Simple Exec Insert

[Xcellz]

the issue is I think I've done something wrong, I just don't know what. I've tried try/catch, every other part of this code functions properly (I've echoed everything), but nothing is be inserted into "text". I'm 99% sure it isn't privileges, also as a general question is it ok to use exec when you're just shooting around data in your server and from other urls? Hope to get some replies.\[code\]<?phpinclude('simplehtmldom_1_5/simple_html_dom.php'); $html = new simple_html_dom(); $html->load_file('http://www.youtube.com/live/all/videos?sort=dd&tag_id=&view=41');$count = 0;$pdo = new PDO('mysql:host=localhost;dbname=scraper', 'user', 'aa');$string = $pdo->query('SELECT text FROM urls');while ($row = $string->fetch()){ $links[] = $row['text'];}foreach($html->find('[class=content-item-title yt-ui-ellipsis yt-ui-ellipsis-2]') as $element){$array[$count]=$element->href;foreach ($links as $link){if (strpos($array[$count], $link) == false){$pdo->exec('INSERT INTO urls SETtext=$array[$count]');}}$count += 1;}?>\[/code\]
