Laravel 源码学习系列一（composer流程） - 可能是最易懂算全面的composer教程

composer 简单基础介绍

# 在当前目录初始化一个composer.json，按照提示一步步填写即可，会在当前目录生成文件
composer init

# 根据当前composer.json 生成依赖关系，默认安装到vendor
composer install

# 在当前项目引入特定的依赖包(xxx/xxx)
composer require xxx/xxx 

# 从dist安装，用特定的包(xxx/xxx)创建项目
composer create-project --prefer-dist xxx/xxx 你的项目目录 2.2.*

# 更新某个依赖包，并更新composer.lock
composer update xxx/xxx

# 该操作会升级你项目所有可能的依赖包，并更新composer.lock **小心操作**
composer update

# 更新composer版本
composer self-update

#优化一下自动加载
composer dump-autoload --optimize

composer 版本介绍

[国内中文翻译版本](http://docs.phpcomposer.com/01-basic-usage.html#Package-Versions)
[查看官方的版本控制介绍](https://getcomposer.org/doc/articles/versions.md)

composer 加速

# 全局配置文件（推荐方式）
composer config -g repo.packagist composer https://packagist.phpcomposer.com

# 当前项目
composer config repo.packagist composer https://packagist.phpcomposer.com
# 上述命令将会在当前项目中的 composer.json 文件的末尾自动添加镜像的配置信息（你也可以自己手工添加）：
"repositories": {
    "packagist": {
        "type": "composer",
        "url": "https://packagist.phpcomposer.com"
    }
}

composer 自动加载流程

composer 目录结构

composer 加载流程

1. 项目引入composer加载文件autoload.php

require __DIR__.'/../vendor/autoload.php';

2. composer引入自身的autoload_real.php;

require_once __DIR__ . '/composer/autoload_real.php';

return ComposerAutoloaderInit0726b6b85af134cab7b1acd212d59852::getLoader();

3. 获取加载

public static function getLoader()
{
    if (null !== self::$loader) {
        return self::$loader;
    }
    
    //注册loadClassLoader函数到SPL __autoload函数队列中
    spl_autoload_register(array('ComposerAutoloaderInit0726b6b85af134cab7b1acd212d59852', 'loadClassLoader'), true, true);
    //自动加载并实例化$loader
    self::$loader = $loader = new \Composer\Autoload\ClassLoader();
    //注销loadClassLoader
    spl_autoload_unregister(array('ComposerAutoloaderInit0726b6b85af134cab7b1acd212d59852', 'loadClassLoader'));

    $useStaticLoader = PHP_VERSION_ID >= 50600 && !defined('HHVM_VERSION') && (!function_exists('zend_loader_file_encoded') || !zend_loader_file_encoded());
    if ($useStaticLoader) {
    
        //使用已经静态编译的所有加载配置
        require_once __DIR__ . '/autoload_static.php';

        //通过getInitializer方法把autoload_static的参数赋值给$loader加载器实例
        call_user_func(\Composer\Autoload\ComposerStaticInit0726b6b85af134cab7b1acd212d59852::getInitializer($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) {
            $loader->addClassMap($classMap);
        }
    }

    //注册自动加载函数到SPL __autoload函数队列中，注册到了$loader->loadClass方法
    $loader->register(true);


    //以下是始终记载files参数设置的所有文件，所以files配置的不是按需加载是都直接加载引入
    if ($useStaticLoader) {
        $includeFiles = Composer\Autoload\ComposerStaticInit0726b6b85af134cab7b1acd212d59852::$files;
    } else {
        $includeFiles = require __DIR__ . '/autoload_files.php';
    }
    foreach ($includeFiles as $fileIdentifier => $file) {
        composerRequire0726b6b85af134cab7b1acd212d59852($fileIdentifier, $file);
    }

    return $loader;
}

composer 自动加载识别判断代码

public function loadClass($class)
{
    //根据类名查找文件所在位置
    if ($file = $this->findFile($class)) {
        //引入文件
        includeFile($file);

        return true;
    }
}
public function findFile($class)
{
    // class map lookup
    if (isset($this->classMap[$class])) {
        return $this->classMap[$class];
    }
    if ($this->classMapAuthoritative || isset($this->missingClasses[$class])) {
        return false;
    }
    if (null !== $this->apcuPrefix) {
        $file = apcu_fetch($this->apcuPrefix.$class, $hit);
        if ($hit) {
            return $file;
        }
    }

    $file = $this->findFileWithExtension($class, '.php');

    // Search for Hack files if we are running on HHVM
    if (false === $file && defined('HHVM_VERSION')) {
        $file = $this->findFileWithExtension($class, '.hh');
    }

    if (null !== $this->apcuPrefix) {
        apcu_add($this->apcuPrefix.$class, $file);
    }

    if (false === $file) {
        // Remember that this class does not exist.
        $this->missingClasses[$class] = true;
    }

    return $file;
}

private function findFileWithExtension($class, $ext)
{
    // PSR-4 lookup
    $logicalPathPsr4 = strtr($class, '\\', DIRECTORY_SEPARATOR) . $ext;

    //取得命名空间的首字母
    $first = $class[0];
    //如果存在于首字母的配置，直接循环判断找到文件并返回
    if (isset($this->prefixLengthsPsr4[$first])) {
        foreach ($this->prefixLengthsPsr4[$first] as $prefix => $length) {
            if (0 === strpos($class, $prefix)) {
                foreach ($this->prefixDirsPsr4[$prefix] as $dir) {
                    if (file_exists($file = $dir . DIRECTORY_SEPARATOR . substr($logicalPathPsr4, $length))) {
                        return $file;
                    }
                }
            }
        }
    }

    // PSR-4 fallback dirs
    foreach ($this->fallbackDirsPsr4 as $dir) {
        if (file_exists($file = $dir . DIRECTORY_SEPARATOR . $logicalPathPsr4)) {
            return $file;
        }
    }

    // PSR-0 lookup
    if (false !== $pos = strrpos($class, '\\')) {
        // namespaced class name
        $logicalPathPsr0 = substr($logicalPathPsr4, 0, $pos + 1)
            . strtr(substr($logicalPathPsr4, $pos + 1), '_', DIRECTORY_SEPARATOR);
    } else {
        // PEAR-like class name
        $logicalPathPsr0 = strtr($class, '_', DIRECTORY_SEPARATOR) . $ext;
    }

    if (isset($this->prefixesPsr0[$first])) {
        foreach ($this->prefixesPsr0[$first] as $prefix => $dirs) {
            if (0 === strpos($class, $prefix)) {
                foreach ($dirs as $dir) {
                    if (file_exists($file = $dir . DIRECTORY_SEPARATOR . $logicalPathPsr0)) {
                        return $file;
                    }
                }
            }
        }
    }

    // PSR-0 fallback dirs
    foreach ($this->fallbackDirsPsr0 as $dir) {
        if (file_exists($file = $dir . DIRECTORY_SEPARATOR . $logicalPathPsr0)) {
            return $file;
        }
    }

    // PSR-0 include paths.
    if ($this->useIncludePath && $file = stream_resolve_include_path($logicalPathPsr0)) {
        return $file;
    }

    return false;
}

加载引入流程到此，你的项目主要是通过composer注册过的加载配置类，都会直接可以操作，无法再手动引入

部分结构源码

autoload_classmap.php - [composer.json->autoload.classmap]

# 这个 map 是经过扫描指定目录（同样支持直接精确到文件）中所有的 .php 和 .inc 文件里内置的类而得到的
example: "classmap": ["src/", "lib/", "Something.php"]
 $baseDir . '/app/Console/Kernel.php',
    'App\\Exceptions\\Handler' => $baseDir . '/app/Exceptions/Handler.php',
    'App\\Http\\Controllers\\ArticlesController' => $baseDir . '/app/Http/Controllers/ArticlesController.php',
    'Illuminate\\Auth\\Access\\AuthorizationException' => $vendorDir . '/laravel/framework/src/Illuminate/Auth/Access/AuthorizationException.php',
    'Illuminate\\Auth\\Access\\Gate' => $vendorDir . '/laravel/framework/src/Illuminate/Auth/Access/Gate.php',
    ...
);

autoload_files.php - [composer.json->autoload.files] 该配置下的文件每次都会直接加载

example: "files": ["src/MyLibrary/functions.php"]
 $vendorDir . '/symfony/polyfill-mbstring/bootstrap.php',
    '667aeda72477189d0494fecd327c3641' => $vendorDir . '/symfony/var-dumper/Resources/functions/dump.php',
