据我所知 composer
是不能加载多vendor
目录的
但是我看到很多laravel
的workbench
都可以加载自己vendor
文件
然后通过laravel
的php artisan dump-autoload
命令加载进来. 我不是很了解laravel
的机制.
想请laravel
的高手解答下!!谢谢

首先,这个事情跟 Laravel 基本没有关系。
为什么很多人在用了 Laravel 之后发现 Laravel 有好多新特性,是因为市面上的代码、框架都 积重难返
,很多 PHP 高手都已经习惯了 PHP4 时代强大的函数和习惯用法,对 PHP 的面向对象新特性又喜欢又不想用,所以当 Taylor Otwell
这个 .NET
程序员看着 PHP 官方文档发明了 Laravel 的时候,大家都惊呆了,PHP 还能这样写!
所以并不是 Laravel 强大,而是 PHP 本身就是非常强大,只是以前没人这样用而已。其实话说回来,PHP 本身的语言特性反而是严谨古板的,没法像 Ruby 那样非常容易地就可以做出一个 DSL(领域特定语言)。
PHP 的文件加载机制是非常简单和自由的,就是
include 'fuck.php';
,背后的逻辑也是简单地把fuck.php
里的代码拷贝过来放到这里。
为了更方便地引入其他文件,PHP 引入了 自动加载
,官方文档在:http://php.net/manual/zh/language.oop5.autoload.php
自动加载的逻辑也非常简单,就是维护一张表,上面写着哪个类在哪个文件里,方便 PHP 解释器去
include
它。依赖 Composer 的系统通过include
/vendor/autoload.php
这个文件来维护这张表。这个表可以手动维护。
Laravel 同时支持 psr-0
和 psr-4
自动加载规范,他们的文档在 http://www.php-fig.org/ 右下角。
针对这个问题,是因为 workbench 这个包修改了 类->文件
的对应表,增加了几行。

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP makes it easy to create interactive web content. 1) Dynamically generate content by embedding HTML and display it in real time based on user input or database data. 2) Process form submission and generate dynamic output to ensure that htmlspecialchars is used to prevent XSS. 3) Use MySQL to create a user registration system, and use password_hash and preprocessing statements to enhance security. Mastering these techniques will improve the efficiency of web development.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

PHP remains important in modern web development, especially in content management and e-commerce platforms. 1) PHP has a rich ecosystem and strong framework support, such as Laravel and Symfony. 2) Performance optimization can be achieved through OPcache and Nginx. 3) PHP8.0 introduces JIT compiler to improve performance. 4) Cloud-native applications are deployed through Docker and Kubernetes to improve flexibility and scalability.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP and Python each have their own advantages and are suitable for different scenarios. 1.PHP is suitable for web development and provides built-in web servers and rich function libraries. 2. Python is suitable for data science and machine learning, with concise syntax and a powerful standard library. When choosing, it should be decided based on project requirements.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7
