file_get_html() not working for the only webpage - simple-html-dom

Question

I want to call a simple DOM file
I tested with another links and it works, but with this url it's not working.
My code is:
$bnadatos = file_get_html("http://www.rofex.com.ar/cem/FyO.aspx");
foreach($bnadatos->find('[#id="ctl00_ContentPlaceHolder1_gvFyO"]') as $i){
echo "datos:";
echo $i->innertext;
}
Response is a blank page.
What's wrong?

Answer 1

i solved with
$arrContextOptions=array(
"ssl"=>array(
"verify_peer"=>false,
"verify_peer_name"=>false,
),
);
$response = file_get_html("https://www.rofex.com.ar/cem/FyO.aspx", false, stream_context_create($arrContextOptions));
foreach($response->find('[#id="ctl00_gvwDDF"]/tbody/tr[2]/td[2]') as $i){
echo $i->innertext;
}
thank you #maio290 for light my road

This is just a guess, but do you have your error reporting on?
Out of the box, this is not working with the simple-html-dom library:
Warning: file_get_contents(): SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed in /var/www/html/dom.php on line 83
Warning: file_get_contents(): Failed to enable crypto in /var/www/html/dom.php on line 83
Warning: file_get_contents(http://www.rofex.com.ar/cem/FyO.aspx): failed to open stream: operation failed in /var/www/html/dom.php on line 83
Fatal error: Call to a member function find() on boolean in /var/www/html/test.php on line 11
A fix for this can be found here - with that in place, I still get a blank page, which is due to a wrong answer (301 Moved Permanently) - for this to fix, you need to modify
'follow_location' => false
to
'follow_location' => true
so, now we get the proper site content - you can modify the selector to $html->find('#ctl00_ContentPlaceHolder1_gvFyO'); this will find all element which id=ctl00_ContentPlaceHolder1_gvFyO - see the documentation as reference.
