如何使用作曲家生成的类图添加不区分大小写的自动加载?

2022-01-21 00:00:00 php composer-php autoload

我有一个遗留项目，在不同情况下有声明和类使用.

I have legacy project which has declartions and class usings in different cases.

我想将源升级到现代状态.首先，我想用作曲家自动加载替换传统的自动加载.但是 composer 不提供不区分大小写的自动加载.

I want upgrade source to modern state. First I want to replace legacy autoloading by composer autoloading. But composer does not provide case insensitive autoloading.

如何使用composer classmap和insensitive autoload?

How to use composer classmap and insensitive autoload?

推荐答案

将 classmap 添加到 composer.json.

"autoload": {
    "classmap": ["folder1/", "folder2/"]
},

然后运行composer.phar dumpautoload来创建composer/autoload_classmap.php.

更改您的代码.之后

require VENDOR_PATH . '/autoload.php';

添加

$class_map = require VENDOR_PATH . '/composer/autoload_classmap.php';
$new_class_map = array();
foreach ($class_map as $class => $file)
    $new_class_map [strtolower($class)] = $file;
unset($class_map);
spl_autoload_register(function ($class)use($new_class_map)
        {
        $class = strtolower($class);
        if (isset($new_class_map[$class]))
            {
            require_once $new_class_map[$class];
            return true;
            }
        else
            return false;
        }, true, false);
unset($new_class_map);

这是我找到的最简单的方法.

This is the simplest way I have found.
