详解php用curl调用接口方法，get和post两种方式

<"";
    foreach ( $post_data as $k => $v ) 
    { 
      $o.= "$k=" . urlencode( $v ). "&" ;
    }
    $post_data = substr($o,0,-1);
    $key=md5(base64_encode($post_data));
    if($ispost){
      $url=$url;
    }else{
      $url = $url.'"Content-type: text/html; charset=utf-8");
    $ch = curl_init();//初始化curl
    curl_setopt($ch, CURLOPT_URL,$url);//抓取指定网页
    curl_setopt($ch, CURLOPT_HEADER, 0);//设置header
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//要求结果为字符串且输出到屏幕上
    if($ispost){
      curl_setopt($ch, CURLOPT_POST, 1);//post提交方式
      curl_setopt($ch, CURLOPT_POSTFIELDS, $curlPost);
    }
    $data = curl_exec($ch);//运行curl
    curl_close($ch);
    return $data;
  }
