我建议调查spl_autoload。只需将正确的目录添加到您的 include_path
这样的事情可能会帮助您入门：
ini_set($your_class_dir_here .PATH_SEPERATOR. ini_get('include_path'));
您必须使用spl_autoload_register 提供您自己的自动加载器，或者将所有文件名小写。
这是我自己的一个自动加载器，它使用 php 命名空间来解决一些目录问题。
<?php
namespace Red
{
// since we don't have the Object yet as we load this file, this is the only place where this needs to be done.
require_once 'Object.php';
/**
* Loader implements a rudimentary autoloader stack.
*/
class Loader extends Object
{
/**
* @var Loader
*/
static protected $instance = null;
/**
* @var string
*/
protected $basePath;
/**
* @return Loader
*/
static public function instance()
{
if (self::$instance == null)
{
self::$instance = new self();
}
return self::$instance;
}
/**
* Initialize the autoloader. Future expansions to the
* autoloader stack should be registered in here.
*/
static public function Init()
{
spl_autoload_register(array(self::instance(), 'autoLoadInNamespace'));
}
/**
* PHP calls this method when a class is used that has not been
* defined yet.
*
* I'm returning a boolean for success which isn't required (php ignores it)
* but makes life easier when the stack grows.
*
* @param string $fullyQualifiedClassName
* @return boolean
*/
public function autoLoadInNamespace($fullyQualifiedClassName)
{
$pathParts = preg_split('/\\\\/', $fullyQualifiedClassName, -1, PREG_SPLIT_NO_EMPTY);
array_unshift($pathParts, $this->basePath);
$pathToFile = implode(DIRECTORY_SEPARATOR, $pathParts) . '.php';
if (file_exists($pathToFile))
{
require_once $pathToFile;
return true;
}
return false;
}
/**
* Constructor is protected because we don't want multiple instances
* But we do want an instance to talk to later on.
*/
protected function __construct()
{
$this->basePath = realpath(dirname(__FILE__) . DIRECTORY_SEPARATOR . '..');
}
}
}

它是 \Red 命名空间中名为 Loader 的类的一部分，并从一个简单的引导文件初始化：
<?php
// This is where the magic is prepared.
require_once implode(DIRECTORY_SEPARATOR, array(dirname(__FILE__), 'Red', 'Loader.php'));
// Initialize the autoloader, no more require_once for every class
// and everything is OOP from here on in.
Red\Loader::Init();
#EOF
