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("rn","
",$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);
$Text=preg_replace("/[fly](.+?)[/fly]/is","",$Text);
$Text=preg_replace("/[move](.+?)[/move]/is","",$Text);
$Text=preg_replace("/[shadow=([#0-9a-z]{1,10}),([0-9]{1,3}),([0-9]{1,2})](.+?)[/shadow]/is","
| \4 |
return $Text;
}
}
希望本文所述对大家的php程序设计有所帮助。
