php备份mysql:

第一种方法:
"C:\Program Files\MySQL\MySQL Server 5.5\bin\mysqldump -uroot -hlocalhost -proot aa>C:\\www\\aa\\admin\\bak\\".$_POST[b_name];
exec($mysqlstr);备份出来是0字节
第二种方法:
"C:\Program Files\MySQL\MySQL Server 5.5\bin\mysqldump -uroot -hlocalhost -proot aa>..bak";备份出来依然是0字节,
语句到底该怎样写,请求各位了。

在命令行里执行
C:\Program Files\MySQL\MySQL Server 5.5\bin>mysqldump -uroot -proot -hl
ocalhost aa >C:\www\aa\admin\bak\20130327.sql
结果是没问题的,只是瑞星提示拦截,其他正常。

先mark一个我去研究一下

C:\Program Files\MySQL\MySQL Server 5.5\bin\mysqldump -u root -proot aa  > C:\www\aa\admin\bak\20130327.sql
Copy after login


-u root中间加个空格。

测试成功代码如下:

exec('e:\xampp\mysql\bin\mysqldump -unowphp -pnowphp examples>e:\\back1253.sql')
Copy after login

感谢大家,问题解决,原因是mysql所在目录不能有空格,试验完毕,mark也加分

mysqldump所在目录
