php本地文件上传到远程服务器

利用curl实现把本地服务器的文件通过curl发送请求给远程服务器的php文件接受就实现了上传，还一个是利用ftp来上传方法也是php中的curl操作ftp服务器进行上传。

本地代码如下：

    header("content-type:text/html;charset=utf8");
    $curl = curl_init();
    $data = array("img"=>"@". dirname(__FILE__)."/img/login.gif");
    curl_setopt($curl, CURLOPT_URL, "http://www.lituanmin.com/uploadimg.php");
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_POST, true);
    curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
    $result = curl_exec($curl);
    curl_close($curl);
    echo json_decode($result);

远程服务器接受端代码：

    if($_FILES)
    {
        $filename = $_FILES["img"]["name"];
        $tmpname = $_FILES["img"]["tmp_name"];
        if(move_uploaded_file($tmpname, dirname(__FILE__)."/img/".$filename))
        {
            echo json_encode("上传成功");
        }
        else
        {
            $data = json_encode($_FILES);
            echo $data;
        }
    }

    利用curl不过这是利用ftp

    $localfile = "php_homepage.txt";
    $fp = fopen ($localfile, "r");
    $arr_ip = gethostbyname(www.lituanmin.com);
    echo $arr_ip;
    $ftp = "ftp://".$arr_ip."/public_html/".$localfile;  
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_VERBOSE, 1);
    curl_setopt($ch, CURLOPT_USERPWD, "***:****");
    curl_setopt($ch, CURLOPT_URL, $ftp);
    curl_setopt($ch, CURLOPT_PUT, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_INFILE, $fp);
    curl_setopt($ch, CURLOPT_INFILESIZE, filesize($localfile));
    $http_result = curl_exec($ch);
    $error = curl_error($ch);
    echo $error."";
    $http_code = curl_getinfo($ch ,CURLINFO_HTTP_CODE);curl_close($ch);
    fclose($fp);
