Question

I am using this library (PHP Simple HTML DOM parser) to parse a link, here’s the code:

function getSemanticRelevantKeywords($keyword){
    $results = array();
    $html = file_get_html("http://www.semager.de/api/keyword.php?q=". urlencode($keyword) ."&lang=de&out=html&count=2&threshold=");
    foreach($html->find('span') as $e){
            $results[] = $e->plaintext;
    }
    return $results;
}

but I am getting this error when I output the results:

Fatal error: Call to a member function find() on a non-object in
/var/www/vhosts/efamous.de/subdomains/sandbox/httpdocs/getNewTrusts.php
on line 25

(line 25 is the foreach loop), the odd thing is that it outputs everything (at least seemingly) correctly but I still get that error and can’t figure out why.

Answer 1

This error usually means that $html isn’t an object.

It’s odd that you say this seems to work. What happens if you output $html?
I’d imagine that the url isn’t available and that $html is null.

Edit:
Looks like this may be an error in the parser. Someone has submitted a bug and added a check in his code as a workaround.
