php 使用 CURL 获取数据

function http_curl($url, $type = ‘get‘, $data = ‘‘){
  $cl = curl_init();
  curl_setopt($cl, CURLOPT_URL, $url);
  curl_setopt($cl, CURLOPT_RETURNTRANSFER, 1);
  if($type == ‘post‘){
    curl_setopt($cl, CURLOPT_POST, 1);
    curl_setopt($cl, CURLOPT_POSTFIELDS, $data);
  }
  $output = curl_exec($cl);
  curl_close($cl);
  return $output;
}
