如何为我网站的多个用户发送单个邮件？

Question

结果中显示的错误是

Warning: mail(): Failed to connect to mailserver at "localhost" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set() in C:\wamp\www\elvisstore\sendemail.php on line 17

sendmail.php文件是这样的：

<?php
$from = 'something@gmail.com';
$subject =$_POST['subject'];
$text =$_POST['elvismail'];
$dbc= mysqli_connect( 'localhost' , 'smile' ,'password','elvis_store') 
or die('error in connecting to database');

$query = "SELECT * FROM email_list";
$result = mysqli_query($dbc,$query) or die('error in querying data');
//$row = mysqli_fetch_array($result);
while($row=mysqli_fetch_array($result))
{
   $first_name = $row['first_name'];     
   $last_name = $row['last_name']; 
   $msg = "Dear $first_name $last_name, \n  $text" ;
   $to =$row['email']; 
   mail($to, $subject, $msg, 'FROM:' . $from);
   echo "Email sent to $to <br>";
}
  mysqli_close($dbc);
?>

sendemail.html文件

<form method="post" action="sendemail.php"> 

    <label for="subject">Subject of email:</label><br /> 
        <input type="text" id="subject" name="subject" size="60" /><br />     
        <label for="elvismail">Body of email:</label><br />     
        <textarea id="elvismail" name="elvismail" rows="8" cols="60"></textarea><br />     
        <input type="submit" name="submit" value="Submit" />   
    </form> 
</body> 

我认为这个错误是由于我使用localhost作为我的服务器。请告诉我发生了什么事？

Answer 1

您的本地主机上是否安装了任何邮件服务器，或者您是否尝试通过某些外部邮件服务器发送？

您需要将这段代码添加到php页面的顶部：

ini_set('SMTP','myserver');
ini_set('smtp_port',25);

替换“myserver”的地方使用您要使用的SMTP服务器的IP地址，以及使用给定服务器的正确端口。
