php - how to extract specific span content from webpage -

i looking scrape content of webpages.

i have following code not work on every page.

$url1 = 'http://www.just-eat.co.uk/restaurants-tomyumgoong/menu'; $url2 = 'http://www.just-eat.co.uk/';  $curl = curl_init($url1); curl_setopt($curl, curlopt_returntransfer, true);  $page = curl_exec($curl);  if (curl_errno($curl)) // check execution errors {   echo 'scraper error: ' . curl_error($curl);   exit; } echo $page; curl_close($curl);  $regex = '/<div class="responsive-header-logo">(.*?)<\/div>/s'; if (preg_match($regex, $page, $list))   echo $list[0]; else    print "not found";  

$url1 not working, when use $url2 works charm.

what can fix this?

try simplifying regex just:

$regex = '/responsive-header-logo/';
