我試圖讓簡單的PHP腳本來備份databes使用mysqldump,但我得到這個錯誤:PHP:mysqldump的:找不到表「>」

mysqldump: Couldn't find table: ">" 

這是,我有寫功能使工作:

protected function dump($params, $dbs, $backup_folder) 
    { 
     if (!is_writable($backup_folder)) { 
      throw new Exception(sprintf('The backup folder is not writable: %s', 
             $backup_folder)); 
     } 

     $backup_folder = trim($backup_folder, "/"); // be sure that there is no/at the end 

     $baseCmd = 'mysqldump --hex-blob --routines --skip-lock-tables -h%s -u%s -p%s %s > %s'; 
     foreach ($dbs as $db) { 
      $dest = sprintf('%s/%s', $backup_folder, 
          $db . '_' . date('YmdHis') . '.sql'); 
      $cmd = sprintf($baseCmd, $params['host'], $params['user'], 
          $params['password'], $db, $dest); 
      echo "Exec: $cmd: "; 

      $last = system(escapeshellcmd($cmd), $res); 

      echo $res; 

      if (0 !== $res) { 
       echo "Fail"; 
      } else { 
       echo "Done \n"; 
      } 
     } 
    } 

通過此功能給予打印的命令:

mysqldump --hex-blob --routines --skip-lock-tables -hdb-backup -uroot -pMyPwd my_db_name > backups/my_db_name_20151010232734.sql 

當我執行從她這個命令它工作得很好,但不是來自PHP腳本。

我的配置是:

  • 我的桌面系統外殼:Ubuntu的15.04
  • MySQL服務器:安裝在Ubuntu服務器的Mysql 5.6 15.04
  • PHP版本:5.6.4

有什麼幫助嗎?

謝謝

escapeshellcmd()命令預先設置成\>

PHP documentation

Following characters are preceded by a backslash: #&;`|*?~<>^()[]{}$\, \x0A and \xFF.

你應該單獨逃脫每個參數與escapeshellarg(),或確保您的方法的參數($params$db$backup_folder)是有效的,並且不包含這些字符之一隻用

system($cmd, $res) 

我希望這有助於!
