php把文件上传到远程服务器上例子

在这里我们利用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.

我这里写的是用curl的代码,本地代码如下:

<?php

    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.demo.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,代码如下:

<?php

    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;

        }

    }

?>

例子,同样是利用curl不过这是利用ftp,代码如下:

<?php

$localfile = "php_homepage.txt";

$fp = fopen ($localfile, "r");

$arr_ip = gethostbyname(www.phpfensi.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."<br>";

$http_code = curl_getinfo($ch ,CURLINFO_HTTP_CODE);curl_close($ch);

fclose($fp);

?>
