IMHO assignment is always more readable than function with magic unobvious effects. I'd rather always have assignments than scratch my head each time reading the code - is this the one that modifies the argument or the one that doesn't? >> Strings are not modified in PHP (IS_STRING zvals can be modified >> but the actual string buffers aren't) so there's no actual "write" >> and thus no copy needed.

We won't need to refcount slices since we won't be able to free a slice. We would have however to refcount the string to know if there's a slice referring to it or we can free it. ]>> We already have it, it's str_split(). > > I know. But that is not "casting".

There's nothing wrong with array_map(str_split()) - on the contrary, it makes it clearer that you're taking a string and splitting it into an array. -- Stanislav Malyshev, Software Architect SugarCRM: http://www.sugarcrm.com/ (408)454-6900 ext. 227 -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
