note 103693 deleted from function.array-merge by danbrown

Note Submitter: Lev ---- jerry at gii dot co dot jp was spot on when he brought up the fact that NULL will be returned in newer PHP builds if any of the arguments are empty. This caused me a bit of headache to figure out at first because I was expecting to be able to just surpress any warnings with: $merged = @array_merge($a, $b); ... as I was expecting in some situations one of the arrays to be null (dynamically parsing XML here...). To make a long story short; it does seem a bit silly that this is the case. In my opinion, it would make more sense to throw the warning and continue on, instead of completely failing. To prevent this - if you expect one of your arguments could ever be null, just do: $merged = array_merge((array)$a, (array)$b); This will safeguard against any situations in which one array might not be set and will always get an array returned.
