Save all programers! (sorry my "brazilian english")
I have a simple doubt, but i´m tired because i not found answers...
Why, inside a class, declarare $this variables in a format "var $varname;"
before of a constructor?
And, please, what intend the "&" signal before functions name?
I know the arguments reference methods like this:
function bla(&$reference_arg)
But what's the diference of the sintax:
function &bla(&$var)
Thanks for attention
