PHP Markdown 将最后一块内容标记为 h3

Question

我使用 PHP Markdown（版本 1.0.1n，2009 年 10 月更新）来显示文本以 Markdown 格式保存到数据库。我遇到了一个奇怪的问题，它将每个条目的最后一块标记为 H3。但是，当我搜索 markdown.php 文件时，没有任何 H3 实例。

以下是我的数据库中的两段文本：

Since its launch, major CPG brands, endemic as well as non-endemic, have flocked to retail websites to reach consumers deep in the purchase funnel through shopping media. In this session, you will hear about:

- The prioritization of shopping media for CPG brands.

- A case study of brands on Target.com on how this retailer (and others) have introduced a new channel for brand marketers to engage consumers where they are making the majority of purchase decisions: online.

- How CPG brands are leveraging real-time data from shopping media to capture consumer insights and market trends.

在这一段中，它正确地标记了 LI 项目，但在最终的 LI 中，它将实际文本标记为 H3。

Beyond the actual money she saves, this consumer is both empowered and psychologically gratified by getting the best value on her everyday purchases. It is essential for both marketers and retailers to focus on what motivates and activates this consumer. 

Diane Oshin will share insights on what influences her shopping behavior and then identify specific tools that activate her to buy.

在这个例子中，以 Diane Oshin 开头的整个段落都被标记为 H3。

这是真正奇怪的事情：当我查看源代码时，它们都被正确标记；只有在使用 Inspect Element 时我才能看到 H3。然而，在实际显示中很明显，H3标签正在被应用：

有人可以帮我吗？

更新

根据下面的评论，我查找了 H 标签的实例。我找到了这些函数，但不知道这是否是导致问题的原因。它们是整个文件中唯一似乎正在创建任何类型的标头标记的位置。

function doHeaders($text) {
        # Setext-style headers:
        #     Header 1
        #     ========
        #  
        #     Header 2
        #     --------
        #
        $text = preg_replace_callback('{ ^(.+?)[ ]*\n(=+|-+)[ ]*\n+ }mx',
            array(&$this, '_doHeaders_callback_setext'), $text);

        # atx-style headers:
        #   # Header 1
        #   ## Header 2
        #   ## Header 2 with closing hashes ##
        #   ...
        #   ###### Header 6
        #
        $text = preg_replace_callback('{
                ^(\#{1,6})  # $1 = string of #\'s
                [ ]*
                (.+?)       # $2 = Header text
                [ ]*
                \#*         # optional closing #\'s (not counted)
                \n+
            }xm',
            array(&$this, '_doHeaders_callback_atx'), $text);

        return $text;
    }
    function _doHeaders_callback_setext($matches) {
        # Terrible hack to check we haven't found an empty list item.
        if ($matches[2] == '-' && preg_match('{^-(?: |$)}', $matches[1]))
            return $matches[0];

        $level = $matches[2]{0} == '=' ? 1 : 2;
        $block = "<h$level>".$this->runSpanGamut($matches[1])."</h$level>";
        return "\n" . $this->hashBlock($block) . "\n\n";
    }
    function _doHeaders_callback_atx($matches) {
        $level = strlen($matches[1]);
        $block = "<h$level>".$this->runSpanGamut($matches[2])."</h$level>";
        return "\n" . $this->hashBlock($block) . "\n\n";
    }

我无法用您提供的版本重现您所描述的内容：

<?php
include(__DIR__.'/php-markdown/markdown.php');


$testText = 'Since its launch, major CPG brands, endemic as well as non-endemic, have flocked to retail websites to reach consumers deep in the purchase funnel through shopping media. In this session, you will hear about:

- The prioritization of shopping media for CPG brands.

- A case study of brands on Target.com on how this retailer (and others) have introduced a new channel for brand marketers to engage consumers where they are making the majority of purchase decisions: online.

- How CPG brands are leveraging real-time data from shopping media to capture consumer insights and market trends.
';

$resultText = Markdown($testText);

var_dump($resultText);

输出看起来与您所期望的相当，

string(649) "<p>Since its launch, major CPG brands, endemic as well as non-endemic, have flocked to retail websites to reach consumers deep in the purchase funnel through shopping media. In this session, you will hear about:</p>

<ul>
<li><p>The prioritization of shopping media for CPG brands.</p></li>
<li><p>A case study of brands on Target.com on how this retailer (and others) have introduced a new channel for brand marketers to engage consumers where they are making the majority of purchase decisions: online.</p></li>
<li><p>How CPG brands are leveraging real-time data from shopping media to capture consumer insights and market trends.</p></li>
</ul>

我假设在数据进入降价解析器之前或之后有其他东西篡改了数据。但根据数据，Markdown 解析器不会创建

标签。你必须看看其他地方:(
