php把文件上傳到遠程服務器上例子

在這里我們利用curl實現把本地服務器的文件通過curl發送請求給遠程服務器的php文件接受就實現了上傳，還一個是利用ftp來上傳方法也是php中的curl操作ftp服務器進行上傳。

我這里寫的是用curl的代碼

本地代碼如下：

<?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);
?>

遠程服務器接受端代碼：

<?php
    if($_FILES)
    {
        $filename = $_FILES['img']['name'];
        $tmpname = $_FILES['img']['tmp_name'];
        if(move_uploaded_file($tmpname, dirname(__FILE__).'/img/'.$filename))
        {
            echo json_encode('上傳成功');
        }
        else
        {
            $data = json_encode($_FILES);
            echo $data;
        }
    }
?>

例子，同樣是利用curl不過這是利用ftp

<?php
$localfile = "php_homepage.txt";
$fp = fopen ($localfile, "r");
$arr_ip = gethostbyname(www.111cn.net);
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);
?>
