I misexplain myself I think..
What I'm looking for is : a function that will :
1- check if the $variable exist (isset)
2- return the $variable if isset
3- return something (false) if is not set
that way, you don't get undefined variable call.
Those that function already exist in cakePHP, I've seen it in some CMS
and that was pretty useful.
