Regexp not working with cURL url contents

Question

In my code my Regexp works fine when I assign html content to variable but not working with url path . I am getting empty array.

    <?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);

Expected Result - Showing 2 results for

So I can fetch that result count.

Thing is, there are no results on the page, you're requesting. Actual search is performed via ajax after the page is loaded.

Ajax endpoint for the search, you might be looking for, returns result in javascript code (not json). There it is:

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: As the format is different you'll need a new regular expression. Something like this will do:

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