Description:
------------
Could we not use 'var' to declare variables outside of functions and have a config option or file related pragma that made not declaring a variable an error ?

Yes: there would be a problem with existing code, so why not force variable declaration iff/after a 'var' declaration is seen.

If you really want to do it properly, then we could use 'private' or 'static' to declare variables with the scope of the file that they are declared in (like in C).

The most recent bug reference that I can find for this is: 14285 (Nov 2001).

This is a MUST HAVE, it is the single most dangerous mis-feature of PHP. Don't get me wrong - I like PHP, but just hanker after perl's use strict - great at pointing out typeos.

Turn error_reporting to E_ALL, and you have exactly what you asked for, and so much more.

No, E_ALL does not do everything that I need. It will not report mistyped variables who are assigned, only those that are used. E_ALL only generates a warning when code is executed which is not useful for infrequently executed code.
