I hope everyone sees that the previous poster's comments are incorrect, in that the behavior is
not ridiculous but completely as expected.
> in_array('123abc', array(123)) returns true
A string is being compared to an integer, in such a situation PHP assumes an integer context wherein
'123abc' evaluates to the integer 123, thus a match.
> in_array('123abc', array('123')) returns false
A string is being compared to a string and OBVIOUSLY these strings are not equal.
