php+curl上传文件到远程服务器

　　1.将PHP安装文件夹下的三个文件php_curl.dll(可能在ext文件夹中),libeay32.dll,ssleay32.dll 复制到 %windir%/system32下;
　　2.打开php.ini(可能在PHP环境的安装目录下，默认在c:\WINDOWS目录下)，将;extension=php_curl.dll头部的分号去掉;

　　3.重启php的服务(apache或者IIS)，如重启IIS，运行iisreset即可。

二、注意事项。

注意服务器文件夹的权限，

php.ini 里 upload_tmp_dir 设置一个全新的目录 也赋予Everyone 读写权限。

上传文件的目标目录也赋予Everyone 读写权限。

三、直接上代码

1、文件curlTest.php:

 0, 'message' => 'ok');        ini_set('upload_max_filesize', '20M');        ini_set('post_max_size', '20M');        ini_set('memory_limit', '128M');        //接收上传的远程地址        $url = isset($_POST['url']) ? trim($_POST['url']) : '';               $url ="www.123.com/k1/upload.php";        if (empty($url)) {            $result['code'] = 40001;            $result['message'] = 'url不能为空';            //Helper_Http::writeJson(200,$result);        }        $file = $_FILES['file'];        print_r($_FILES);        if ($file['error'] != 0) {            $result['code'] = 40001;            $result['message'] = '上传出错';            //Helper_Http::writeJson(200,$result);            echo 1;        } else {            $filename = $file['name'];            $tmpfile = $file['tmp_name'];            $filetype = $file['type'];            $data = upload_file($url, $filename, $tmpfile, $filetype);            echo $data;            print_r ($url);            die;        }    }         /**     * curl上传文件     *      * @param unknown $url     * @param unknown $filename     * @param unknown $path     * @param unknown $type     */    function upload_file($url,$filename,$path,$type){    	echo 3;    	echo $path;        //php 5.5以上的用法        if (class_exists('\CURLFile')) {            $data = array('file' => new \CURLFile(realpath($path),$type,$filename));        } else {            $data = array(                'file'=>'@'.realpath($path).";type=".$type.";filename=".$filename            );        }        echo 'data:';        print_R($data);        $ch = curl_init();        curl_setopt($ch, CURLOPT_URL, $url);        curl_setopt($ch, CURLOPT_POST, true );        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);        curl_setopt($ch, CURLOPT_HEADER, false);        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);        $return_data = curl_exec($ch);        curl_close($ch);        echo $return_data;    }?>

2、文件upload.php：

 "; print_r($_FILES);  $uploaddir = 'D:/temp/caches/'; $uploadfile = $uploaddir . basename($_FILES['file']['name']);  echo '
'; if (move_uploaded_file($_FILES['file']['tmp_name'], $uploadfile)) { 	echo "File is valid, and was successfully uploaded.\n"; } else { 	echo "Possible file upload attack!\n"; }  echo 'Here is some more debugging info:'; ?>
