在本地主机上使用时，x-mailer邮件功能不起作用

Question

我将使用此代码发送简单邮件。但是执行条件的时间将是错误的。（其他部分）

    $fname=$_POST['form_name'];
    $email=$_POST['form_email'];
    $phone=$_POST['form_phone'];
    $subject=$_POST['form_subject'];
    $remarks=$_POST['form_message'];


   $message = "Hi you have a new Enquiry"."\r\n". "See Details below". "\r\n" . "Name :".$fname." "."\n". "Email :".$email. "\n"."Contact Number : ".$phone."\n"."Subject Number : ".$subject."\n"."remarks :".$remarks."\n";



        $subject='test message ' .$email;
        $message=$message;
        $headers= 'From: mail@test.in' . "\r\n" .'Reply-To: mail@test.in' . "\r\n" .'X-Mailer: PHP/' . phpversion();
        $headers.= 'MIME-Version: 1.0' . "\r\n";



          if(mail("test@gmail.com",$subject,$message,$headers)) {
             echo '<div class="text-center"> <p class="success" style="color: #d1287a; font-size: 26px;
            padding-top: 30px;">Thank you for  Registering  with us, We will Contact you Soon!   </p></div>';

        } else {
            echo 'Error while sending mail,Please try again later';
        }
 }
