다음은 PHP에서 기선언된 식별자 목록이다. 이 식별자 목록 중 어느것도 스크립트에서 식별자로 사용될수 없다. 이 목록은 키워드와 기선언 변수, 상수, 클래스 명도 포함한다. 이 목록은 철저하지도 완벽하지도 않다.

[Editorial note: parent and self are reserved class names. Functions and constants with their names can be declared, but not userspace classes]

true, false and null are not listed because they are globally-defined constants, not reserved words.

No idea about parent or self, though.

Naming a PHP5 class "variant" (with a constructor called the same) and then making an instance of it using __autoload triggers an error which disappears as soon as the name is changed. This should mean that "variant" is also a reserved word.

Two things:

1. It would be nice for this list to differentiate those reserved words, which are language constructs used *with* parentheses (isset, unset, empty, eval, exit, die, ...) and those rather to be used *without* parentheses (all includes, echo, print, return, ...?)

This would really help define some common coding styles...

2. Do you write NULL, TRUE, FALSE or null, true, false? (I find CAPITAL letters better, however typing them can be annoying so I stick with using all lowercase letters, but what's the standard?)

I don't see the boolean constants 'true' and 'false' listed among the reserved words/keywords/constants.
