Question

在我的代码中，当我将Regexp内容分配给变量但不使用html时，我的url path工作正常。我得到空阵列。

    <?php 
    $productmfgno = "154637401";
                $url = "http://www.pandorasoem.com/search#q=".$productmfgno;
                $ch1= curl_init();
                curl_setopt ($ch1, CURLOPT_URL, $url );
                curl_setopt($ch1, CURLOPT_HEADER, 0);
                curl_setopt($ch1,CURLOPT_VERBOSE,1);
                curl_setopt($ch1, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.0.3705; .NET CLR 1.1.4322; Media Center PC 4.0)');
                curl_setopt ($ch1, CURLOPT_REFERER,'http://www.google.com');  //just a fake referer
                curl_setopt($ch1, CURLOPT_RETURNTRANSFER, 1);
                curl_setopt($ch1,CURLOPT_POST,0);
                curl_setopt($ch1, CURLOPT_FOLLOWLOCATION, 20);
                $htmlContent= curl_exec($ch1);
                curl_close($ch1);
      /* It works when I assign this html content to $htmlContent variable but not working with cURL url

  $htmlContent = '<div class="findify-navigation-header findify-clearfix"> <div class="findify-pagination findify-push-right"></div> <div class="findify-header">Showing 2 results for <span class="findify-query">"154637401"</span>. <span id="findify-didyoumean"></span></div> </div>';

*/
                preg_match_all('/<div.*class=\"findify\-header\".*?>(.*?)<span.*class=\"findify-query\">.*?<\/div>/Us', $htmlContent, $count);
                print_r($count);

预期结果 - Showing 2 results for

所以我可以获取结果计数。

事情是，页面上没有结果，您正在请求。加载页面后，通过ajax执行实际搜索。

搜索的Ajax端点，您可能正在寻找，在javascript代码中返回结果（而不是json）。那是：

http://api.findify.io/v1.0/store/search?callback=jQuery111206735094679573879_1458022087824&q=154637401&key=5b31ee91-78fa-48e1-9338-1748ca55028e&analytics%5Bkey%5D=5b31ee91-78fa-48e1-9338-1748ca55028e&analytics%5Bvisit%5D=true&analytics%5Buniq%5D=true&analytics%5Burl%5D=http%253A%252F%252Fwww.pandorasoem.com%252Fsearch%2523q%253D154637401&analytics%5Bbaseurl%5D=http%253A%252F%252Fwww.pandorasoem.com%252Fsearch%2523q%253D154637401&analytics%5Bhost%5D=www.pandorasoem.com&analytics%5Bwidth%5D=1920&analytics%5Bheight%5D=1200&analytics%5Binner_width%5D=1438&analytics%5Binner_height%5D=667&analytics%5Bdoc_width%5D=1438&analytics%5Bdoc_height%5D=915&analytics%5Bscroll_x%5D=0&analytics%5Bscroll_y%5D=0&analytics%5Bvisit_id%5D=Ts22zuHHGJRZc3U1&analytics%5Buniq_id%5D=BoeCUKSzgdML6C50&byPage=24&page=0&_=1458022087825

UPD ：由于格式不同，您需要一个新的正则表达式。这样的事情会做：

preg_match_all('/["\']?totalHits["\']?\s*:\s*(\d+)/gi', $htmlContent, $count);

Regexp不使用cURL url内容
