Re: [PHP-DEV] Variable Scope

[LingWitt]

That part of the for loop is inherently declaratory. As a result, the 
interpreter should add any variables in that portion to the new symbol 
table of that for loop. Any most other languages, that portion of the 
for loop creates variables specifically in the scope of the for loop. 
Other variables of the same name are masked. Its a matter of function. 
If you don't change it, so what. But completeness of logic is the 
hallmark of computing. That's what separates the true masterpieces from 
the crap, the Apples from the Microsofts.

Its not a matter of loose typing. Its a matter of the function of the
first part of the for loop construct. It is used to declare (or
"create") variables for use in the scope of the for loop. Its this way
in virtually every language. Moreover, with the current 
implementation,
the part of the for loop of which I speak could be left out without
trouble. Its unnecessary. Furthermore, a new implementation should not
affect old code.

around.  This will never ever change in PHP.
