//获取文件名
$selectFile = basename($fileName);
// 进入指定路径
if(@ftp_chdir($this->ftpObj,$ftpPath)) {
//$localBase 如果不存在,新创建目录,务必确保 有创建权限
if(!is_dir($this->localBase)){
mkdir($this->localBase, 0777);
}
$toFile = $this->localBase.$fileName;
if(ftp_get($this->ftpObj, $toFile, $selectFile, FTP_BINARY)) { //下载指定的FTP文件到指定的本地文件

return false;
}
}else {
return false;
}

function ftp_quit(){

}
调用就更简单了
$ftpObj = new FtpClass();
$ftpObj->ftp_connect();
$filename = '/config/config.sample.php';
$ftpObj->ftp_download_file($filename);
$ftpObj->ftp_quit();
exit();
