php7 curl upload file

php7 uses curl to upload files and returns error code 26; the code is as follows:

<code>    $size    =    filesize($path);//文件大小
    $ch = curl_init($url);
    $cfile = curl_file_create($path);
    if (is_null($post_data)) {
        $data = array('media' => $cfile);
    }else{
        $data = array('media' => $cfile,'description'=>$post_data);
    }
    curl_setopt($ch, CURLOPT_POST,1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    curl_setopt($ch, CURLOPT_INFILESIZE,$size);
    curl_setopt($ch, CURLOPT_HEADER, 0); // 显示返回的Header区域内容
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // 获取的信息以文件流的形式返回
    $info    =    curl_exec($ch);
    if (curl_errno($ch)) {
        var_dump(curl_errno($ch));
        return FALSE;
    }
    curl_close($ch); // 关闭CURL会话
    return $info; // 返回数据</code>

I used the CURLFile function after checking the manual, but the error returned was still error code 26, or there was a lack of multimedia problems, etc.

<code>    $cfile  =   new \CURLFile($path,$upload_type,$upload_name);   </code>
