php ubb code parsing program_PHP tutorial

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

About preg_replace() function syntax

Preg_replace function basics and example code
//preg_replace ( mixed $pattern , mixed $replacement , mixed $subject [, int $limit = -1 [, int &$count ]] ) The subject matches the search pattern and replaces
/*
The pattern to search for. It can be a string or an array of strings.

The electron modifier enables the preg_replace() function to replace after treating the appropriate reference as argument to the PHP tutorial code. Tip: Make sure the replacement constitutes a valid PHP code string, otherwise PHP will complain about a parsing error in the line containing the preg_replace() function.

Return value

The preg_replace function() returns an array if the argument to this question is an array or a string, otherwise.

If a match is found, a new question will be generated, otherwise the topic will be returned unchanged or null if an error occurs.
