如何在php表单中在IP地址之前添加链接地址

我试图发布用户IP地址与跟踪IP位置的链接，我有下面的php代码。我想在这个

http://whatismyipaddress.com/ip/108.44.33.225

<?php 
if(isset($_POST['submit'])){
    $to = "email@example.com";
    $from = $_POST['email'];
    $first_name = $_POST['first_name'];
    $last_name = $_POST['last_name'];
    $ip=$_SERVER['REMOTE_ADDR'];
    $subject = "Email IP submission as link";
    $message = $first_name . " " . $last_name . " wrote the following:" . "\n\n" . $_POST['message'];
    $message .= "IP Address:" <a href="http://whatismyipaddress.com/ip/. $ip .">. $ip</a>";

    $headers = "From:" . $from;
    mail($to,$subject,$message,$headers);
    echo "Mail Sent. Thank you ";
    }
?>

您的代码存在连接问题，请尝试以下操作

$message .= "IP Address: <a href='http://whatismyipaddress.com/ip/".$ip."'>$ip</a>";

$message.=“IP地址：”；

而不是

$message .= "IP Address:" <a href="http://whatismyipaddress.com/ip/. $ip .">. $ip</a>";

$message.=“IP地址：”；
请更正此行：

$message .= "IP Address: <a href='http://whatismyipaddress.com/ip/". $ip ."'>". $ip."</a>";

$message.=“IP地址：”；

或者你可以试试

$message .= "IP Address: <a href='http://whatismyipaddress.com/ip/$ip'>$ip</a>";

$message.=“IP地址：”；
谢谢，但link不附带ip。我只得到“>这样的链接。任何解决方案，谢谢。谢谢你的时间。
