类和接口 php 之间的自动加载差异 [英] autoload differnece between class and interface php

问题描述

我正在寻找我遇到的以下问题.我们项目的类文件名为 logon.class.php但该类的接口文件名为 logon.interface.php

I'm searching for following issue i have. The class file names of our project are named logon.class.php But the interface file for that class is named logon.interface.php

我的问题是，当自动加载方法运行时，我应该能够检测到它是类调用还是接口调用.

My issue i have is that when the autoload method runs I should be able to detect if it is a class call or an interface call.

<?php 
function __autoload($name){
    if($name === is_class){
        include_once($name.'class.php');
    }elseif ($name === is_interface){
         include_once($name.'interface.php');
    }
}
?>

推荐答案

您可以使用 ReflectionClass::isInterface 判断类是否为接口.

You can use ReflectionClass::isInterface to determine if the class is an interface.

$reflection = new ReflectionClass($name);

if ($reflection->isInterface()){
  //Is an interface
}else{
  //Not an interface
}

在您的情况下，您可能必须首先在 $name.interface.php 和 $name.class.php 上使用 file_exist确定它们是否存在，要求存在的那个，然后检查它是否是一个接口.

In your case, you would probably have to use file_exist first on $name.interface.php and $name.class.php to determine if they exist, require the one that exists, then check if it's an interface.

但是，我认为这可能会导致问题.如果你有 MyClass.class.php 和 MyClass.interface.php 怎么办?

However, my opinion is that this might cause problems down the track. What if you have MyClass.class.php and MyClass.interface.php?
