Magento 2 Coding Standards (CRITICAL)

Magento 2 编码标准（CRITICAL）

PSR-12 & Magento Standards

PSR-12 与 Magento 标准

PSR-12 Compliance: Strictly enforce PSR-12 coding standards

Magento Coding Standard: Verify compliance with

vendor/magento/magento-coding-standard/Magento2

EditorConfig: Check project's
```
.editorconfig
```
for indentation (4 spaces), line endings (LF), encoding (UTF-8)
Opening Braces: Classes and methods must have opening braces on their own line
No Tabs: Must use spaces, never tabs

PSR-12 合规性：严格执行PSR-12编码标准

Magento编码标准：验证是否符合

vendor/magento/magento-coding-standard/Magento2

规范

EditorConfig：检查项目的
```
.editorconfig
```
文件，确保缩进为4个空格、行尾为LF、编码为UTF-8
大括号规则：类和方法的左大括号必须单独占一行
禁用制表符：必须使用空格，绝对不能使用制表符

Type Safety & Modern PHP

Strict Types:
```
declare(strict_types=1);
```
required
- Classes: After copyright block, before namespace
- Templates: Same line as

!==
```
(never
```
==
```
or
```
!=
```
)

严格类型声明：必须添加
```
declare(strict_types=1);
```
- 类文件：版权声明块之后，命名空间之前
- 模板文件：与
```
<?php
```
  起始标记在同一行
类型提示：所有参数和返回值必须添加类型提示
构造函数属性提升：在合适的场景下结合
```
readonly
```
修饰符使用
严格比较：始终使用
```
===
```
和
```
!==
```
（绝对不能使用
```
==
```
或
```
!=
```
）
