thinkphp初始化线路

php

<?php
// [ 应用入口文件 ]

namespace think;

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

// 执行HTTP应用并响应
$http = (new App())->http;

$response = $http->run();

$response->send();

$http->end($response);

第一步

php

//在入口文件中查看文件加载情况
require __DIR__ . '/../vendor/autoload.php';
dump(get_included_files());//获取取加载的文件信息
//$array=[
//  0 => "F:\thinkphpsource\public\router.php",
//  1 => "F:\thinkphpsource\public\index.php",
//  2 => "F:\thinkphpsource\vendor\autoload.php",
//  3 => "F:\thinkphpsource\vendor\composer\autoload_real.php",
//  4 => "F:\thinkphpsource\vendor\composer\platform_check.php",
 // 5 => "F:\thinkphpsource\vendor\composer\ClassLoader.php",
 // 6 => "F:\thinkphpsource\vendor\composer\autoload_static.php",
//  7 => "F:\thinkphpsource\vendor\topthink\think-helper\src\helper.php",
 // 8 => "F:\thinkphpsource\vendor\topthink\think-orm\stubs\load_stubs.php",
 // 9 => "F:\thinkphpsource\vendor\topthink\framework\src\think\Exception.php",
 // 10 => "F:\thinkphpsource\vendor\topthink\framework\src\think\Facade.php",
 // 11 => "F:\thinkphpsource\vendor\symfony\polyfill-mbstring\bootstrap.php",
//  12 => "F:\thinkphpsource\vendor\symfony\polyfill-php72\bootstrap.php",
//  13 => "F:\thinkphpsource\vendor\symfony\polyfill-php80\bootstrap.php",
//  14 => "F:\thinkphpsource\vendor\symfony\var-dumper\Resources\functions\dump.php",
//]

第二步

php

require __DIR__ . '/../vendor/autoload.php';
new App();
dump(get_included_files());
//此实例化增加了车个文件
//$array =[
//  15 => "F:\thinkphpsource\vendor\topthink\framework\src\think\App.php",
//  16 => "F:\thinkphpsource\vendor\topthink\framework\src\think\Container.php",
//  17 => "F:\thinkphpsource\vendor\psr\container\src\ContainerInterface.php",
//  18 => "F:\thinkphpsource\app\provider.php",
//]

new App();实例化增加的文件看，使用了topthink\framework\src\think\App.php类，然而App类是继承Container.php，Container.php使用了prs里面的ContainerInterface.php这个接口，查看App.php类的信息

php

 public function __construct(string $rootPath = '')
    {
        $this->thinkPath   = dirname(__DIR__) . DIRECTORY_SEPARATOR;
        $this->rootPath    = $rootPath ? rtrim($rootPath, DIRECTORY_SEPARATOR) . DIRECTORY_SEPARATOR : $this->getDefaultRootPath();
        $this->appPath     = $this->rootPath . 'app' . DIRECTORY_SEPARATOR;
        $this->runtimePath = $this->rootPath . 'runtime' . DIRECTORY_SEPARATOR;
        //此函数加载app\provider.php文件
        if (is_file($this->appPath . 'provider.php')) {
            $this->bind(include $this->appPath . 'provider.php');
        }

        static::setInstance($this);

        $this->instance('app', $this);
        $this->instance('think\Container', $this);
    }

第三步

$http = (new App())->http;

$response = $http->run();
dump(get_included_files());

可以根据文件的加载情况大致熟悉一下流程
