一切的起点,首先要打开PHP报错

## vim php.inilog_errors = On  # 默认已开启error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT  # 默认已开启## 你也可以在php代码中 临时切换 当前处理的 PHP报错等级error_reporting ( E_ERROR  |  E_WARNING  |  E_PARSE );  # 函数返回先前的报错等级



其次,配置错误日志路径

## 我们指定php报错日志路径## vim php.inierror_log = /var/log/php_errors.log  # 需手动打开

如果没有指定php报错日志路径 , 则php的报错日志将写入 apache主机的错误日志路径中



已打开PHP报错后, 除了将报错写入日志中, 我们还能让错误信息 直接回显给浏览器输出

!! 线上部署环境下,务必关闭错误回显 !!

## vim php.inidisplay_errors = On  # 需手动打开## 你也可以在php代码中 临时切换 当前处理的 错误回显设置ini_set ( 'display_errors' ,  '1' );

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

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.

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

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

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),
