如何在php中使用mysqldump命令？

Question

我想备份我的数据库。所以我使用了这个命令

$command = "mysqldump --user=root asset_management > D:\assetmanagement\public\backup\backup.sql"; system($command);

但这将生成一个空的sql文件。有人能帮上忙吗？

Answer 1

假设mysqldump位于C:/wamp/bin/mysql/mysql5.1.33/bin/文件夹中

$mysqlPath="C:/wamp/bin/mysql/mysql5.1.33/bin/";
//There should be password for root user. Blank password will not work.

$command = $mysqlPath . "mysqldump.exe asset_management > D:\assetmanagement\public\backup\backup.sql --user=root --password=yourpassword ";

Answer 2

$command = "mysqldump --user=root -pass=yourpassword asset_management > D:\assetmanagement\public\backup\backup.sql"; system($command);
