This code has been working good for months. The output consisted of a few lines containing statistics for a given username. The website from which the html page is taken is not down, and the content of the page in file_get_html hasn't changed. All of a sudden (I checked and nobody modified it) it stopped working. Here's the relevant part:

[...]if ($FileAge > ($expiretime * 60) || 0 == filesize($cachename))
{
    include_once('simple_html_dom.php');
    $html = file_get_html('http://www.foo.com/search?what=user%3A'.YOUR_USER.'&search=Search');
    var_dump($html); //TEST
    $link = $html->find('.likeh4 lightGrey.', 0)->find('a', 0)->href;   // Get the last activity link
[...]

The error log says:

[02-Feb-2013 17:02:19 Europe/Berlin] PHP Fatal error:  Call to a member function find() on a non-object in /foo.php on line 22 (the line with $link).

var_dump($html) gives bool(false)

I have a similar script which parses an html page from another website. It stopped working as well.

[...]include_once('simple_html_dom.php');
$html = file_get_html('http://my.flightmemory.com/'.FLIGHTMEMORY_USER);
$chilometri_table = $html->find('table', 2);    [...]

I tried to save on my webserver one of those html pages and I don't get such error. Did my host disable some php function for security reasons? (actually, file_get_html comes from simple_html_dom and not from php native functions)

Any hints? Thanks

It is probably way too late but:
Simple_html_dom has a constant to check given html size - MAX_FILE_SIZE. by default it's 600KB. It's enough for most cases, but if your given html is bigger than that, it will fail and returns false and causes that fatal error.

If you try to get [href] I had same problem and fixed it. need valid it's a simple_html_dom_node

if(is_a($html->find('.likeh4 lightGrey. a', 0),'simple_html_dom_node' )
  $link = $html->find('.likeh4 lightGrey. a', 0)->href;

OR

foreach ( $$html->find('.likeh4 lightGrey. a') as $links ) {
 $link =$links->href;
}
