Re: OUR declaration

I usually use our in preference to use vars because it allows a declaration and assignment in one go:

our $globalvar = 10;

For global variables, I usually use our in preference to my because it doesn't create closures within subs, which can cause problems under mod_perl.

When using `our` as an alternative to `my` in pseudo-CGI scripts that'll be running under mod_perl I recommend getting into the habit of using `local our` so that you get a pseudo "global destruction" at the end of the pseudo-CGI script. Otherwise, if the declaration doesn't initialise, the value from a previous execution of the script may persist and also if there are any destruction side effects (like closing files) these may get deferred.

I don't reccommend using our "as an alternative to my" under mod_perl. They don't do the same thing, and mod_perl doesn't change that. If you are using "our" because your code has unintentional closures around "my" variables that showed up when you used mod_perl, you should really change your code to fix this problem. It can bite you in other ways, and "local our" is a pretty nasty construct.	[reply]

The mod_perl Reference recommends exactly that. While there are differences between using `my` and `our` for global variables, in my experience they don't come into play in most scripts unless they're run under something which turns all your subroutines into inner subroutine, like `mod_perl`. That's why I suggested using `our` for global variables, since it works the same in both scenarios. My understanding is the `our` was a right and proper way to declare package globals. Are there problems you're aware of with using `our` for package globals under `mod_perl` or anywhere else? -- sgifford's Web page	[reply] [d/l] [select]
