无法废弃使用GET请求处理数据的网站

Question

I am unable to scrape this website

Through browser, I am able to get only after I do a search and then I can navigate to any page.

Through code, I am unable to get data.

Below is my code:

    $url = "http://assessor.islandcountywa.gov/propertyaccess/SearchResults.aspx?cid=0&rtype=address&page=";
    for($i=1; $i<=1239 ; $i++)
    {
    $starturl = $url.$i;    
    echo "
 Scrpaing URL -> $starturl 
";
    $context = stream_context_create();
    stream_context_set_params($context, array('user_agent' => 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/59.0.3071.86 Safari/537.36'));
    $dom    = file_get_html($starturl, 0, $context);
    $rows   = $dom->find("table[id=propertySearchResults_resultsTable]/td/tr");
    echo "
 ** Rows is ***
".count($rows);

I am getting 0 rows, and the html page that is retrieved is that of this URL
