解析RSS訂閱用SimpleXML

Question

當我運行這段代碼：

<?php 
$rss = simplexml_load_file('http://stackoverflow.com/feeds'); 
?> 
<h1><?php echo $rss->title; ?></h1> 
<ul> 
<?php 
foreach($rss->entry as $e) { 
    echo "<li><a href=\"".$e->link['href']."\">"; 
    echo $e->title;  
    echo "</a></li>\n"; 
}  
?> 
</ul> 

它產生以下錯誤：

Warning: simplexml_load_file(http://stackoverflow.com/feeds) [function.simplexml-load-file]: failed to open stream: Permission denied in /home/www/cheapflightshunt.co.uk/aaaa.php on line 2 

Warning: simplexml_load_file() [function.simplexml-load-file]: I/O warning : failed to load external entity "http://stackoverflow.com/feeds" in /home/www/cheapflightshunt.co.uk/aaaa.php on line 2 

Warning: Invalid argument supplied for foreach() in /home/www/cheapflightshunt.co.uk/aaaa.php on line 7 

我的共享主機與PHP5.2.17運行

請提供解決方案。

在此先感謝。

您的代碼完美無缺。我懷疑你目前的設置不是allow fopen over url

試着檢查一下。

如果你不能改變的設置，儘量捲曲，而是：

<?php 
$ch = curl_init('http://stackoverflow.com/feeds'); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
$data = curl_exec($ch); 
curl_close($ch); 
$rss = new SimpleXMLElement($data); 
?> 
<h1><?php echo $rss->title; ?></h1> 
<ul> 
<?php 
foreach($rss->entry as $e) { 
    echo "<li><a href=\"".$e->link['href']."\">"; 
    echo $e->title;  
    echo "</a></li>\n"; 
}  
?> 
</ul>
