PHP使用外部命令导出数据库,代码很简单,就不多废话了

<&#63;php

  // $dumpFileName目录要有可写权限
  $DbHost = 'localhost';
  $DbUser = 'root';
  $DbPwd  = '123456';
  $DbName = 'a';
  $fileName = $DbName . '_MySQL_data_backup_' . date('YmdHis) . '.sql';
  $dumpFileName= "/var/$fileName";

  header("Content-Disposition: attachment; filename=" . $fileName);
  header("Content-type: application/octet-stream");
  header("Pragma:no-cache"); 
  header("Expires:0");
  
  echo `mysqldump -h $DbHost -u$DbUser -p$DbPwd $DbName > $dumpFileName`;
  
  $hd = fopen($dumpFileName, 'rb');
  echo fread($hd, filesize($dumpFileName));
  fclose($hd);
