『Composer 一统天下的时代已经到来!』
——白岩松
“一个时代结束了,另一个时代开始了。”
Framework Interoperability Group(框架可互用性小组),简称 FIG,成立于 2009 年。FIG 最初由几位知名 PHP 框架开发者发起,在吸纳了许多优秀的大脑和强健的体魄后,提出了PSR-0 到 PSR-4 五套 PHP 非官方规范:
1. PSR-0 (Autoloading Standard) 自动加载标准
2. PSR-1 (Basic Coding Standard) 基础编码标准
3. PSR-2 (Coding Style Guide) 编码风格向导
4. PSR-3 (Logger Interface) 日志接口
5. PSR-4 (Improved Autoloading)自动加载优化标准
之后,在此标准之上,Composer横空出世!Composer 利用 PSR-0 和 PSR-4 以及 PHP5.3 的命名空间构造了一个繁荣的 PHP 生态系统。Composer 类似著名的 npm 和 RubyGems,给海量 PHP 包提供了一个异常方便的协作通道,Composer Hub 地址:https://packagist.org/。Composer 中文网站:http://www.phpcomposer.com/。
目前 PHP 界风头正劲的 Laravel 和 Symfony 均直接基于 Composer,大家耳熟能详著名框架 CI 和 Yii 的正开发版本CodeIgniter 3 和 Yii 2 也都基于 Composer(更新:北京时间2014年10月13日 Yii 2 已经发布)。Composer 就是 PHP 框架的未来,有了它,让 CI 的路由和 Laravel 的 Eloquent ORM 协作就会变的非常简单。
PHP 语言本身就带有强大的网络功能、文件管理功能和丰富的系统 API,Composer 也只是一段 PHP 脚本而已。可以使用
php composer.phar update
直接调用。
在合适的地方新建一个文件夹,命名为 MFFC(My First Framework based on Composer),在文件夹下新建文件 composer.json:
{ "require": { }}
命令行切换到 MFFC 目录下,运行:
composer update
稍等片刻,会出现如下文件及文件夹:
如果以上内容成功出现,恭喜你,Composer 初始化成功!
问题一:为什么一定把manager as capsule
因为命名太长,所以重命名一下,用起来方便
问题二:vendor下面得autoload.php得作用是什么,不要说自动载入,我想知道得是如何载入得
require '../vendor/autoload.php';
这个文件的代码看不到,所以我也不知道他干嘛的
问题三:bootEloquent()函数是什么作用
没看到在哪定义这个函数,所以无法判断作用
mysql+php+apache,模板用smarty好了,简单又好用。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.
