php ubb代碼解析程式_PHP教程

文章給你分享一篇簡單的關於ubb代碼如何利用php來解析哦，我們主要用到了preg_replace()函數，有了其它一切都好做

代碼如下

/** +---------------------------------------------------------- * 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); $Text=preg_replace("/[pre](.+?)[/pre]/is"," \1 ",$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; }

關於preg_replace()函數文法

preg_replace函數基礎與執行個體代碼
//preg_replace ( mixed $pattern , mixed $replacement , mixed $subject [, int $limit = -1 [, int &$count ]] ) 主題為匹配搜尋模式，替換替換
/*
要搜尋的模式。它可以是一個字串或一個字串數組。

電子修飾符使preg_replace函數（）替代治療後，適當引用作為參數是php教程代碼進行替換。提示：請確保置換構成一個有效php代碼字串，否則php將抱怨在包含preg_replace函數線（）解析錯誤。

傳回值

preg_replace函數（）返回一個數組，如果這個問題的參數是一個數組或一個字串，否則。

如果找到匹配，新問題會產生，否則將返回主題不變或null如果發生錯誤。
