We all know the importance of databases for the network. due to the complexity of cgi, asp and php + mysql have become the mainstream. almost all personal webpages use message books, but the requested message books are unstable. this has caused a lot of inconvenience for online communication. therefore, more and more friends wish to have their own message books.
However, few free personal homepages support asp and php. I recommend you now Osso Network (http://www.oso.com.cn) Support php. this gives you the foundation to have your own message book. now, I will use an example in a text message book to describe the simple use of php.
First, let's determine the process of leaving a message: Write, send, and view the message. (Search) and so on. for Bamboo, it is indispensable to manage message books. in this way, we may wish to locate 6 PHP files and 1 text file. the six PHP files are: guest. php manage. php reply. php sys. php del. php edit. php, 1 text file: guest.txt
Let's take a look at the content of guest. php. Of course, you can directly put the following content on your php webpage. Please respect the work of the author. Thank you.
----------------------
// Guest. php: <?
