這篇文章主要介紹了php實現過濾UBB代碼的類,涉及php正則表達式的操作技巧,具有一定參考借鑒價值,需要的朋友可以參考下

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：

代碼如下:

class Day{

function ubb($Text) { /// UBB代碼轉換

//$Text=htmlspecialchars($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=\"" target=\"new\"><u>\\1</u></a>",$Text);

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

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

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

$Text=preg_replace("/\[color=(.+?)\](.+?)\[\/color\]/is","<font color=\");

$Text=preg_replace("/\[font=(.+?)\](.+?)\[\/font\]/is","<font face=\");

$Text=preg_replace("/\[email=(.+?)\](.+?)\[\/email\]/is","<a href=\");

$Text=preg_replace("/\[email\](.+?)\[\/email\]/is","<a href=\");

$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;

}

}
