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

/**

* @return string
+----------------------------------------------------------
*/
function ubb($Text) {
$Text=trim($Text);
$Text=ereg_replace("n","<br>",$Text);
$Text=preg_replace("/t/is"," ",$Text);
$Text=preg_replace("/[hr]/is","<hr>",$Text);
$Text=preg_replace("/[separator]/is","<br/>",$Text);
$Text=preg_replace("/[h1](.+?)[/h1]/is","<h1>1</h1>",$Text);
$Text=preg_replace("/[h2](.+?)[/h2]/is","<h2>1</h2>",$Text);
$Text=preg_replace("/[h3](.+?)[/h3]/is","<h3>1</h3>",$Text);
$Text=preg_replace("/[h4](.+?)[/h4]/is","<h4>1</h4>",$Text);
$Text=preg_replace("/[h5](.+?)[/h5]/is","<h5>1</h5>",$Text);
$Text=preg_replace("/[h6](.+?)[/h6]/is","<h6>1</h6>",$Text);
$Text=preg_replace("/[center](.+?)[/center]/is","<center>1</center>",$Text);
//$Text=preg_replace("/[url=([^[]*)](.+?)[/url]/is","<a href=1 target='_blank'>2</a>",$Text);
$Text=preg_replace("/[url](.+?)[/url]/is","<a href="1" target='_blank'>1</a>",$Text);
$Text=preg_replace("/[url=(http://.+?)](.+?)[/url]/is","<a href='1' target='_blank'>2</a>",$Text);
$Text=preg_replace("/[url=(.+?)](.+?)[/url]/is","<a href=1>2</a>",$Text);
$Text=preg_replace("/[img](.+?)[/img]/is","<img src=1>",$Text);
$Text=preg_replace("/[imgs(.+?)](.+?)[/img]/is","<img 1 src=2>",$Text);
$Text=preg_replace("/[color=(.+?)](.+?)[/color]/is","<font color=1>2</font>",$Text);
$Text=preg_replace("/[colorTxt](.+?)[/colorTxt]/eis","color_txt('1')",$Text);
$Text=preg_replace("/[style=(.+?)](.+?)[/style]/is","<div class='1'>2</div>",$Text);
$Text=preg_replace("/[size=(.+?)](.+?)[/size]/is","<font size=1>2</font>",$Text);
$Text=preg_replace("/[sup](.+?)[/sup]/is","<sup>1</sup>",$Text);
$Text=preg_replace("/[sub](.+?)[/sub]/is","<sub>1</sub>",$Text);
$Text=preg_replace("/[pre](.+?)[/pre]/is","<pre>1</pre>",$Text);
$Text=preg_replace("/[emot](.+?)[/emot]/eis","emot('1')",$Text);
$Text=preg_replace("/[email](.+?)[/email]/is","<a href='mailto:1'>1</a>",$Text);
$Text=preg_replace("/[i](.+?)[/i]/is","<i>1</i>",$Text);
$Text=preg_replace("/[u](.+?)[/u]/is","<u>1</u>",$Text);
$Text=preg_replace("/[b](.+?)[/b]/is","<b>1</b>",$Text);
$Text=preg_replace("/[quote](.+?)[/quote]/is","<blockquote>引用:<div style='border:1px solid silver;background:#EFFFDF;color:#393939;padding:5px' >1</div></blockquote>", $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","<div style='text-align: left; color: darkgreen; margin-left: 5%'><br><br>--------------------------<br>1<br>--------------------------</div>", $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。
