PHP使用外部命令导出数据库，代码很简单，就不多废话了
<"/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);
?>
