PHP - 如何合并未指定数量的数组？

Question

Is it possible to merge non-specified number of array elements in PHP?

I received data through JSON string (n elements), then I used them to do n loops - each loop saves the result to a different array cell ($result[1], $result[2], $result[3], ... ,$result[n]). I would like to merge the results into a single array (I have to send single array through JSON). Everything works if I write manually array_merge ($result[1], $result[2], $result[3]), but I never know how many variables I will receive.

Thanks in advance

Try this:

$yourListOfArrays = [$result[1], $result[2], ...];

call_user_func_array('array_merge',$yourListOfArrays);
