php采集 curl

使用curl采集，$url = 'http://kakaku.com/pc/';请问怎么修改下面的代码？

 function GetContent($url = "", $post_data = '', $method = 'POST', $timeout = 500) {
        if (is_array($post_data)) {
            $post_data = http_build_query($post_data);
        }
        if ($method == 'GET') {
            $url = $url . '?' . ltrim($post_data, '?');
        }
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_HTTPHEADER, array('User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US) \r\n Accept: */*'));
        curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        if ($method == 'POST') {
            curl_setopt($ch, CURLOPT_POST, 1);
            curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
        }
        $content = curl_exec($ch);
        $response = curl_getinfo($ch);
        return $content;
    }

指定 第三个参数 的值为 GET 就可以了.

你是要采集get还是post请求的内容?

若是采集首页直接
echo file_get_contents('http://kakaku.com/pc/'); 即可
