cURL返回“找不到对象！”

I'm having problem with cURL, it's returning no result or "Object not found!"

I know the site actually provide their own API, but i need more information to be grabbed. How to solve this problem ?

here's the code

<?php
        $URL = "http://myanimelist.net/manga.php?q=nisekoi";
        //Initl curl
        function get_web_page( $url )
        {
            $options = array(
                CURLOPT_RETURNTRANSFER => true,     // return web page
                CURLOPT_HEADER         => false,    // don't return headers
                CURLOPT_FOLLOWLOCATION => true,     // follow redirects
                CURLOPT_ENCODING       => "",       // handle all encodings
                CURLOPT_USERAGENT      => "spider", // who am i
                CURLOPT_AUTOREFERER    => true,     // set referer on redirect
                CURLOPT_CONNECTTIMEOUT => 120,      // timeout on connect
                CURLOPT_TIMEOUT        => 120,      // timeout on response
                CURLOPT_MAXREDIRS      => 10,       // stop after 10 redirects
            );

            $ch      = curl_init( $url );
            curl_setopt_array( $ch, $options );
            $content = curl_exec( $ch );
            $err     = curl_errno( $ch );
            $errmsg  = curl_error( $ch );
            $header  = curl_getinfo( $ch );
            curl_close( $ch );

            $header['errno']   = $err;
            $header['errmsg']  = $errmsg;
            $header['content'] = $content;
            return $header;
        }
            echo get_web_page($URL)['content'];
?>
