note 10243 modified in function.array-merge by danbeck

As rlynch@ignitionstate.com states, array_merge kills all integer keys and generates new ones. I've found, that this only happens with values less than 2^31-1 (signed integer). If you use keys greater than 2^32 php recognizes this a strings and leave the keys unchanged. I've you want to preserve the keys, it is recommended to add a string prefix and remove it after merging with, for example, array_walk(). Maybe, for someone this is great feature to clean up an numeric organized array.
