【问题描述】：

我正在使用 xampp v3.2.1，

我想使用表单向任何电子邮件帐户（gmail、hotmail）发送消息。我如何使用下面的代码来做到这一点？

<?php 
    mail($to,$subject,$body,"From:{$email}");
?>

当我使用上述邮件功能发送电子邮件时我发现我的电子邮件作为“C:\xampp\mailoutput”目录中的文本文件；

这是我的代码..

<?php

    if(isset($_POST['submit'])){

    //validate subject
    if(empty($_POST['subject'])){
    $errors[]="Enter a Subject";
    }else{
    $subject =htmlentities($_POST['subject']);
    }

    //validate sender
    if(empty($_POST['sender'])){
    $errors[]="Enter your email Address";
    }elseif(strlen($_POST['sender'])>200){
    $errors[] = "provided email address is too long";
    }elseif(filter_var($_POST['sender'],FILTER_VALIDATE_EMAIL)===false){
    $errors[]= "Provide a valid Email address!";
    }else{
    $email = "<".htmlentities($_POST['sender']).">";
    }

    #validate receiver
    if(empty($_POST['receiver'])){
    $errors[] = "Enter a email Address";
    }elseif(strlen($_POST['receiver'])>200){
    $errors[] = "provided reciever's email address is too long";
    }elseif(filter_var($_POST['receiver'],FILTER_VALIDATE_EMAIL)===false){
    $errors[]= "Provide a valid Email address to reciever!";
    }else{
    $to ="<".htmlentities($_POST['receiver']).">";
    }
    //validate message
    if(empty($_POST['message'])){
    $errors[] = "Enter a Message";
    }else{
    $body = htmlentities($_POST['message']);
    }


}
?>



<!Doctype html>
<html>
<head>
</head>
<body>
<?php if(empty($errors)===false){ ?>

<ul>
    <?php 
        foreach($errors as $error){
        echo "<li>",$error,"</li>";
        }
    ?>
</ul>
<?php }else{
    if(isset($to, $subject, $body, $email)){ 
    mail($to,$subject,$body,"From:{$email}");
    echo "Message Sent!";}

}
?>
<h1>SENDING EMAIL TEST</h1>
<form action="index.php" method="post">

<tr>

// apply all the rest validation you used
        $to=$_POST['receiver'];

        $body=$_POST['message'];
        $from=$_POST['sender'];
