PHP中使用Composer进行依赖包管理，下载的包都放入了vendor文件夹，但是我们实例化一个类时，这个类是怎么加载进来的呢？
可以先看一下 PSR4 https://ibaiyang.github.io/blog/php/2022/04/03/PHP中PSR规范.html#psr-4-自动加载规范 。
还有《深入理解Yii2.0 类自动加载机制》 https://ibaiyang.github.io/blog/yii2/2019/06/24/深入理解Yii2.0-类自动加载机制.html 。
这个也是 Composer 下载依赖包后自动加载的逻辑分析。
一般在项目入口文件 index.php中我们都有一行：
require __DIR__ . '/../vendor/autoload.php';
这个文件是关键，autoload.php 的文件内容：
<?php
// autoload.php @generated by Composer
require_once __DIR__ . '/composer/autoload_real.php';
return ComposerAutoloaderInit82c3996fbc74c498b11153bcc8cd8e49::getLoader();
autoload.php这个文件是Composer生成和更新的，在 vendor 根文件夹下。 下面其他文件在 vendor/composer 文件夹下。
autoload_real.php
看下 autoload_real.php 的文件内容：
<?php
// autoload_real.php @generated by Composer
class ComposerAutoloaderInit82c3996fbc74c498b11153bcc8cd8e49
{
private static $loader;
public static function loadClassLoader($class)
{
if ('Composer\Autoload\ClassLoader' === $class) {
require __DIR__ . '/ClassLoader.php';
}
}
public static function getLoader()
{
if (null !== self::$loader) {
return self::$loader;
}
spl_autoload_register(array('ComposerAutoloaderInit82c3996fbc74c498b11153bcc8cd8e49', 'loadClassLoader'), true, true);
self::$loader = $loader = new \Composer\Autoload\ClassLoader();
spl_autoload_unregister(array('ComposerAutoloaderInit82c3996fbc74c498b11153bcc8cd8e49', 'loadClassLoader'));
$useStaticLoader = PHP_VERSION_ID >= 50600 && !defined('HHVM_VERSION') && (!function_exists('zend_loader_file_encoded') || !zend_loader_file_encoded());
if ($useStaticLoader) {
require_once __DIR__ . '/autoload_static.php';
call_user_func(\Composer\Autoload\ComposerStaticInit82c3996fbc74c498b11153bcc8cd8e49::getInitializer($loader));
} else {
$map = require __DIR__ . '/autoload_namespaces.php';
foreach ($map as $namespace => $path) {
$loader->set($namespace, $path);
}
$map = require __DIR__ . '/autoload_psr4.php';
foreach ($map as $namespace => $path) {
$loader->setPsr4($namespace, $path);
}
$classMap = require __DIR__ . '/autoload_classmap.php';
if ($classMap) {

}
}

}
foreach ($includeFiles as $fileIdentifier => $file) {
