文章给你分享一篇简单的关于ubb代码如何利用php来解析哦，我们主要用到了preg_replace()函数，有了其它一切都好做

代码如下

复制代码

/** +---------------------------------------------------------- * UBB 解析 +---------------------------------------------------------- * @return string +---------------------------------------------------------- */ function ubb($Text) { $Text=trim($Text); $Text=ereg_replace("n"," ",$Text); $Text=preg_replace("/\t/is"," ",$Text); $Text=preg_replace("/[hr]/is"," ",$Text); $Text=preg_replace("/[separator]/is"," ",$Text); $Text=preg_replace("/[h1](.+?)[/h1]/is"," \1 ",$Text); $Text=preg_replace("/[h2](.+?)[/h2]/is"," \1 ",$Text); $Text=preg_replace("/[h3](.+?)[/h3]/is"," \1 ",$Text); $Text=preg_replace("/[h4](.+?)[/h4]/is"," \1 ",$Text); $Text=preg_replace("/[h5](.+?)[/h5]/is"," \1 ",$Text); $Text=preg_replace("/[h6](.+?)[/h6]/is"," \1 ",$Text); $Text=preg_replace("/[center](.+?)[/center]/is","\1",$Text); //$Text=preg_replace("/[url=([^[]*)](.+?)[/url]/is","\2",$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); $Text=preg_replace("/[img](.+?)[/img]/is","",$Text); $Text=preg_replace("/[imgs(.+?)](.+?)[/img]/is","",$Text); $Text=preg_replace("/[color=(.+?)](.+?)[/color]/is","\2",$Text); $Text=preg_replace("/[colorTxt](.+?)[/colorTxt]/eis","color_txt('\1')",$Text); $Text=preg_replace("/[style=(.+?)](.+?)[/style]/is"," \2 ",$Text); $Text=preg_replace("/[size=(.+?)](.+?)[/size]/is","\2",$Text); $Text=preg_replace("/[sup](.+?)[/sup]/is","\1",$Text); $Text=preg_replace("/[sub](.+?)[/sub]/is","\1",$Text); $Text=preg_replace("/[pre](.+?)[/pre]/is"," \1 登入後複製 ",$Text); $Text=preg_replace("/[emot](.+?)[/emot]/eis","emot('\1')",$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("/[quote](.+?)[/quote]/is"," 引用: \1 ", $Text); $Text=preg_replace("/[code](.+?)[/code]/eis","highlight_code('\1')", $Text); $Text=preg_replace("/[php](.+?)[/php]/eis","highlight_code('\1')", $Text); $Text=preg_replace("/[sig](.+?)[/sig]/is"," -------------------------- \1 -------------------------- ", $Text); return $Text; }

关于preg_replace()函数语法

preg_replace函数基础与实例代码
//preg_replace ( mixed $pattern , mixed $replacement , mixed $subject [, int $limit = -1 [, int &$count ]] ) 主题为匹配搜索模式，替换替换
/*
要搜索的模式。它可以是一个字符串或一个字符串数组。

电子修饰符使preg_replace函数（）替代治疗后，适当引用作为参数是php教程代码进行替换。提示：请确保置换构成一个有效的php代码字符串，否则php将抱怨在包含preg_replace函数线（）解析错误。

返回值

preg_replace函数（）返回一个数组，如果这个问题的参数是一个数组或一个字符串，否则。

如果找到匹配，新问题会产生，否则将返回主题不变或null如果发生错误。
