无法使用php5 domdocument加载网页内容

<?php
    class parsedictionary {
        public function _process() {
            $webpage="http://www.oppapers.com/essays/Computerized-World/160871?read_essay";
            $doc=new DOMDocument();
            $doc->loadHTML($webpage);
            echo $doc;
        }
    }
    $obj=new parsedictionary();
    $obj->_process();
?>

I can't get the content of that page.

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
<html>
    <body>
        <p>http://www.oppapers.com/essays/Computerized-World/160871?read_essay</p>
    </body>
</html>

But i need to get the content of that page.

    The DOMDocument class is obviously not a string; you can iterate it, perform operations on it, but it can't just be echoed. Check the documentation to see what you can do with it: http://www.php.net/domdocument

    To get the page contents, you can either use file_get_contents or do echo $doc->saveHTML()

    Edit: Didn't realize you had another problem in your code; you can just use this instead:

    public function _process() {
        return file_get_contents('http://www.oppapers.com/essays/Computerized-World/160871?read_essay');
    }
