PHP的命名空间是否区分大小写?

结论:不区分大小写,与类名一样(不区分大小写)。

不区分大小写的包括

  1. 函数名
  2. 方法名
  3. 类名
  4. 控制语句(if, else, for, while, foreach)
  5. null,true, false
  6. 魔术变量
  7. 变量强制类型转换(int, string, double, boolean, object, array)
  8. 语言结构(echo, require, include)

  1. it is usually good form to call functions as they appear in their declaration.
  2. always use same cases when reference back to either variables(its\' mandatory) or functions(its\' optional, but recommended).

notice: array keys
