忘记在php中发送邮件的密码

这是我忘记的密码。。当我测试它时，它工作得很好。它将新密码添加到数据库中。但它不会向用户发送新密码邮件

<?php
   function generateRandomString($length = 15) {
    $characters = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
    $charactersLength = strlen($characters);
    $randomString = '';
    for ($i = 0; $i < $length; $i++) {
        $randomString .= $characters[rand(0, $charactersLength - 1)];
    }
    return $randomString;
}

include 'config.php';

$check=mysqli_num_rows(mysqli_query($conn,"SELECT * FROM users WHERE email='".$_POST['email']."'"));

        if($check==1)
        {
            $users=mysqli_fetch_assoc(mysqli_query($conn,"SELECT * FROM users WHERE email='".$_POST['email']."'"));
            $code=generateRandomString();
            $msg='Hy, '.$users['name'].' Your New Generated Password is: '.$code.'';
            $headers = "[Reset Password]";
            $mml($_POST['email'],'Reset Password',$msg,$headers);

            if($mml){
mysqli_query($conn,"UPDATE users SET password='".md5($code)."' where email='".$_POST['email']."'");

            echo '<div class="alert alert-success">
                      <strong>New Password Has Been Sent to Your Mail!</strong> Check Your Inbox.
                    </div>';} else {
echo '<div class="alert alert-warning">
                      <strong>Timeout, Try again later!</strong>.
                    </div>';
}

        } else {
                echo '<div class="alert alert-danger">
                              <strong>User not found!</strong>.
                            </div>';
        }
?>

有人能帮我解决这个问题吗？这将非常有帮助


好的，你有很多问题。正如注释所示，您目前根本没有调用实际的mail（）函数

mail（）函数接受许多参数，如果构造不正确，实际传递的邮件可能会有很多问题

这一行：

 $mnl = mail($_POST['email'],'Reset Password',$msg,$headers);

应该是：

    $hostname       = "yourhostname.org";
    $date           = date('r', time());
    $nameto         = "Mr. Target";
    $recipient      = "target@targetdomain.com";
    $from           = "origin_address@yourdomain.net";
    $namefrom       = "Mr. Sender";
    $subject        = "Password Reset Thingy";

    $headers = [];
    $headers[] = "MIME-Version: 1.0";
    //  $headers[] = "Content-type: text/plain; charset=iso-8859-1";
    $headers[] = "Content-type: text/html; charset=utf-8";
    $headers[] = "From: $namefrom <$from>";
    $headers[] = "Sender: $namefrom <$from>";
    //  $headers[] = "Bcc: Some Other Dude <me@mydomain.net>";
    $headers[] = "Reply-To: $namefrom <$from>";
    $headers[] = "To: $nameto <$recipient>";
    $headers[] = "Subject: $subject";
    $headers[] = "Message-ID: <". sha1(microtime(true)) ."@$hostname>"; //This is essential for getting to Gmail addresses.... 
    $headers[] = "X-Mailer: PHP/".phpversion();
    $headers[] = "Date: $date";
    $headers = implode("\r\n", $headers);

    $mnl = mail($recipient,$subject,$body,$headers,"-f $from") ;

这意味着如果函数成功，您将得到一个布尔值true/false。（这并不一定意味着你的邮件将到达它需要到达的地方…）为了确保你的邮件确实到达它想要到达的地方，你需要确保你的邮件头都正确构造，并且在此基础上正确配置你的DNS记录（DKIM、SPF等）

考虑以下代码段：

    function authSendEmail($from, $namefrom, $to, $nameto, $subject, $headers, $message) {


$smtpServer = "mail.yourhostname.com";
$port = "25"; //Or whatever the default port on your server is
$timeout = "30";
$username = "origin@yourdomain.com";
$password = "myemailpassword";
$localhost = "yourhostname.com";
$newLine = "\r\n";
$date = date('r', time()); 


    //Connect to the host on the specified port
$smtpConnect = fsockopen($smtpServer, $port, $errno, $errstr, $timeout);
$smtpResponse = fgets($smtpConnect, 515);
if(empty($smtpConnect)) {
    $output = "Failed to connect: $smtpResponse";
    return $output;
} else {
    $logArray['connection'] = "Connected: $smtpResponse";
}

   //Request Auth Login
fputs($smtpConnect,"AUTH LOGIN" . $newLine);
$smtpResponse = fgets($smtpConnect, 515);
$logArray['authrequest'] = "$smtpResponse";

    //Send username
fputs($smtpConnect, base64_encode($username) . $newLine);
$smtpResponse = fgets($smtpConnect, 515);
$logArray['authusername'] = "$smtpResponse";

    //Send password
fputs($smtpConnect, base64_encode($password) . $newLine);
$smtpResponse = fgets($smtpConnect, 515);
$logArray['authpassword'] = "$smtpResponse";

    //Say Hello to SMTP
fputs($smtpConnect, "HELO $localhost" . $newLine);
$smtpResponse = fgets($smtpConnect, 515);
$logArray['heloresponse'] = "$smtpResponse";

    //Email From
fputs($smtpConnect, "MAIL FROM: $from" . $newLine);
$smtpResponse = fgets($smtpConnect, 515);
$logArray['mailfromresponse'] = "$smtpResponse";

    //Email To
fputs($smtpConnect, "RCPT TO: $to" . $newLine);
$smtpResponse = fgets($smtpConnect, 515);
$logArray['mailtoresponse'] = "$smtpResponse";

    //The Email
fputs($smtpConnect, "DATA" . $newLine);
$smtpResponse = fgets($smtpConnect, 515);
$logArray['data1response'] = "$smtpResponse";

fputs($smtpConnect, "To: $to\nFrom: $from\nSubject: $subject\n$headers\n\n$message\n.\n");
$smtpResponse = fgets($smtpConnect, 515);
$logArray['data2response'] = "$smtpResponse";

     // Say Bye to SMTP
fputs($smtpConnect,"QUIT" . $newLine);
$smtpResponse = fgets($smtpConnect, 515);
$logArray['quitresponse'] = "$smtpResponse";

//Show log
//  echo "<pre>$to<br/>";
//  print_r ($logArray);
//  echo "</pre><hr />";
    $output = $logArray;
    return $output;
}   

希望这有助于你在某些方面的形状或形式
 我没有看到
mail（）
函数。我看到您试图将
$mml
用作邮件功能，但我没有看到定义任何
$mml
。如果您能帮助我进行更改，那将非常有用。。该模板附带了
$mml
。@WEBFOX，您只需使用适当的参数调用
mail（）
。@AlexBarker我对编码是新手，我刚刚开始学习。你能确定并更改应该更改的代码吗？这将非常有帮助。我尝试了各种可能的论点，比如邮件和一些来自网络的东西。但它会更改数据库中的密码，但不会发送邮件。@WEBFOX，在新密码发送到您的邮件之前的某个地方
调用内置函数。它只需要3个必要的参数：发送到的电子邮件，所述电子邮件的主题和正文。我真的很抱歉浪费你的时间，我使用了你的代码并修改了一些，但现在数据库没有得到新密码的更新，邮件也没有移动到用户。我可以给你发送重置php文件吗？你可以编辑吗。比如，在这里输入-，改变这个-。这将非常有帮助。我这样做了两天，找不到解决办法。是的，伙计，说吧。我不会真的为你们这么做，但我会写几点给你们，你们可以去读我所说的，然后自己改变它
