使用 XMLHttpRequest 的 AJAX 请求返回 PHP 文件的内容而不是执行它

Question

I want to execute a PHP script on a Linux server running node.js by using a call to XMLHttpRequest on the client. Instead of executing the PHP script on the server, the script contents are returned. Is there a node.js configuration change required for the PHP script to be executed on the server? Also, since node.js is used for server side javascript, can I execute a javascript file, instead of a PHP file using XMLHttpRequest?

The goal is just to execute the script on the server just to do a simple task. At this time, I don't need anything returned to the client.

Client Side:

var xmlhttp;
if (window.XMLHttpRequest){// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
    if (xmlhttp.readyState==4 && xmlhttp.status==200)
    {
        document.getElementById("mailDiv").innerHTML=xmlhttp.responseText;
    }
}
xmlhttp.open("GET","phpfile.php",true);
xmlhttp.send();

Server side - PHP script phpfile.php

<?php
$to = "first.last@company.com";
$subject = "Hi!";
$body = "Hi,\n\nHow are you?";
if (mail($to, $subject, $body)) {
    echo("<p>Email successfully sent!</p>");
} else {
    echo("<p>Email delivery failed…</p>");
}
?>

Node.js and PHP are entirely different beasts. By default, node cannot execute PHP and will simply send the contents of the file to the client.

You can try something like node-php-server to execute PHP within node, but I think that your best bet is to just install Apache or nginx and use it to execute PHP.
