用PHP读取RSS内容,实现与BLOG的同步
网络整理 - 08-17
现在,几乎每一个博客都有自己的RSS聚合系统,针对RSS,以下这个小程序,实现了与BLOG的同步调用。
以下为引用的内容:
<meta content="text/html; charset=utf-8" http-equiv="Content-Type">// The file test.xml contains an XML document with a root element
// and at least an element /[root]/title.
$xmlfile = date('YmdH').'.xml';
$sourcexml = 'http://blog.eaxi.com/rss.xml';
//die($xmlfile);
if( !file_exists($xmlfile) ) {
echo '你是第一次访问本系统。正在初始化...';
$str = @file($sourcexml) or die('加载文件时出错。');
$str = join('',$str);
$fp = fopen($xmlfile,'w') or die('写缓存失败!');
fputs($fp,$str);
fclose($fp);
echo "初始化完毕。";
}
if (file_exists($xmlfile)) {
$xml = simplexml_load_file($xmlfile);
//print_r($xml);
$c = &$xml->channel;
echo '</meta>
</code></p>
<h2><a title="" href="'.$c->link.'">'.$c->title.'</a></h2>
<p>';
echo '</p>
<h5>'.$c->lastBuildDate.'</h5>
<hr />
<p>';
$listhead = '</p>
<table border="1">
<tbody>
<tr>
<td>序号</td>
<td>标题</td>
<td>作者</td>
<td>类别</td>
<td>评论</td>
<td>时间</td>
</tr>
';
echo $listhead;
$k = 0;
foreach($c->item as $v) {
$k ++;
echo "
<tr>
<td>$k</td>
<td><a title="$v->title" href="$v->link">$v->title</a></td>
<td>$v->author</td>
<td>$v->category</td>
<td><a title="点击发表评论" href="$v->comments">评论</a></td>
<td>$v->pubDate</td>
</tr>
";
}
echo '
</tbody>
</table>
<p>';
} else {
exit('Failed to open xml file.');
}
?>
