本文实例讲述了php实现过滤ubb代码的类。分享给大家供大家参考。具体如下:

php代码如下:

复制代码 代码如下:
class day{
   function ubb($text) {      /// ubb代码转换
        //$text=htmlspecialchars($text);
        //$text=ereg_replace("\r\n","<br>",$text);
        $text=ereg_replace("\[br\]","<br />",$text);
        $text=nl2br($text);
        $text=stripslashes($text);
        $text=preg_replace("/\\t/is"," ",$text);
        $text=preg_replace("/\[url\](http:\/\/.+?)\[\/url\]/is","<a href=\"\\1\" target=\"new\"><u>\\1</u></a>",$text);
        $text=preg_replace("/\[url\](.+?)\[\/url\]/is","<a href=\"http://\\1\" target=\"new\"><u>\\1</u></a>",$text);
        $text=preg_replace("/\[url=(http:\/\/.+?)\](.+?)\[\/url\]/is","<a href=\"\\1\" target=\"new\"><u>\\2</u></a>",$text);
        $text=preg_replace("/\[url=(.+?)\](.+?)\[\/url\]/is","<a href=\"http://\\1\" target=\"new\"><u>\\2</u></a>",$text);
        $text=preg_replace("/\[color=(.+?)\](.+?)\[\/color\]/is","<font color=\"\\1\">\\2</font>",$text);
        $text=preg_replace("/\[font=(.+?)\](.+?)\[\/font\]/is","<font face=\"\\1\">\\2</font>",$text);
        $text=preg_replace("/\[email=(.+?)\](.+?)\[\/email\]/is","<a href=\"mailto:\\1\"><u>\\2</u></a>",$text);
        $text=preg_replace("/\[email\](.+?)\[\/email\]/is","<a href=\"mailto:\\1\"><u>\\1</u></a>",$text);
        $text=preg_replace("/\[i\](.+?)\[\/i\]/is","<i>\\1</i>",$text);
        $text=preg_replace("/\[u\](.+?)\[\/u\]/is","<u>\\1</u>",$text);
        $text=preg_replace("/\[b\](.+?)\[\/b\]/is","<b>\\1</b>",$text);
        $text=preg_replace("/\[fly\](.+?)\[\/fly\]/is","<marquee width=\"98%\" behavior=\"alternate\" scrollamount=\"3\">\\1</marquee>",$text);
        $text=preg_replace("/\[move\](.+?)\[\/move\]/is","<marquee width=\"98%\" scrollamount=\"3\">\\1</marquee>",$text);
        $text=preg_replace("/\[shadow=([#0-9a-z]{1,10})\,([0-9]{1,3})\,([0-9]{1,2})\](.+?)\[\/shadow\]/is","<table width=\"*\"><tr><td style=\"filter:shadow(color=\\1, direction=\\2 ,strength=\\3)\">\\4</td></tr></table>",$text);
        return $text;
  }
}

希望本文所述对大家的php程序设计有所帮助。
