从类中访问 Markdown PHP 函数
我正在使用 Michel Fortin 的 PHP Markdown 库。设置很简单，而且效果很好，如下所示：
include_once "markdown.php";
$my_html = Markdown($my_text);
但是，我有一个类，我想在其中传递内容并对其进行“Markdown”，如下所示：
class Test
{
public function showMarkdown ($text)
{
return Markdown($text);
}
}
显然，我的类比这个大得多，但这就是它的归结。在我的主脚本中，我这样做：
include_once "markdown.php";
$test = new Test();
echo $test->showMarkdown($text);
这会返回一个错误，指出函数“Markdown”未定义。这似乎很明显，因为它不在类内，而且我没有使用范围运算符。但是当我将 include 放入类中并使用 $this->Markdown 或 self::Markdown 时，该函数仍然未定义。我认为 Markdown 函数不能在另一个函数中定义。
那么，我该如何解决这个问题呢？我需要执行包含操作，它会加载 Markdown 函数（及其系列的其余部分），但我希望能够在我的类中使用它。
感谢您的回答/想法。
I'm using the Markdown library for PHP by Michel Fortin. Setup is easy and it works great like this:
include_once "markdown.php";
$my_html = Markdown($my_text);
However, I have a class in which I want to pass stuff and 'Markdown' it, like so:
class Test
{
public function showMarkdown ($text)
{
return Markdown($text);
}
}
Obviously, my class is much larger than this, but this is what it boils down to. In my main script I do:
include_once "markdown.php";
$test = new Test();
echo $test->showMarkdown($text);
This returns an error, saying the function 'Markdown' is undefined. That seems obvious, because it's not within the class and I haven't used a scope operator. But when I put the include inside my class and use $this->Markdown or self::Markdown the function is still undefined. I figured that the Markdown function can't be defined inside another function.
So, how can I solve this? I need to do the include, which loads the Markdown function (and the rest of its family) but I want to be able to use it from within my classes.
Thanks for your answers/ideas.

您的示例代码调用一个名为
Markdown的免费函数（可能是在markdown.php中定义的）。您只需将包含内容与您的Test类放在同一文件中即可。执行此操作后，您仍然会将
Markdown作为自由函数调用，而不是作为实例 ($this->Markdown) 或静态 (self:: Markdown) 方法。Your example code calls a free function called
Markdown(which presumably is defined inmarkdown.php). You simply need to put the include in the same file as yourTestclass.After doing this, you will still call
Markdownas a free function, and not as an instance ($this->Markdown) or static (self::Markdown) method.写
