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

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

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');
    }
}
?>

解决方案

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
}

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.

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