Question

我正在尝试使用PHPQuery获取给定页面上包含特定url页面的所有链接。我正在使用PHPQuery的PHP支持语法。

include_once 'phpQuery.php';
$url = 'http://www.phonearena.com/phones/manufacturer/';
$doc = phpQuery::newDocumentFile($url);

$urls = $doc['a'];

foreach ($urls as $url) {
    echo pq($url)->attr('href') . '<br>';
}

上面的代码有效。但它显示了所有链接我想只显示包含＆＃34; / phones / manufacturer /＆＃34;的那些。我尝试了这个，但它没有显示任何内容：

include_once 'phpQuery.php';
$url = 'http://www.phonearena.com/phones/manufacturer/';
$doc = phpQuery::newDocumentFile($url);

$urls = $doc['a'];

foreach ($urls as $url) {
    echo pq($url)->attr('href:contains("/phones/manufacturer/")') . '<br>';
}

Answer 1

使用以下编码从该网站获取所有网址

        $doc = new DOMDocument();
                @$doc->loadHTML(file_get_contents('http://www.phonearena.com/phones/manufacturer/'));

                $ahreftags = $doc->getElementsByTagName('a');

                    foreach ($ahreftags as $tag) {
                        echo "<br/>";
                        echo $tag->getAttribute('href');
                        echo "<br/>";
                    }


exit;

试试这个，italian guide，jquery documentation

include_once 'phpQuery.php';
$url = 'http://www.phonearena.com/phones/manufacturer/';
