I understand that the integer 0 and FALSE are different and I read the manual so many times my head hurts, heh.
There are a few ways to work around this, probably more than I know. (according to the documentation for strrpos() you could test the return from stripos() for is_bool before using it), or (perhaps, cast the return from stripos() to a boolean, although integer 0 probably casts to false :/, I honestly didn't test this {see >>>}), or (easiest solution...just suck up and use !== FALSE all the time :D )
I'm not understanding what you need to work around. What's wrong with
using !== false?
My point in posting this was threefold,
1) to help others who may not know that stripos() returns an INTEGER 0 when the needle is found at the beginning of haystack, and/or don't realize the implications of that.
The manual page for strpos and any other function that may return 0 or
false clearly make this point.
2) My main point is that !== works, so should ===. If !== knows the difference between integer 0 and boolean FALSE, why doesn't ===?
It does, but it also knows the difference between 1 and true, 2 and
true, 3 and true, etc.
3) to get feedback from the community and deepen my understanding of PHP.
I'm trying ;)
