Not a bug... PHP indeed tries to convert 'foobar' to a number, and because that is not
really possible, it becomes 0. That's why there is that third parameter too.

On my system, in_array wrongly returns true when searching
for zero in arrays that don't contain zero:
Sample code:
in_array(0, array('foobar'));
-->TRUE
If I add the third parameter, it returns the correct
result:
print in_array(0, array('foobar'), true);
-->FALSE
However, I'm pretty sure that 0 doesn't coerce to 'foobar'
- I don't think PHP is that loosely-typed :)
