PHP：在此服务器上找不到请求的URL /读取

作为php 新手，有人建议我一步一步地执行这个教程：http://symfony.com/doc/current/book/from_flat_php_to_symfony2.html它对于初学者来说简直太友好了，我还创建了我的第一个博客。但当我试图获取 “show”界页时，它会显示一个通过 id 查询参数识别的博客帖子，浏览器显示：

requested URL /read was not found on this server.' I don't use .htaccess and rewrite mode of apache (version of server - Apache/2.2.22) is enable.

代码如下：

Front Controller

<?php
// index.php

// load and initialize any global libraries
require_once 'model.php';
require_once 'controllers.php';

// route the request internally
$uri = $_SERVER['REQUEST_URI'];
if ('/index.php' == $uri) {
    list_action();
} elseif ('/index.php/show' == $uri && isset($_GET['id'])) {
    show_action($_GET['id']);
} else {
    header('Status: 404 Not Found');
    echo '<html><body><h1>Page Not Found</h1></body></html>';
}

Controllers.php

function list_action()
{
    $posts = get_all_posts();
    require 'templates/list.php';
}

function show_action($id)
{
    $post = get_post_by_id($id);
    require 'templates/show.php';
}

Model

<?php
// model.php
function open_database_connection()
{
    $link = mysql_connect('localhost', 'root', 'zoob');
    mysql_select_db('post', $link);

    return $link;
}

function close_database_connection($link)
{
    mysql_close($link);
}

function get_all_posts()
{
    $link = open_database_connection();

    $result = mysql_query('SELECT id, title FROM post', $link);
    $posts = array();
    while ($row = mysql_fetch_assoc($result)) {
        $posts[] = $row;
    }
    close_database_connection($link);

    return $posts;
}

function get_post_by_id($id)
{
    $link = open_database_connection();

    $id = intval($id);
    $query = 'SELECT date, title, post FROM post WHERE id = '.$id;
    $result = mysql_query($query);
    $row = mysql_fetch_assoc($result);

    close_database_connection($link);

    return $row;
}

Templates

//layout.php
<!DOCTYPE html>
<html>
<head>
    <title><?php echo $title ?></title>
</head>
<body>
<?php echo $content ?>
</body>
</html>

//list.php

<?php $title = 'List of Posts' ?>

<?php ob_start() ?>
<h1>List of Posts</h1>
<ul>
    <?php foreach ($posts as $post): ?>
        <li>
            <a href="/read?id=<?php echo $post['id'] ?>">
                <?php echo $post['title'] ?>
            </a>
        </li>
    <?php endforeach ?>
</ul>
<?php $content = ob_get_clean() ?>

<?php include 'layout.php' ?>

//show.php
<?php

$title = $post['title'] ?>

<?php ob_start() ?>
    <h1><?php echo $post['title'] ?></h1>

    <div class="date"><?php echo $post['date'] ?></div>
    <div class="body">
        <?php echo $post['body'] ?>
    </div>
<?php $content = ob_get_clean() ?>

<?php include 'layout.php' ?>

请帮我解决这个问题吧，谢谢！

You have a mismatch in your routes and how you refer to them.

In list.php you refer to /read?id=
In index.php you defined /show?id=

Change either of the two and you should be good to go.

Well, now that the controller actually gets the request, you just have to debug the URI and GET requests to make sure they match your requirements. Do something like that in your front controller :

<?php
// index.php

// load and initialize any global libraries
require_once 'model.php';
require_once 'controllers.php';

// route the request internally
$uri = $_SERVER['REQUEST_URI'];
if ('/index.php' == $uri) {
    list_action();
} elseif ('/index.php/show' == $uri && isset($_GET['id'])) {
    show_action($_GET['id']);
} else {
    header('Status: 404 Not Found');
    echo '<html><body><h1>Page Not Found</h1></body></html>';
    var_dump($uri);
    var_dump($_GET);
}
