A PHP-implemented UBB class! & Nbsp; & lt ;? Php <br/> & nbsp;/* <br/> & nbsp; If you have reprinted it, please indicate the author /*

Author: He Zhiqiang
File: ubb. php
Note: it is an improvement. In fact, the core function parse () has been completely rewritten, and the idea is different.
However, it is still inspired by the examples of He Zhiqiang, and there are several functions such as URLCHECK in the test examples that He Zhiqiang still uses. thank you, He Zhiqiang.
There is no color function yet, but I will add it.
If there are any bugs or inconveniences in the program, please MAIL me.
Thank you!
Improved functions:
Encode the string by UBB. Currently, this class only supports the following simple and practical encoding:
1. URL scheme
Http://www.phpexe.com/
Http: // header not required
Such as phpexe.com.
2. Email Reply
Demo@163.net
3. image seek
Same as the URL link, the previous http can also be avoided.
4. text
Bold Chinese
Italics
Underline
Note the following:
1. tags such as url, email, and img are case-insensitive.
2. a TAB key is not allowed in a tag, but spaces are allowed.
3. this class calls the htmlencode, htmlencode4textarea, emailcheck function, and urlcheck class.
4. nesting is supported after modification, but the url, email, and img tags are not allowed to be nested.
