html dom在它们存在时不会给出结果

Question

I am trying to get title of the webpage, see the code below..

include("simple_html_dom.php");
$url = "http://fzmoviez.in/video/list/4059539";

$base = $url;

$curl = curl_init();
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($curl, CURLOPT_URL, $base);
curl_setopt($curl, CURLOPT_REFERER, $base);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
$str = curl_exec($curl);
curl_close($curl);

// Create a DOM object
$html_base = new simple_html_dom();
// Load HTML from a string
$html_base->load($str);
$title = $html_base->getElementsByTagName("title")->innertext; //line 21
echo $title;

I am getting error:

Notice: Trying to get property of non-object in C:\xampp\htdocs\... on line 21

but when I var_dump($html_base) I get

object(simple_html_dom)#1 (23) { ["root"]=> object(simple...
    ... card" ["attr"]=> array(2) { ["id"]=> string(5) "index" ["title"]=> string(179) "FzMoviez.iN - Free Download Latest Bollywood Movies,Hindi Dudded Movies,Hollywood Movies,Live Movies,WWE Shows,Mp4,HD Mp4,High Quality Mp4,Avi,Iphone,Android,Tablets And Many More" } ["children"]=> array(25) { [0]=> object(simple_html_dom_node)#55 (9) { ["nodetype"]=>......

meaning, it is an object, and title is there, why giving error

Notice: Trying to get property of non-object in C:\xampp\htdocs\.. on line 21

Answer 1

$html_base->getElementsByTagName("title")
Will return array of elements, you need to iterate through this array to get your data.
