正則表達式不能使用cURL url內容

Question

在我的代碼中，當我將html內容分配給變量但不與url path一起使用時，我的Regexp正常工作。我得到空陣列。

<?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); 

預期結果 - Showing 2 results for

這樣我就可以獲取該結果計數。

事情是，頁面上沒有任何結果，您正在請求。加載頁面後，通過ajax進行實際搜索。

用於搜索的Ajax終結點，您可能正在尋找，返回的結果是javascript代碼（而不是json）。在那裏，它是：

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：由於格式是不同的，你需要一個新的正則表達式。這樣的事情會這樣做：

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