百度站长平台php的主动提交源码是：
$urls = array(
'http://www.quyuexuan.com/article/31',
);
$api = 'http://data.zz.baidu.com/urls?site=www.quyuexuan.com&token=Ka5ezP4FdBTLx8fr';
$ch = curl_init();
$options = array(
CURLOPT_URL => $api,
CURLOPT_POST => true,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_POSTFIELDS => implode("\n", $urls),
CURLOPT_HTTPHEADER => array('Content-Type: text/plain'),
);
curl_setopt_array($ch, $options);
$result = curl_exec($ch);
echo $result;如果根目录放个baidu.php文件，该怎么写代码调用最新的内容配合提交代码，我只需浏览器浏览这个文件就实现主动提交呢？
