php實現ftp上傳的類與調用樣本

仿照網上的例子寫的一個ftp上傳類，很簡單，適合新手朋友參考。 1、檔案上傳類 ftp.class.php 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 啟用被動模式; $status = 1; } else { $status = 3; } } else { $status = 2; } } //R 切換目錄; function cd($dir) { return ftp_chdir($this->ftpR, $dir); } //R 返回當前路勁; function pwd() { return ftp_pwd($this->ftpR); } //R 建立目錄 function mkdir($directory) { return ftp_mkdir($this->ftpR,$directory); } //R 刪除目錄 function rmdir($directory) { return ftp_rmdir($this->ftpR,$directory); } //R 上傳檔案; 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 下載檔案; 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 $flag; } //R 檔案大小; function size($file) { return ftp_size($this->ftpR, $file); } //R 檔案是否存在; function isFile($file) { if ($this->size($file) >= 0) { return true; } else { return false; } } //R 檔案時間 function fileTime($file) { return ftp_mdtm($this->ftpR, $file); } //R 刪除檔案; function unlink($file) { return ftp_delete($this->ftpR, $file); } function nlist($dir = '/service/resource/') { return ftp_nlist($this->ftpR, $dir); } //R 關閉串連; function bye() { return ftp_close($this->ftpR); }}?> 2、調用樣本 uplaod.php put($localfile, $remotefile); //FTP上傳原圖到遠程伺服器 $ftp->bye(); //關閉FTP串連 unlink($workDir."/".$img_name) or die("Cannot delete uploaded file from working directory -- manual deletion recommended"); if(!$ftpput){ return false; } else{ return $img_path.'/'.$img_name; }?>
