如何在Zend Framework中加载一个类

Question

I got a PHP library ( PHP Markdown ) in my library fold in an standard Zend Framework application. What is the best way to load the file and all it's classes to use in my models and controllers.

Structure:

library/phpMarkdown/markdown.php

Note: PHP Markdown has a really ugly structure: It's only real "API" is a simple function, not a class. So the elegant was do not work for this exact case , but regarding the question the genearl solution the correctly named files/class is also "the right answer.

Edit So much good input here, really not sure which answer I should accept! Thanks to you all!

Answer 1

The autoloader

Just instantiate the class and the autoloader should find it. If it doesn't you need to add the namespace and path.

Answer 2

If you have a class in the following tree (for exemple) : library/My/Tool.php

You will need to add this to your application.ini :

autoloaderNamespaces[] = "My_"

And then in your code you just call :

$tool = new My_Tool();

Edit :

in the file Tool.php you must follow the Zend Naming Conventions and have something like this :

<?php

class My_Tool {

}

For more informations see this : Zend Naming conventions

Answer 3

To keep it simple and just add that one file, you could put something like this in your Bootstrap.php :

 protected function _initLoad(){
        Zend_Loader::loadFile('markdown.php', '/../library');

    }

I just copied markdown.php into the application library and put this little function in the bootstrap. You could also use Zend_Loader::loadClass(); if you want.
