• 禁止多余的分号，如;;;
• 禁止多余的空白行
• 禁止代码和注释之间存在空格
• 禁止空注释
• 注释中标签垂直对齐
• 注释和代码保持相同的缩进
• 命名空间前面不应该有空格
• 代码相近的赋值操作对齐
• 数组成员在单个作用域中按最小空间对齐
• PHPDoc需遵循PSR-5
• 多行注释对齐
• 强制转换和变量之间应该有一个空格
• 连接符号两边必须有一个空格
• 等号对齐、数字箭头符号对齐
• 在数组声明中，每个逗号后面必须有一个空格
• 数组使用简洁语法，方括号语法
• 数组索引必须是方括号
• 规定函数中括号的格式
• class 的 method 之间需要存在一个空行
• class 的 property 之间需要存在一个空行
• class 的 const、trait_import、case 不需要空行
• 命名空间中不得包含空格，注释
• 如需取消变量，必须使用 (null) 而非 (unset)强制类型转换
• 尽可能的使用空合并运算法
• 方法调用的参数每个逗号后必须有一个空格
