Re: anon at anon dot org, about extract() and null values
Personally I've found use extracting multiple resultsets from db where the latter would overwrite the previous when a variable is not null ( and optionally if its not >0 )
It would be useful if $extract_type was extended on top of these two:
EXTR_OVERWRITE
EXTR_SKIP
with something like this:
EXTR_OVERWRITE_NULL
- If there is a collision, overwrite the existing variable if it is null
EXTR_OVERWRITE_0
- Same thing but == 0 or null
EXTR_SKIP_NULL
- If there is a collision, skip the new variable if the existing is not null
EXTR_SKIP_0
- Same thing but == 0 or null
Those ought to cover a few good cases that aren't covered now.
