$eq = new EncodeQ3boy($str);初始化类
//以下为ubbEncode参数
$eq->url = true; //启用url自动解析 默认false
$eq->html = true; //启用HTML编码（处理<，>，全角/半角空格，制表符，换行符）默认true
$eq->image = true; //启用图象标签解析 默认true
$eq->font = true; //启用字体标签解析 默认true
$eq->element = true; //启用外部元素解析 默认true
$eq->flash = true; //启用Flash解析 默认true
$eq->php = true; //启用语法高亮显示 默认true
//ubbEncode参数结束
echo($eq->getImageOpener());//输出图片自动缩放所需js函数
echo $eq->htmlEncode(); //输出ubb编码后字符串
echo"<hr>";
echo $eq->ubbEncode(); //输出ubb编码后字符串
echo"<hr>";
echo $eq->removeHtml(); //输出移除html标签的字符串
echo"<hr>";
echo $eq->ubbEncode(); //输出移除ubb标签的字符串
支持ubb标签列表：
图片类：
\[img\]http://www.aaa.com/aaa.gif\[/img\] 插入图片
\[limg\]http://www.aaa.com/aaa.gif\[/limg\] 图片左绕排
\[rimg\]http://www.aaa.com/aaa.gif\[/rimg\] 图片右绕排
\[cimg\]http://www.aaa.com/aaa.gif\[/cimg\] 图片居中绕排
文本控制类：
\[br\] 换行符
\[b\]粗体字\[b\]
\[i\]斜体字\[i\]
\[u\]下划线\[u\]
\[s\]删除线\[s\]
\[sub\]文字下标\[sub\]
\[sup\]文字上标\[sup\]
\[left\]文字左对齐\[left\]
\[right\]文字右对齐\[right\]
\[center\]文字居中\[center\]
\[align=(left|center|right)\]文字对齐方式\[align\]
\[size=(\[1-6\])\]文字大小\[size\]
\[font=(字体)\[font\]
\[color=(文字颜色)\]\[color\]
\[list\]无序列表\[list\]
\[list=s\]有序列表\[list\]
\[list=(A|1|I)\]有序列表（列表方式为（abc,123,I II III））\[list\]
\[list=(num)\]有序列表（自num开始计数）\[list\]
\[li\]列表单元项\[li\]
外部元素类：
\[url\]链接\[/url\]
\[url=(链接)\]链接文字\[/url\]
\[email\]邮件地址\[/email\]
\[email=(邮件地址)\]说明文字\[/email\]邮件地址
\[quote\]引用块\[/quote\]
\[iframe\]内插帧地址\[/iframe\]
\[iframe=(内插帧高度)\]内插帧地址\[/iframe\]
\[swf\]flash动画地址\[/swf\]
\[swf=宽度,高度\]flash动画地址\[/swf\]
代码块:
\[code\]\[/code\]
\[php\]\[/php\]
\[code 代码块名称\]\[/code\]
\[php 代码块名称\]\[/php\]
如需使用php语法高亮请务必在代码块两端加上"<©©>"标签
