PHP通过FTP上传文件

上传时先传至本地对文件作必要的修改,如加水印等等操作,然后再通过FTP传至远程服务器.

使用示例:
//上传图片

if ($_FILES['pic']['name'])
{
$file_path='/opt/www/img/';
$pic = upload('pic', $filename, 'jpg|jpeg|gif|bmp|png', $file_path);
if(!$pic)
{
echo "图片上传失败!";
exit;
}
require_once(ROOT_PATH . 'Lib/Class/Ftp.class.php');
$ftp = new ftp("127.0.0.1","gamezeroftp","123456","/opt/www");
$localfile='/opt/www/img/'.$pic;
$remotefile='/opt/www/gamepics/'.$pic;
$ftpput = $ftp->put($localfile, $remotefile); //FTP上传原图到远程服务器
if(!$ftpput){
echo "上传图片到远程服务器失败!";
}
$ftp->bye(); //关闭FTP连接
}
附上FTP操作类:


ftpUrl=$ftpUrl;
}
if($ftpUser){
$this->ftpUser=$ftpUser;
}
if($ftpPass){
$this->ftpPass=$ftpPass;
}
if($ftpUrl){
$this->ftpDir=$ftpDir;
}
if ($this->ftpR = ftp_connect($this->ftpUrl, 21)) {
if (ftp_login($this->ftpR, $this->ftpUser, $this->ftpPass)) {
if (!empty($this->ftpDir)) {
ftp_chdir($this->ftpR, $this->ftpDir);
}
ftp_pasv($this->ftpR, true);//R 启用被动模式;
$status = 1;
} else {
$status = 3;
}
} else {
$status = 2;
}
}
//R 切换目录;
function cd($dir) {
return ftp_chdir($this->ftpR, $dir);
}
//R 返回当前路劲;
function pwd() {
return ftp_pwd($this->ftpR);
}
//R 创建目录
function mkdir($directory) {
return ftp_mkdir($this->ftpR,$directory);
}
//R 删除目录
function rmdir($directory) {
return ftp_rmdir($this->ftpR,$directory);
}
//R 上传文件;
function put($localFile, $remoteFile = '') {
if ($remoteFile == '') {
$remoteFile = end(explode('/', $localFile));
}
$res = ftp_nb_put($this->ftpR, $remoteFile, $localFile, FTP_BINARY);
while ($res == FTP_MOREDATA) {
$res = ftp_nb_continue($this->ftpR);
}
if ($res == FTP_FINISHED) {
return true;
} elseif ($res == FTP_FAILED) {
return false;
}
}
//R 下载文件;
function get($remoteFile, $localFile = '') {
if ($localFile == '') {
$localFile = end(explode('/', $remoteFile));
}
if (ftp_get($this->ftpR, $localFile, $remoteFile, FTP_BINARY)) {
$flag = true;
} else {
$flag = false;
}
return $flag;
}
//R 文件大小;
function size($file) {
return ftp_size($this->ftpR, $file);
}
//R 文件是否存在;
function isFile($file) {
if ($this->size($file) >= 0) {
return true;
} else {
return false;
}
}
//R 文件时间
function fileTime($file) {
return ftp_mdtm($this->ftpR, $file);
}
//R 删除文件;
function unlink($file) {
return ftp_delete($this->ftpR, $file);
}
function nlist($dir = '/service/resource/') {
return ftp_nlist($this->ftpR, $dir);
}
//R 关闭连接;
function bye() {
return ftp_close($this->ftpR);
}
}
