Question

这是我的代码：

    <?php 

require('phpQuery.php');

function download($url)
{
    $curl = curl_init();
    curl_setopt_array($curl, array
    (
        CURLOPT_URL => $url,
        CURLOPT_USERAGENT => 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/22.0.1207.1 Safari/537.1',
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_CONNECTTIMEOUT => 120,
        CURLOPT_FOLLOWLOCATION => true,
        CURLOPT_HEADER => false
    ));

    $data = curl_exec($curl);
    curl_close($curl);

    return $data;
}

$pagina1 = phpQuery::newDocument(download('http://google.com'));

$logosrc = pq('img#hplogo').attr('src');
echo $logosrc;


?>

错误：

致命错误：在第26行的C：\ xampp \ htdocs \ projects \ new \ extract.php中调用未定义的函数attr（）

谁知道问题出在哪里？

Answer 1

更改

$logosrc = pq('img#hplogo').attr('src');

要

$logosrc = pq('img#hplogo')->attr('src');

我想，但我没有测试过它。
