本文实例讲述了PHP CURL实现模拟登陆并上传文件操作。分享给大家供大家参考，具体如下：

<?PHP
header('content-type:text/html;charset=gb2312');
//要注意你需要上传的网站服务器的运行环境，还要看它的请求是否被压缩和转码还有就是
//在框架中或者说PHP5.3以下的版本可以用@，但是其它的就只能用new CURLfile（）函数来转化文件了
//注意你要发送的服务器的header头的结构和特殊参数，实在不行就自己构建一个。废话不多说，直接上代码。
function curl_form($post_data,$sumbit_url,$http_url,$cookie_file){
  $headers = array();
  $headers[] = 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8';
  $headers[] = 'Cache-Control: max-age=0';
  $headers[] = 'Accept-Encoding: gzip,deflate';
  $headers[] = 'Origin: http://my.***.com';
  $headers[] = 'Accept-Language: zh-CN,zh;q=0.8,en-US;q=0.5,en;q=0.3';
  $headers[] = 'Upgrade-Insecure-Requests: 1';
  $headers[] = 'Content-Type: application/x-www-form-urlencoded';
  $headers[] = 'User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:28.0) Gecko/20100101 Firefox/28.0';
  $headers[] = 'Connection: keep-alive';
//  $headers[] = 'Cookie: ASPSESSIONIDCCTCTQQC=KBGLPDKBIKDIDCBGFOKNMKOE';
  //初始化
  $ch = curl_init();
  //设置变量
  curl_setopt($ch,CURLOPT_URL,$sumbit_url);
  curl_setopt($ch,CURLOPT_HTTPHEADER,$headers);
  curl_setopt($ch,CURLOPT_COOKIEFILE,$cookie_file);
  curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);//执行结果是否被返回，0是返回，1是不返回
  curl_setopt($ch,CURLOPT_HEADER,0);//参数设置，是否显示头部信息，1为显示，0为不显示
  curl_setopt($ch,CURLOPT_REFERER,$http_url);
  //表单数据，是正规的表单设置值为非0
  curl_setopt($ch,CURLOPT_POST,1);
  curl_setopt($ch,CURLOPT_TIMEOUT,30);
  curl_setopt($ch,CURLOPT_PROXY,'127.0.0.1:8888');
//  curl_setopt($ch,CURLOPT_ENCODING,"");
//  curl_setopt($ch,'gzip,deflate');
  curl_setopt($ch,CURLOPT_POSTFIELDS,http_build_query($post_data));
  //执行并获取结果
  $output = curl_exec($ch);
  if($output === FALSE)
  {
    echo "<br/>","cUrl Error:".curl_error($ch);
  }else{
    return $output;
  }
  //  释放cURL句柄
  curl_close($ch);
}
$temp = array();
$temp['title'] = iconv( "utf-8","gb2312//IGNORE","牛排店加盟");
$temp['ly'] = iconv( "utf-8","特色餐饮加盟");
