在PHP里面所要遵守的命名约定
1. 网站建设www.ucantech.com类文件都是以“.class.php“为后缀,且类文件名只允许字母,使用驼峰法命名,并且首字母大写,例如:DbMysql.class.php 。
2. 配置和函数等其他类库文件之外的文件一般是分别以“.inc.php“和”.php“为后缀,且文件名命名使用小写字母和下划线的方式,多个单词之间以下划线分隔,例如config.inc.php , common.php,install_function.php 。
3. 确保文件的命名和调用大小写一致,是由于在类Unix系统上面,对大小写是敏感的。
4. 类名和文件名一致(包括上面说的大小写一致),且类名只允许字母,例如 UserAction类的文件命名是UserAction.class.php, InfoModel类的文件名是InfoModel.class.php 。
5. 控制器类以Action为后缀,例如 UserAction、InfoAction ,模型类以Model为后缀,例如UserModel、InfoModel ,其他类也分别以相应分类为后缀,例如Service 、Widget。
6. 方法名只允许由字母组成,下划线是不允许的,首字母要小写,其后每个单词首字母要大写,即所谓的 “驼峰法命名” 规则,且越详细越好,应该能够描述清楚该方法的功能,例如switchModel、findPage。
7. 属性的命名只允许由字母组成,下划线是不允许的,首字母要小写,其后每个单词首字母要大写,即所谓的 “驼峰法命名” 规则,例如tablePrefix、tableName 。(fblww-1231)

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),
