usage:
$eq = new EncodeQ3boy($str);初始化類
//以下為ubbEncode參數
$eq->url = true; //啟用url自動解析 默認false
$eq->html = true; //啟用HTML編碼（處理<，>，全角/半角空格，制表符，換行符）默認true
$eq->image = true; //啟用圖象標簽解析 默認true
$eq->font = true; //啟用字體標簽解析 默認true
$eq->element = true; //啟用外部元素解析 默認true
$eq->flash = true; //啟用Flash解析 默認true
$eq->php = true; //啟用語法高亮顯示 默認true
//ubbEncode參數結束
echo($eq->getImageOpener());//輸出圖片自動縮放所需js函數
echo $eq->htmlEncode(); //輸出ubb編碼後字符串
echo"<hr>";
echo $eq->ubbEncode(); //輸出ubb編碼後字符串
echo"<hr>";
echo $eq->removeHtml(); //輸出移除html標簽的字符串
echo"<hr>";
echo $eq->ubbEncode(); //輸出移除ubb標簽的字符串
支持ubb標簽列表：
圖片類：
[img]http://www.aaa.com/aaa.gif[/img] 插入圖片
[limg]http://www.aaa.com/aaa.gif[/limg] 圖片左繞排
[rimg]http://www.aaa.com/aaa.gif[/rimg] 圖片右繞排
[cimg]http://www.aaa.com/aaa.gif[/cimg] 圖片居中繞排

[font=(字體)[font]
[color=(文字顏色)][color]
[list]無序列表[list]
[list=s]有序列表[list]
[list=(A|1|I)]有序列表（列表方式為（abc,123,I II III））[list]
[list=(num)]有序列表（自num開始計數）[list]
[li]列表單元項[li]
外部元素類：
