Cheers Thiago, In fact this was going to be my next question. I think I will report a documentation bug, just because, after all the discussion we had today, I realize that this is quite a common behaviour in other languages, but for somebody new to languages, being them programming or scripting ones, the fact that the $a=0 line doesn't get executed on subsequent calls isn't so obvious. In other words, from the standpoint of someone that is relatively new to the details (at least), the flow is: 'ok, I do appreciate that the engine keeps memory of the value of that variable declared as static after the function ends, but assigning a value to it at the very beginning of the function seems like the next time the function is going to be called, it will assaign that value again and again...and again'. And I guess the manual wants to be as clear as possible, considering that the examples are often 'foo 'and '$a' related :P In other words I think that it is indeed targeted to beginners as wel, isn't it? Thanks for all the valuable info btw. :) In 4/3/08 16:59, Thiago Pojda, thiago.pojda@xxxxxxxxxxxxxxxxxx ha scritto > > > -----Mensagem original----- > De: Svevo Romano [mailto:svevo@xxxxxxxxxxxxxx] > > Hi there, > > Many thanks for your answer.
