UBB转换HTML请教

$Text=preg_replace("/\[img=(.+?),(.+?)\](.+?)\[\/img\]/is","<img src=\\3 width=\\1 height=\\2>",$Text)

$Text=ereg_replace(" ","nbsp",$Text)

你用什么语言来写，必须要正则表达式才好做，你如果要求用DELPHI、C++这些东西来做，要做死人的哦。

如果用ASP、PERL、PHP，基本上可以用它原来的语法，你改写成一个函数就行了。

ubb

定义：UBB代码是HTML（标准通用标记语言下的一个应用）的一个变种，是Ultimate Bulletin Board （国外的一个BBS程序）采用的一种特殊的TAG。

介绍：UBB 标记是您可能已经熟悉的 HTML标记的一种变种。基本上，它允许您在文章中添加本来需要 HTML 标记的功能或风格。即使您所在的讨论区不允许使用 HTML 标记，UBB 标记仍然可以使用。因为比 HTML 要求更少的编码技术，您也许更愿意使用 UBB 标记，即便讨论区允许使用 HTML 标记。

UBB与HTML：UBB与HTML一样，都是用来标记文本，并赋予文本一定的样式动作，但UBB作为HTML的一个变种，具备有代码简单、功能实用、上手简单、安全性高、不存在xss注入问题，因此被广泛引用于论坛讨论组等网站。

但因为毕竟HTML是主流的标记语言，而且HTML语法较UBB丰富，因此存在着将UBB和HTML转化的需求，对于UBB和HTML之间的转换，仅仅需要对应UBB的语法标签，利用正则表达式匹配即可完成 。
