I think this is happening because you're comparing apples to oranges.
Your first comparison causes an integer to be compared to a string.
Because the string "string" evaluates to the integer value 0, the
comparison succeeds. The manual recommends the use of the identical
comparison operator (===) instead, or--better yet--the strcmp() function
when comparing two strings.
Cheers,
Marco
