我终于让我的刮刀工作了(有点),但现在我想知道如何自动转到下一页并从那里刮取相同的信息。我正在使用 cURL 复制整个页面(否则我会收到 500 错误)。这是我的代码:
<?
// create curl resource
        $ch = curl_init();
        // set url
        curl_setopt($ch, CURLOPT_URL, "http://example.com/results.asp?&j=t&page_no=1");
        //return the transfer as a string
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        // $output contains the output string
        $html = curl_exec($ch);
        // close curl resource to free up system resources
        curl_close($ch);      
// print $html . "\n";
require 'simple_html_dom.php';           
$dom = new simple_html_dom();
$dom->load($html);
foreach($dom->find("div[@id='schoolsearch'] tr") as $data){
    $tds = $data->find("td");
    if(count($tds)==3){
        $record = array(
            'school' => $tds[1]->plaintext, 
            'city' => $tds[2]->plaintext
        );
        print json_encode($record) . "\n";
        file_put_contents('schools.csv', json_encode($record) . "\n", FILE_APPEND);
    }
}
?>
它并不完美,但它现在有效!有谁知道我怎样才能转到下一页?
