PHP将HTML代码转换到UBB论坛代码_PHP教程

烈16火84网(LieHuo24.Net)教17程 最近给下载栏目增设一键转帖功能，烈火下载栏目是使用DedeCMS构建的，大家都知道dede没有一键转帖功能，于是只好自己写一个，最终实现了。这里记下其中软件简介的HTML转UBB代码。

关于PHP将HTML转UBB代码的问题，笔者在网上找到几个，但都不太好用，于是自己进行了修改和整理，如您有其它需求，可在下面留言。

PHP代码：

Copy to Clipboard引用的内容：[www.bkjia.com] $intro = $liehuo-net; // 这里是你获取的变量值。
$intro = str_replace("\n",'',$intro);
$intro = preg_replace("/\]+HREF=\"([^\"]+)\"[^>]*\>(.*?)<\/a\>/i","[url=https://www.gxlcms.com/$1]$2[/url]",$intro);
$intro = preg_replace("/\]+)\"(.*?)\>(.*?)<\/font>/i","[color=$2]$4[/color]",$intro);
$intro = preg_replace("/\]+)\"(.*?)\>(.*?)<\/font>/i","[face=$2]$4[/face]",$intro);
$intro = preg_replace("/\]+)\"(.*?)\>(.*?)<\/font>/i","[size=$2]$4[/size]",$intro);
$intro = preg_replace("/\]+src=\"([^\"]+)\"[^>]*\>/i","[img]https://www.gxlcms.com/$1[/img]",$intro);
$intro = preg_replace("/\]+ALIGN=\"([^\"]+)\"[^>]*\>(.*?)<\/DIV\>/i","[align=https://www.gxlcms.com/$1]$2[/align]",$intro);
$intro = preg_replace("/\]+ALIGN=\"([^\"]+)\"[^>]*\>(.*?)<\/P\>/i","[align=https://www.gxlcms.com/$1]$2[/align]",$intro);
$intro = preg_replace("/\<([\/]?)u\>/i","[https://www.gxlcms.com/$1u]",$intro);
$intro = preg_replace("/\<([\/]?)em\>/i","[https://www.gxlcms.com/$1I]",$intro);
$intro = preg_replace("/\<([\/]?)strong\>/i","[https://www.gxlcms.com/$1b]",$intro);
$intro = preg_replace("/\<([\/]?)i\>/i","[https://www.gxlcms.com/$1i]",$intro);
echo $intro; // 最后得到UBB代码
?>

现在我们知道了HTML到UBB的转换，那么UBB是否能返回HTML呢？请参照下面的代码，网上收集的。

代码一：

Copy to Clipboard引用的内容：[www.bkjia.com] 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(
"https://www.gxlcms.com/$1",
"https://www.gxlcms.com/$1",
"https://www.gxlcms.com/$1",
"$2",
"550)this.width=500\" title=\"烈火提示：点击查看\">",
"

https://www.gxlcms.com/$1

$2

"
);
$strCodes = preg_replace($match, $replace, $strCodes);

return $strCodes ;
}
?>

代码二：
