本文實例講述了php實現過濾UBB代碼的類。分享給大家供大家參考。具體如下：

PHP代碼如下：

class Day{

function ubb($Text) {????? /// UBB代碼轉換

//$Text=htmlspecialchars($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;

}

}

希望本文所述對大家的php程序設計有所幫助。
