PHP Dom使用strpos获取某些href值

Question

Could someone please tell me why this ain't working.

I'm trying to get a certain href and from a page by using php dom and that href - www.imdb.com/title/tt-some-id contains the word imdb so in the example below i try to get the href by using php function strpos to look for the word imdb but it don't seen to work.

$page = 'www.someurl.com';
$data = array();
$dom = new DOMDocument();
@$dom->loadHTML($page);

$data['imdb_link'];

$links = $dom->getElementsByTagName('a');
foreach ($links as $link) {
    $href = $link->getAttribute('href');
    if (false !== strpos($href,'imdb')) {
        $data['imdb_link'] = $href;
    } else {
        $data['imdb_link'] = '';
    }
}

And the links from the page

<a href="some-url.com"></a>
<a href="www.imdb.com/title/some-id"></a>
<a href="another-url.com"></a>
<a href="another-url.com"></a>

Could someone please tell me why it ain't working thanks

Answer 1

That is actually working , but you are overwriting it..

As you can see your final <a> href does not contain the text imdb , so that will be overwritten by your previously found result by your else statement.

Well how to fix it ?

Just remove the else part from your code.
