原作者: 何志強
改良: SonyMusic[ sonymusic@163.net ]
檔: ubb.php
備註: 說是改進,其實核心函數parse()已經完全重寫了,而且思路也是不一樣的。
不過仍是受何志強的例子的啟發,而且測試的例子還有URLCHECK等幾個函數也是沿用的何志強的程序,謝謝何志強。
目前還沒有顏色的功能,但我會加入的。
如果在程序上有什麼BUG或不便的地方,請給我MAIL。
謝謝!
改進功能:
對字串進行UBB編碼,該類別目前只支援下列幾個簡單且實用的編碼:
1. URL褳接
[url] http://phpuser. com/ [/url]
http://頭可以不需要
如[url]phpuser.com[/url]也是可以的。
2. Email褳接
[email] sonymusic@163.net [/email]
3. 圖片褳接
[img] http://www.phpchina.com/images/logo .gif [/img]
同URL連結一樣,前面的http也可以不要。
4. 文字方面
[b]粗體字[/b]
[i]斜體字[/i]
[u]加底線[/u]
[h1] 1號標題字[/h1] ... [h6]6號標題字[/h6]
[sup][/sup]
[sub][/sub]
[tt][/ tt]
[s][/s]
[strike][/strike]
[em][/em]
[strong][/strong]
[code][/ code]
[samp][/samp]
[kbd][/kbd]
[var][/var]
[dfn][/dfn]
[cite][/ cite]
[small][/small]
[big][/big]
[blink][/blink]
注意以下幾點:
1. url,email,img等標籤是不分大小寫的.
2. 在標籤中不允許有TAB鍵出現,但空格允許。
3. 類別要呼叫htmlencode,htmlencode4textarea,emailcheck函數和urlcheck類別.
4. 修改後支援巢狀,但url,email,img這三個標籤不是允許巢狀的。
