Question

我正在关注有关RESTful Web服务（Creating a RESTful Web Service in PHP）的视频教程。在本教程中，我们可以通过URL传递书籍名称来检索价格。

以下是代码：

的index.php

<?php
    // Process client request VIA URL
    header("Content-Type:application/json");
    include("functions.php");
    if(!empty($_GET['name']))
    {
        // if we have the name of the book in our url
        $name=$_GET['name'];
        $price=get_price($name);

        if(empty($price))
            // Book not found
            deliver_response(200,"book not found", NULL);
        else
            // Response book price
            deliver_response(200,"book_found", $price);



    }
    else
    {
        // Throw invalid request
        deliver_response(400,"invalide request", NULL);
    }

    function deliver_response($status, $status_message, $data)
    {
        header("HTTP/1.1 $status $status_message");
        $response['status']=$status;
        $response['status_message']=$status_message;
        $response['data']=$data;

        $json_response=json_encode($response);
        echo $json_response;
    }

?>

FUNCTION.PHP

<?php
    function get_price($find)
    {
        $books=array
        (
            "java"=>299,
            "c"=>348,
            "php"=>267
        );
        foreach($books as $book=>$price)
        {
            if($book=$find)
            {
                return $price;
                break;
            }
        }
    }
?>

的.htaccess

# Turn on the rewrite engine
Options +FollowSymlinks
RewriteEngine on

# Request routing
RewriteRule ^([a-zA-Z_-]*)$ index.php?name=$1 [nc, qsa]

虽然我在没有.htaccess文件的情况下尝试教程，但它运行良好。但是当我把这个文件放到我的目录中时，它总是崩溃＆＃34; SERVER ERROR＆＃34;，出现500错误。

请你解释一下吗？

重写时htaccess错误500
