PHP 將 HTML 代碼 轉換到 UBB 論壇代碼

烈16火84網(LieHuo24.Net)教17程 最近給下載欄目增設一鍵轉帖功能，烈火下載欄目是使用DedeCMS構建的，大家都知道dede沒有一鍵轉帖功能，於是只好自己寫一個，最終實現了。這裡記下其中軟件簡介的HTML轉UBB代碼。

一鍵轉帖演示：

關於PHP將HTML轉UBB代碼的問題，筆者在網上找到幾個，但都不太好用，於是自己進行了修改和整理，如您有其它需求，可在下面留言。

PHP代碼：

Copy to Clipboard引用的內容：[www.bkjia.com] <?php
$intro = $liehuo-net; // 這裡是你獲取的變量值。
$intro = str_replace("\n",'',$intro);
$intro = preg_replace("/\<A[^>]+HREF=\"([^\"]+)\"[^>]*\>(.*?)<\/a\>/i","[url=$1]$2[/url]",$intro);
$intro = preg_replace("/\<font(.*?)color=\"#([^ >]+)\"(.*?)\>(.*?)<\/font>/i","<font$1$3>[color=$2]$4[/color]</font>",$intro);
$intro = preg_replace("/\<font(.*?)face=\"([^ >]+)\"(.*?)\>(.*?)<\/font>/i","<font$1$3>[face=$2]$4[/face]</font>",$intro);
$intro = preg_replace("/\<font(.*?)size=\"([^ >]+)\"(.*?)\>(.*?)<\/font>/i","[size=$2]$4[/size]",$intro);
$intro = preg_replace("/\<img[^>]+src=\"([^\"]+)\"[^>]*\>/i","[img]$1[/img]",$intro);
$intro = preg_replace("/\<DIV[^>]+ALIGN=\"([^\"]+)\"[^>]*\>(.*?)<\/DIV\>/i","[align=$1]$2[/align]",$intro);
$intro = preg_replace("/\<P[^>]+ALIGN=\"([^\"]+)\"[^>]*\>(.*?)<\/P\>/i","[align=$1]$2[/align]",$intro);
$intro = preg_replace("/\<([\/]?)u\>/i","[$1u]",$intro);
$intro = preg_replace("/\<([\/]?)em\>/i","[$1I]",$intro);
$intro = preg_replace("/\<([\/]?)strong\>/i","[$1b]",$intro);
$intro = preg_replace("/\<([\/]?)i\>/i","[$1i]",$intro);
echo $intro; // 最後得到UBB代碼
?>

現在我們知道了HTML到UBB的轉換，那麼UBB是否能返回HTML呢？請參照下面的代碼，網上收集的。

代碼一：

Copy to Clipboard引用的內容：[www.bkjia.com] <?php
function ubb2html($strCodes) {
$match = array(
"%\[b\](.*?)\[\/b\]%si",
"%\[center\](.*?)\[\/center\]%si",
"%\[url\](.*?)\[\/url\]%si",
"%\[url=(.*?)\](.*?)\[\/url\]%si",
"%\[img\](.*?)\[\/img\]%si",
"%\[fieldset=(.*?)\](.*?)\[\/fieldset\]%si"

);
$replace = array(
"<b>$1</b>",
"<center>$1</center>",
"<a href=\"$1\" target=_blank>$1</a>",
"<a href=\"$1\" target=_blank>$2</a>",
"<a href=\"$1\" target=\"_blank\"><img src=\"$1\" title="烈火提示:點擊查看" border=\"0\" onload=\"javascript:if(this.width>550)this.width=500\" title=\"烈火提示：點擊查看\"></a>",
"<fieldset><legend>$1</legend><blockquote>$2</blockquote></fieldset>"
);
$strCodes = preg_replace($match, $replace, $strCodes);

return $strCodes ;
}
?>

代碼二：
