php程序怎么上传服务器,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);
