The figure below shows an example of concatenating several arrays in a new array and into an array with existing elements.

Figure: concatArray() Example

If the arrays to be concatenated (here array2 or array3) are empty (not NULL ), no exception occurs.
If an array has NULL elements (e.g. element1, element2, NULL, element4), the NULL elements will be preserved after concatenation.
