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);

//$Text=ereg_replace("rn","<br>",$Text);

$Text=ereg_replace("[br]","<br />",$Text);

$Text=nl2br($Text);

$Text=stripslashes($Text);

$Text=preg_replace("/t/is"," ",$Text);

$Text=preg_replace("/[url](http://.+"<a href="1" target="new"><u>1</u></a>",$Text);

$Text=preg_replace("/[url](.+"<a href="http://1" target="new"><u>1</u></a>",$Text);

$Text=preg_replace("/[url=(http://.+?)](.+"<a href="1" target="new"><u>2</u></a>",$Text);

$Text=preg_replace("/[url=(.+?)](.+"<a href="http://1" target="new"><u>2</u></a>",$Text);

$Text=preg_replace("/[color=(.+?)](.+","<font color="1">2</font>",$Text);

$Text=preg_replace("/[font=(.+?)](.+","<font face="1">2</font>",$Text);

$Text=preg_replace("/[email=(.+?)](.+","<a href="mailto:1"><u>2</u></a>",$Text);

$Text=preg_replace("/[email](.+","<a href="mailto:1"><u>1</u></a>",$Text);

$Text=preg_replace("/[i](.+"<i>1</i>",$Text);

$Text=preg_replace("/[u](.+"<u>1</u>",$Text);

$Text=preg_replace("/[b](.+"<b>1</b>",$Text);

$Text=preg_replace("/[fly](.+"<marquee width="98%" behavior="alternate" scrollamount="3">1</marquee>",$Text);

$Text=preg_replace("/[move](.+","<marquee width="98%" scrollamount="3">1</marquee>",$Text);

$Text=preg_replace("/[shadow=([#0-9a-z]{1,10}),([0-9]{1,3}),([0-9]{1,2})](.+?)[/shadow]/is","<table width="*"><tr><td>4</td></tr></table>",$Text);

return $Text;

}

}

希望本文所述对大家的php程序设计有所帮助。
