foreach導致數組中，我怎麼能得到元素的值而不是數組？

我是一個不熟練的PHP用戶試圖生成一個XML RSS文檔，
使用PHP類RSS_PHP RSS Parser foreach導致數組中，我怎麼能得到元素的值而不是數組？

的foreach收益30 <items>這是很好的，因爲這是這是項目的XML源上的數字，但是當試圖讓<title>結果這是一個Array

我不知道我失蹤或者我需要改變爲從source而不是數組得到<title>的價值是什麼價值。

任何幫助將不勝感激，謝謝。

    $rss->load('http://digg.com/rss/index.xml');

    $html = ''; 
 
    foreach($items as $index => $item) { 
 
     $html .= '<p><a href="'.$item['link'].'" title="'.$item['title'].'"><strong>'.$item['title'].'</strong></a><br />

那麼，哪裏'title'從何而來？ –

在創建它之後不會附加到根元素 – charlietfl

@charlietfl謝謝..很抱歉，請問您，請給我更多關於如何附加到根文檔的信息？謝謝。 – Peter

你明白與$item變量發生在你foreach？

foreach($items as $index => $item) {   
    // here $item in a item of RSS feed 
    $item = $xml->addChild('item'); //add item node 
    // and here $item is an XML-node 
    // and as it is an XML-node now - 
    // it doesn't have `title` or `description` property 
    $title = $item->addChild('title', ''.['title'].''); //add title node  
    $description = $item->addChild('description', ''. ['description'] . ''); //add description 
}

正確代碼：

foreach($items as $index => $item) {   
    $xml_item = $xml->addChild('item'); //add item node 
    $title = $xml_item->addChild('title', ''.$item['title'].''); 
    $description = $xml_item->addChild('description', ''. $item['description'] . ''); 
}

非常感謝你的幫助，解釋和解決方案的代碼，它的工作原理，你不知道你有多少幫助我，謝謝！ – Peter

例如來自RSS parser的示例，每個$item是具有諸如title和description之類的關鍵字的關聯陣列。 ['title']是一個數組常量，其中包含一個字符串，'title'，如果你要訪問的標題項，你可以使用$item['title']給你這樣的：

$title = $item->addChild('title', $item['title']); //add title node

非常感謝@mzulch我替換了 '$ title = $ item- > addChild（'title'，''。['title']。''）; //添加標題節點' '$ title = $ item-> addChild（'title'，$ item ['title']）; //添加標題節點' 該數組已刪除，但結果爲空'' 您可以在我的網站上看到它：[link] http://zstreambox.com/mkttools/rssphp/t1.php [link ] – Peter

foreach導致數組中，我怎麼能得到元素的值而不是數組？
