Question

I have this html:
<h2><a href="http://.... > title</h2>
How can I get the string “href”?

I tried with:

include('simple_html_dom.php');
$html = file_get_html('http://...');

foreach($html->find('h2')->find('a') as $k) {
echo $k->href . '<br>';
}

error: Call to a member function find() on a non-object

Answer 1

I have not used PHP Simple HTML DOM Parser…but I think the error could be because it returns you a string and you are applying the find function on that returned string which is expecting a html object to be passed…

The previous solution is wrong bcz it just searched for a string while find function searches a tag..

One possible way is what I have commented..
remove first ‘h2’ find creteria and apply for all ‘a’ that is

foreach($html->find('a') as $k) {
echo $k->href . '<br>';
}    

Other possible solution is use php inbuild file_get_contents and seach by regular
expressions…I have done that for you…

$html = file_get_contents('new.php');
$reg_exUrl = "/(http|https|ftp|ftps)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?/";
$uql=array();
preg_match($reg_exUrl, $html, $url);

print_r($url);
