Detailed explanation of PHP object-oriented PSR-0 specification
PSR-0规范1.命名空间必须与绝对路径一致 2.类名首字母必须大写 3.除入口文件外,其它.php必须只有一个类。
开发符合PSR-0规范的基础框架
1.全部使用命名空间
2.所有PHP文件必须自动载入,不能有include/require
3. 单一入口
项目
目录
控制器中的index.php
<?phpnamespace App\Controller\Home;class Index{ static function test() { echo '我是控制器'; } }
Loader.php
<?php/** * User: baldy * CreateTime: 2018/2/27 下午5:27 * Description: */namespace IMooc;class Loader{ static function autoload($class) { $file = BASEDIR.'/'.str_replace('\\','/',$class).'.php'; require $file; } }
Object1.php
<?phpnamespace IMooc;class Object1{ static function test(){ echo "我是Object"; } }
index.php
<?phpdefine('BASEDIR',__DIR__); include BASEDIR . '/IMooc/Loader.php'; spl_autoload_register('\\IMooc\\Loader::autoload'); IMooc\Object1::test(); App\Controller\Home\Index::test();
结果
我是Object我是控制器

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
