><P
> Estas palavras tem um significado especial no PHP. Algumas delas representam coisas
que parecem funções, algumas parecem constantes mas na verdade não o são
realmente: elas são construtores de linguagem. Você não pode usar nenhuma
das seguintes palavras como constantes, nomes de classes, de funções ou de métodos.
Utilizar como nome de variáveis geralmente não causa erros, mas pode levar a confusão.
