question regarding type hinting parameters of php functions (array_slice)

Hi, i have tried a current snapshot of PHP 5.3 and have a question regarding type hinting. For example when using the function "array_slice(array $array, int $offset, int $length)" with a non-integer length parameter, what is the desired behavior? When calling "array_slice($array, 0, (float)2);" the resulting array is EMPTY. When using the right type "array_slice($array, 0, (int)2);" it works as expected. Shouldn't there be a notice/warning than just a wrong return value? In my case there is neither a warning nor does it work as expected. (perhaps i do something wrong?) Of course i can use int's, but in my opinion either a warning should be given or the function should gracefully handle the wrong typed parameter. Is this problem specific to "array_splice" or the same with other functions? It works with 5.2.x without a problem. Thank you for any feedback, Dirk PS: i posted this to php-general before and someone supposed to better post it to the iternals list
