1. 修改数据库名。这是常用方法,将数据库名该成怪异名字或长名字,以防别人猜测。一旦被人猜到,别人还是能下载数据库文件,但几率不大。如将数据库database.mdb改成dslfjds$^ijjkgf.mdb等 2. 修改数据库后缀。一般改成database.asp 、database.asa、 datab
1. 修改数据库名。这是常用方法,将数据库名该成怪异名字或长名字,以防别人猜测。一旦被人猜到,别人还是能下载数据库文件,但几率不大。如将数据库database.mdb改成dslfjds$^&ijjkgf.mdb等
2. 修改数据库后缀。一般改成database.asp 、database.asa、 database.inc、 database.cgi、 database.dll等等,注意要在IIS中设置这些后缀的文件不能被解析。
3. 将数据库database.mdb改成#database.mdb 。 这是最简单有效的办法。
分析:假设别人得到你的数据库地址串将是:http://www.yourserver.com/yourfolder/#database.mdb
但实际上他得到是:http://www.yourserver.com/yourfolder/
因为#在这里起到间断符的作用,地址串遇到#号,自动认为访问地址串结束。注意:不要设置目录可访问。用这种方法,不管别人用何种工具都无法下载,如flashget,网络蚂蚁等。
注:只要数据库文件名任何地方含有'#',别人都无法正常下载。同理,空格号也可以起到'#'号作用,但必须是文件名中间出现空格。
4. 将数据库连接文件放到其他虚拟目录下。
5. 将 Access数据库加密。
以上只列出常用之法,为增加保险性,可以几种方法同时使用。

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),
