$eq = new EncodeQ3boy($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.php.cn/[/img] 插入图片
[limg]http://www.php.cn/[/limg] 图片左绕排
[rimg]http://www.php.cn/[/rimg] 图片右绕排
