Re: Re[2]: [PHP] declaring variables in class definitions

Max, Thanks for your response. Assigning something to $d->somevar when it is not declared in the definition works fine. As far as I can tell, and from what we have found here, there is absolutly no reason whatsoever to define variables in class definitions. If someone can show me me a reason , other than a pure aesthetics, why this is nessesary I would sure like to know. If anyone could show me at least one example where not defining variables in class definitions would somehow break the class, I would like to see it. Thanks, Sam >> $d->somevar = true; >> and the next call to $d->b() will print nothing. >> But you won't be able to assign a value to $somevar, if it is not >> declared in the class. sic> This does not appear to be true.
