function ara($bas, $son, $yazi)
{
    @preg_match_all('/' . preg_quote($bas, '/') .
    '(.*?)'. preg_quote($son, '/').'/i', $yazi, $m);
    return @$m[1];
}



$site = "https://www.flickr.com/search/groups/?text=photos&sort=most-members";
$icerik = file_get_contents($site);
$getir = ara('class="click-anywhere no-outline">', '</td>', $icerik);
 echo $getir[0]; 

?>
