php curl请求信息和返回信息设置代码实例

$ch=curl_init();
curl_setopt($ch,CURLOPT_URL,$url);
//curl_setopt($ch,CURLOPT_POST,1);
//curl_setopt($ch,CURLOPT_POSTFIELDS,$params);
curl_setopt($ch,CURLOPT_HEADER,1);//返回response头部信息
curl_setopt($ch,CURLOPT_NOBODY,1);//不返回response body内容
//curl_setopt($ch,CURLOPT_MAXREDIRS,1);//设置请求最多重定向的次数
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);//不直接输出response
curl_setopt($ch,CURLOPT_FOLLOWLOCATION,1);//如果返回的response 头部中存在Location值，就会递归请求
$content=curl_exec($ch);
$rinfo=curl_getinfo($ch);

echo $content,"

echo "
