Sorry, I used unset in the same way type casting works, not as in unset() ... Common gotcha: http://php.net/unset#example-4824
Here's how the manual refers to it: http://php.net/type-juggling (int), (integer) - cast to integer (bool), (boolean) - cast to boolean (float), (double), (real) - cast to float (string) - cast to string (array) - cast to array (object) - cast to object (unset) - cast to NULL (PHP 5) I understood what you meant but I'd rather have it be more verbose but more clear as well. I read your idea, as "Cast to int, or accept NULL" I rather use/read that as (int unset) rather than (int?) > > BTW: Order would equal what is type casted OR simply accepted! > > Do you have any examples where this could be useful? The same example you gave of data that comes from a database NULL would be retained, else it's type casted to int. // Cast to int, accept null (int unset) 13 // 13 (int unset) '' // 0 (int unset) 0 // 0 (int unset) NULL // NULL (int unset) '342.3Test' // 342 My view is, if you use the naming as it's currently used in type casting, you also get additional functionality: // Cast to string, accept bool (string bool) 'test' // 'test' (string bool) 123 // '123' (string bool) TRUE // TRUE (string bool) FALSE // FALSE (string bool) NULL // '' // Cast to string, accept array (string array) 'test' // 'test' (string array) 123 // '123' (string array) TRUE // '1' (string array) array(1, 2, 3) // array(3) { [0]=> int(1) [1]=> int(2) [2]=> int(3) } I find this way more useful/complete/readable than what you proposed.
