如何在Codeigniter框架中添加抽象类库？ [英] How do you add abstract class library in the Codeigniter framework?

问题描述

我在文件中有 libraries 文件夹中的 AbstractClass.php
$ b

I have the following code in file called AbstractClass.php in the libraries folder

abstract class AbstractClass {
  abstract protected doSomething ();
}

class ConcreteClass extends AbstractClass {
  public function doSomething () {};

}

当我尝试加载 AbstractClass 来自 controllers 如下：

When I try to load the AbstractClass from controllers as follows:

$this->load->library('AbstractClass');

我得到无法加载请求的类：AbstractClass 错误。

我做错了什么？

感谢

推荐答案

p>很显然，你不能直接加载抽象类，因为这违背了抽象类。

Well obviously you cannot load an abstract class directly as this goes against the point of an abstract class.

您可以将抽象类与另一个库一起放在一个文件中，但这是一个有点无意义，违反了一类一文件标准CI所有良好的标准）。

You can put an abstract class in a file along with another library, but that is a bit pointless and goes against the "one class one file" standard that CI (and all good standards) suggest.

您可以在库文件中包含include（）这个文件，或者设置一个__autoload（）函数。 __autoload（）的最佳位置是config.php的底部。

You can include this file with an include() in your library files, or set up an __autoload() function to do it for you. Best place for an __autoload() is the bottom of config.php.
