send the email

    if (mail ($to, $subject,$txt,$headers)) {
          $result='<div class="alert alert-success">Thank You! I will be in touch</div>';
    } else {
         $result='<div class="alert alert-danger">Sorry there was an error sending your message. Please try again later</div>';
    }
    echo $result;
