I try this (but its not works):

$html = file_get_html('http://www.google.com/');
$el=$html->find('meta[content]',0);
echo $el->charset; 

What should be change?
(I know that $el->charset not working)

Thanks

You’ll have to match the string using a regular expression (I hope you have PCRE…).

$el=$html->find('meta[http-equiv=Content-Type]',0)
$fullvalue = $el->content;
preg_match('/charset=(.+)/', $fullvalue, $matches);
echo $matches[1];

Not very robust, but should work.
