The order of the entries is the only difference, I believe. :-) I think that's desirable however, and having the non-recursive version makes it match array_merge(), etc. As for bloat or something, there's virtually no extra code: only PHP_FUNCTION() and then in the wrapper function it just uses zend_hash_merge() just like the + operator, except with its "overwrite" param set to 1. > > array_replace_recursive() will do the same except that it becomes > > recursive only when both the destination and source entries are > > arrays, otherwise the new source entry still replaces any existing > > one. > > Hmm, generic enough to be included?
