使用MySql ODBC进行MYsql和MSsql的数据转换_MySQL
ODBC
将Mysql数据库转换为MSsql的数据库,或者将Mssql数据库转换为Mysql的数据库,在NT环境下很多时候都会用到。使用MySql ODBC后就比较好办,可以使用MSSQL7的管理工具,也可以使用mysql的管理工具,更可以使用其它方的管理工具
这里介绍一个使用SQL7的MMC的方法 ,将MSsql7的数据转化为Mysql的数据库,将源和目的反之,就可以将Mysql的数据库转化为Mssql7的数据库。
1.安装Mysql的ODBC接口,可以在本站下载
2.建立Mysql的DSN,可以建系统DSN,这里命名testmysql,填写IP,dababase,用户名口令等项,完成
3.在SQL7的MMC中,选择要导出的数据库,右键选择All Tasks->Export Datas...
4.开始DTS Export Wizerd...,
Choose a Data Source:Microsoft OLE DB Privoder for SQL Server
server:你的MSsql7数据库的服务器
是否使用NT认证和用户名口令看你自己的了
最后选择一个Database,如:mynews(你自己要导到mysql中的数据库)
下一步
5.Choose a Destination:选Mysql
User/System DSN,如果建立过就选择,如果没有建立就新建。
6.Specify Table Copy or Query
Copy table(s) from the source database,从源数据库拷贝表开始
7.Select Source Table
选择要拷贝的表,如果不想仔细调整,就选择全部吧。
8.Run immediately,当然要立即执行,下一步再选完成,就开始转换。
这个转换有时一部分表可能要失败,双击失败的表格,看看什么原因,一般是SQL7的数据类型问题,作一些小的修改就应该可以了。

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
