PHP：PHP找不到在include（）脚本中定义的类

Question

I am trying to use Michelf's PHP implementation of Markdown.

I'm including his Markdown.php script with include() at the beginning of my main script, but when trying to use the class (be it for creating a new object or using a method directly), I get this:

Fatal error: Class 'Markdown' not found in [my main script]

The class Markdown is cleary defined in included Markdown.php however.

I've checked, of course, that the include works. I've tried placing Markdown.php in both my include_path and my main script's path, it doesn't change anything.

I am at a loss.

Judging by the source file , you most likely forgot to import the class before using it:

use Michelf\Markdown;

// ...

$md = new Markdown();

Alternatively, you could use the canonical name:

$md = new \Michelf\Markdown();
