Ooooops!!
String starts with non-numeric char is equivalent to zero.
My examples were completely wrong, sorry...
Needless to say this feature is very very confusing lol

Actually, you had submitted it as feature request, but it sounded
more like a bug report to me.

Okay, that might be possible without RFC, but at least some
discussion on internals@lists.php.net seems appropriate. Feel free
to write to the list.

Sorry, Submitting this as a bug was my mistake. I wished it as a feature request.
I think that having "bool $strict = FALSE" by default is very confusing (should be TRUE).
At least the 2nd rule you gave me here is complex enough for not being the default behaviour in the
case of in_array function, I guess ...
Thank you all for your answers anyway.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php
The manual states[1]:
| If you compare a number with a string or the comparison involves
| numerical strings, then each string is converted to a number and
| the comparison performed numerically.
And[2]:
| The value is given by the initial portion of the string. If the
| string starts with valid numeric data, this will be the value
| used. Otherwise, the value will be 0 (zero).

And at least, the final result resulting of my test is:
// 'string' == 0 -> bool(true)
should that be allright ? :)

Sorry, I was missing your important sentence:
> 'Expected result' should be obtained without using the third parameter of in_array
BTW, I think this behavior seems to be a little odd, too...
Probably you know the related issue; array_unique() was broken at PHP 5.2.9 due to use SORT_REGULAR
by default, which feature is reverted at PHP 5.2.10 to use SORT_STRING.
