如何让PHP检测段落并为HTML输出添加和解析
标记?
我正在制作一个支持bbcode的博客,但我仍然缺少博客帖子的HTML输出中的
标签。如何在其输出上进行PHP检测并添加
标记?
我当前有这个代码只解析一些基本的bbcode和GeSHi代码:
<?php
function code($match) {
require_once './class/geshi/geshi.php';
$geshi = new GeSHi($match[2], $match[1]);
return $geshi->parse_code();
}
function bbcode($input) {
$input = strip_tags($input);
$input = htmlentities($input);
$bbcodes = array(
"/\[b\](.*?)\[\/b\]/is" => "<b>$1</b>",
"/\[u\](.*?)\[\/u\]/" => "<u>$1</u>",
"/\[i\](.*?)\[\/i\]/" => "<i>$1</i>",
"/\[d\](.*?)\[\/d\]/" => "<del>$1</del>",
"/\[url=(.*?)\](.*?)\[\/url\]/" => "<a href='$1'>$2</a>"
);
$input = preg_replace(array_keys($bbcodes), array_values($bbcodes), $input);
//Check for code and add GeSHi:
$input = preg_replace_callback('~\[code=(.*?)\](.*?)\[\/code\]~is', 'code', $input);
return $input;
}
?>
如果用户在textarea中提交以下示例:
This is [b]bold and [i]italic[/i][/b].
This is some [u]PHP[/u] code:
[code=php]
echo 'Hello world!';
[/code]
That's all folk!
HTML输出是:
This is <b>bold and <i>italic</i></b>.
This is some <u>PHP</u> code:
<pre class="php" style="font-family:monospace;">
<span style="color: #b1b100;">echo</span> <span style="color: #0000ff;">'Hello world!'</span><span style="color: #339933;">;</span>
</pre>
That's all folk!
...没有p标签。那么如何添加此功能呢?
