这篇文章主要介绍了php实现过滤UBB代码的类,涉及php正则表达式的操作技巧,具有一定参考借鉴价值,需要的朋友可以参考下

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","
",$Text);
$Text=ereg_replace("\[br\]","
",$Text);
$Text=nl2br($Text);
$Text=stripslashes($Text);
$Text=preg_replace("/\\t/is"," ",$Text);
$Text=preg_replace("/\[url\](http:\/\/.+?)\[\/url\]/is","\\1",$Text);
$Text=preg_replace("/\[url\](.+?)\[\/url\]/is","\\1",$Text);
$Text=preg_replace("/\[url=(http:\/\/.+?)\](.+?)\[\/url\]/is","\\2",$Text);
$Text=preg_replace("/\[url=(.+?)\](.+?)\[\/url\]/is","\\2",$Text);
$Text=preg_replace("/\[color=(.+?)\](.+?)\[\/color\]/is","\\2",$Text);
$Text=preg_replace("/\[font=(.+?)\](.+?)\[\/font\]/is","\\2",$Text);
$Text=preg_replace("/\[email=(.+?)\](.+?)\[\/email\]/is","\\2",$Text);
$Text=preg_replace("/\[email\](.+?)\[\/email\]/is","\\1",$Text);
$Text=preg_replace("/\[i\](.+?)\[\/i\]/is","\\1",$Text);
$Text=preg_replace("/\[u\](.+?)\[\/u\]/is","\\1",$Text);
$Text=preg_replace("/\[b\](.+?)\[\/b\]/is","\\1",$Text);
$Text=preg_replace("/\[fly\](.+?)\[\/fly\]/is","\\1",$Text);
$Text=preg_replace("/\[move\](.+?)\[\/move\]/is","\\1",$Text);
$Text=preg_replace("/\[shadow=([#0-9a-z]{1,10})\,([0-9]{1,3})\,([0-9]{1,2})\](.+?)\[\/shadow\]/is","

\\4

",$Text);
return $Text;
