The example in this article describes how PHP uses curl to simulate post uploading and receiving files. Share it with everyone for your reference, the details are as follows:

public function Action_Upload(){
     $this->path_config();
    exit();
    $furl="@d:\develop\JMFrameworkWithDemo.rar";
    $url= "http://localhost/DemoIndex/curl_pos/";
    $this->upload_file_to_cdn($furl, $url);
}
public function upload_file_to_cdn($furl,$url){
    //  初始化
    $ch = curl_init();
    // 要上传的本地文件地址"@F:/xampp/php/php.ini"上传时候,上传路径前面要有@符号
    $post_data = array (
      "upload" => $furl
    );
    //print_r($post_data);
    //CURLOPT_URL 是指提交到哪里?相当于表单里的“action”指定的路径
    //$url = "http://localhost/DemoIndex/curl_pos/";
    //  设置变量
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);//执行结果是否被返回,0是返回,1是不返回
    curl_setopt($ch, CURLOPT_HEADER, 0);//参数设置,是否显示头部信息,1为显示,0为不显示
    //伪造网页来源地址,伪造来自百度的表单提交
    curl_setopt($ch, CURLOPT_REFERER, "http://www.baidu.com");
    //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, 100);//设置curl执行超时时间最大是多少
    //使用数组提供post数据时,CURL组件大概是为了兼容@filename这种上传文件的写法,
    //默认把content_type设为了multipart/form-data。虽然对于大多数web服务器并
    //没有影响,但是还是有少部分服务器不兼容。本文得出的结论是,在没有需要上传文件的
    //情况下,尽量对post提交的数据进行http_build_query,然后发送出去,能实现更好的兼容性,更小的请求数据包。
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
    //   执行并获取结果
    curl_exec($ch);
    if(curl_exec($ch) === FALSE)
    {
      echo "<br/>"," cUrl Error:".curl_error($ch);
    }
    //  释放cURL句柄
    curl_close($ch);
    echo "aaa45";
}
function action_curl_pos(){
    var_dump($_FILES);
    $aa= move_uploaded_file($_FILES["upload"]["tmp_name"], "/wamp/tools/1.rar");
    if($aa){
      echo "11";
    }
}
