Question

我正在使用DOM抓取HTML以从外部网站创建自定义RSS源。我在名为$jobs的数组中拥有所需的所有值。我可以打印这样的值：

function jobscrape($title, $link, $root, $description, $job_location) {

$jobs = array();

$html = file_get_contents($link);
$doc = new DOMDocument();
libxml_use_internal_errors(TRUE);

if(!empty($html)) {

    $doc->loadHTML($html);
    libxml_clear_errors(); // remove errors for yucky html
    $xpath = new DOMXPath($doc);

    $row = $xpath->query($job_location);

    if ($row->length > 0) {

        foreach ($row as $job) {

            $jobs['title'] = $job->nodeValue;
            $jobs['description'] = "This is a description";
            $jobs['link'] = $job->getAttribute('href');

        }
    }
    else { echo "row is less than 0";}
}

else { echo "this is empty";}
}
}

但是，我需要这种格式的数组，其中每个'子数组'是三个变量的一次迭代（我这里只使用三个作为例子）：

$entries = array(
    array(
        "title" => "My first test entry",
        "description" => "This is the first article's description",
        "link" => "http://leolabs.org/my-first-article-url"
    ),
    array(
        "title" => "My second test entry",
        "description" => "This is the second article's description",
        "link" => "http://leolabs.org/my-second-article-url"
    ),
    array(
        "title" => "My third test entry",
        "description" => "This is the third article's description",
        "link" => "http://leolabs.org/my-third-article-url"
    )
);

更新

在尝试Durgesh的解决方案后，这是我的新代码：

function jobscrape($title, $link, $root, $description, $job_location) {

header("Content-Type: application/rss+xml; charset=UTF-8");

$xml = new SimpleXMLElement('<rss/>');
$xml->addAttribute("version", "2.0");
$channel = $xml->addChild("channel");

$channel->addChild("title", $title);
$channel->addChild("link", $link);
$channel->addChild("description", "This is a description");
$channel->addChild("language", "en-us");

$html = file_get_contents($link);
$doc = new DOMDocument();
libxml_use_internal_errors(TRUE);

if(!empty($html)) {

    $doc->loadHTML($html);
    libxml_clear_errors(); // remove errors for yucky html
    $xpath = new DOMXPath($doc);

    $row = $xpath->query($job_location);

    if ($row->length > 0) {

        foreach ($row as $job) {

            $jobs = array();
            $entries = array();

            $jobs['title'] = $job->nodeValue;
            $jobs['description'] = "This is a description";
            $jobs['link'] = $job->getAttribute('href');

            array_push($entries,$jobs);

            foreach ($entries as $entry) {

                $item = $channel->addChild("item");
                $item->addChild("title", $entry['title']);
                $item->addChild("link", $entry['link']);
                $item->addChild("description", $entry['description']);

            }

            echo $xml->asXML();

        }
    }
    else { echo "row is less than 0";}
}

else {
    echo "this is empty";
}

}

但是，我的RSS格式不正确，将以下内容添加到每个<item>，而不是仅添加到标题中：

<?xml version="1.0"?>
<rss version="2.0"><channel><title>Media Muppet</title><link>http://www.mediargh.com/jobs</link><description>This is a description</description><language>en-us</language>

如果您的$jobs提供了正确的数组，则可以通过

创建$entries数组

array_push($entries,$jobs);

我如何以这种格式获得PHP数组？
