新人提问:这个问题也太诡异了吧。。关于RSS的基础应用

PHP code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/--><?php require_once('magpierss/rss_fetch.inc');        $url = "http://localhost/PHPProject/RSS/RSS.xml";    $rss = fetch_rss($url);        $feedTitle = $rss->channel['title'];    echo '<p>Latest News from <strong>' . $feedTitle . '</strong></p>';        foreach ($rss->item as $it) {        $link = $it['link'];        $title = $it['title'];        $description = isset($it['description']) ? $it['description'] : '';                echo '<p><a href="%5C%22%24link%5C%22">' . $title . '</a><br>' . $description . '</p>';    }?>

1.
为什么运行显示为:
Latest News from W3School Home Page

RSS Tutorial
New RSS tutorial on W3School

后点击RSS Tutorial后却显示HTTP 403?




2.
在PHP中的foreach ($rss->item as $it)中的item为什么非要设置items才可以运行成功,否则为
Latest News from W3School Home Page


Notice: Undefined property: MagpieRSS::$item in D:\Apache Group\Apache2\htdocs\PHPProject\index5.php on line 10

Warning: Invalid argument supplied for foreach() in D:\Apache Group\Apache2\htdocs\PHPProject\index5.php on line 10


但我的XML中之内是而非喔。。。。




3.
我修改XML文件之前的中的是“W3School Home Page”,所以运行时显示为Latest News from W3School Home Page;但修改后却如上所示<title>XHTML,为什么刷新后也显示Latest News from W3School Home Page?

就算重启整个zend studio都继续显示Latest News from W3School Home Page,真不明白。。。。也不关缓存的事啊。。我已经清除了缓存了


麻烦各位帮帮忙。。我还有分加的

------解决方案--------------------
1. 你的代码有问题:
echo '

' . $title . '
' . $description . '

';
由于 $link在单引号内所以不会被解析。所以链接也就是 本页链接$link
至于为什么403无权限就要看你的服务器设置。

2. RSS标准中规定: A channel may contain any number of s.
XML code
<channel>     ...     <item>...</item>     <item>...</item>     <!-- 可能有多个 --></channel><br><font color="#e78608">------解决方案--------------------</font><br>
探讨

引用:

你怎么修改的。下面这样呢:
echo "

$title
$description

";


这个不行吗??

echo '

' . $title . '
' . $description . '

';

不是说……

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
