通过 simplehtmldom PHP 从谷歌学者个人资料中抓取出版物

Question

我正在尝试从谷歌学者个人资料中抓取出版物，但我不知道如何从个人资料中抓取每个出版物，我知道个人资料页面可以显示的最大出版物是每页 100 个来自这个问题：

Google Scholar profile scrape PHP

我只想知道如何将 url 应用到我的 php 代码中，以便我可以从配置文件中获取每个出版物并将它们插入到数组中

我可以使用以下代码将单个页面中的每个出版物放到一个数组中：

<?php 
set_time_limit(0);  
include 'simple_html_dom.php';

$data = json_decode(file_get_contents('php://input'),true);
$scholarID =  $data["gScholarID"];
$kodeDosen = $data["kodeDosen"];
$page = 1;
$offset = ($page - 1)* 100;
$cStart = 0+$offset;
$profile = 'https://scholar.google.com/citations?user='.$scholarID.'&hl=en&cstart='.$cStart.'&view_op=list_works&pagesize=100';
$html = file_get_html($profile);
$table = $html->find('#gsc_a_t',0);
$rowData = array();

foreach($table->find('tr.gsc_a_tr') as $row){
    $paperjudul  = $row->find('td.gsc_a_t a', 0)->plaintext;
    $paper['kodeDosen'] = $kodeDosen;
    $paper['judul'] = $paperjudul;
    $cited   = $row->find('td.gsc_a_c', 0)->plaintext;
    if($cited === ''){
        $cited = 0;
    }
    $cited = preg_replace('/[\*]+/', '', $cited);
    $paper['citedBy'] = $cited;
    $paper['namaJurnal']    = $row->find('td.gsc_a_t .gs_gray', 1)->plaintext;
    if($paper['namaJurnal'] === ''){
        $paper['namaJurnal'] = 'n/a';
    }
    $paper['periode']   = $row->find('td.gsc_a_y', 0)->plaintext;
    if($paper['periode'] === ' '){
        $paper['periode'] = 'n/a';
    }
    $paper['status'] = 'Published';
    $rowData[] = $paper;
}

print_r($rowData);


?>

我只是想知道如何将此代码应用于多个页面以从 google 学者个人资料中获取所有出版物

我找到了一种可行的方法，首先，我创建了一个循环来搜索网页以指示该页面没有要显示的出版物并插入包含出版物的 url，然后我循环以在网址。 这是我使用的代码：

<?php 
set_time_limit(0);  
include 'simple_html_dom.php';
include 'connectdb.php';

$scholarID =  $_GET["gScholarID"];
$kodeDosen = $_GET["kodeDosen"];

$page = 1;
$finalPage = false;

$sqlTest = 'INSERT INTO tbl_publikasi(kodeDosen,jenis,namaJurnal,judul,status,tipePublikasi,periode,tahun,citedCount) VALUES ';
$response = array();


while (!$finalPage) {
    $offset = ($page - 1)* 100;
    $cStart = 0+$offset;
    $profile = 'https://scholar.google.com/citations?user='.$scholarID.'&hl=en&cstart='.$cStart.'&view_op=list_works&pagesize=100';
    $html = file_get_html($profile);
    if(is_object($html)){
        $empty = $html->find('td.gsc_a_e',0);
        if($empty){
            $finalPage = true;
            unset($html);
        }
        else{
            $urlArray[] = $profile;
            $page++;
        }
    }
    else{
        $response['success'] = 0;
        $response['message'] = "URL tidak valid ";
    }

}

if($finalPage){
    foreach ($urlArray as $urlPublikasi) {
        $html = file_get_html($urlPublikasi);
        $table = $html->find('#gsc_a_t',0);
        $rowData = array();
        if($table){
            foreach($table->find('tr.gsc_a_tr') as $row){
                $paper['kodeDosen'] = $kodeDosen;
                $paperjudul  = $row->find('td.gsc_a_t a', 0)->plaintext;
                $paper['judul'] = $paperjudul;
                $cited   = $row->find('td.gsc_a_c', 0)->plaintext;
                if($cited === ''){
                    $cited = 0;
                }
                $cited = preg_replace('/[\*]+/', '', $cited);
                $paper['citedBy'] = trim($cited);
                $paper['jenis'] = 'Scholar';
                $paper['namaJurnal']    = $row->find('td.gsc_a_t .gs_gray', 1)->plaintext;
                if($paper['namaJurnal'] === ''){
                    $paper['namaJurnal'] = 'n/a';
                }
                $paper['periode'] = 'n/a';
                $paper['tahun']   = $row->find('td.gsc_a_y', 0)->plaintext;
                if($paper['tahun'] === ' '){
                    $paper['tahun'] = '0000';

                $paper['tipePublikasi'] = 'Scholar'; 
                $paper['status'] = 'Published';
                $rowData[] = $paper;
            }

            foreach ($rowData as $paperValue) {
                $judul = $paperValue['judul'];
                $jenis = $paperValue['jenis'];

     }
