Regarding the note left by nicolas at bougues dot net on 26-Sep-2002 11:53, where he stated
> The following expression

> If you just want to know iff haystack contains needle, without such ambiguity, use is_string
> (strstr ("0", "0")), which will evaluate to TRUE.
Use the === operator instead. Thus,
str ("0", "0") === FALSE
if FALSE as expected.
