Suspect: a bug in phparray_merge_recursive

{Code...} should theoretically return: {code...} Actually returns: {code...}. Isn't this a bug? Update: this is not a bug, but it is clear when the number key is not merge in the manual.

$adiff = json_decode('{"28":0,"29":0,"30":0,"31":0,"32":0,"33":0,"34":0,"35":0}',true);$diff = json_decode('{"28":1,"29":1,"30":1,"31":1,"32":1,"33":1,"34":1,"35":1}',true);$adiff = array_merge_recursive($diff,$adiff);var_dump($adiff);

Theoretically, we should return:

array(16) { [28]=> int(1) [29]=> int(1) [20]=> int(1) [31]=> int(1) [32]=> int(1) [33]=> int(1) [34]=> int(1) [35]=> int(1) [36]=> int(0) [37]=> int(0) [38]=> int(0) [39]=> int(0) [40]=> int(0) [41]=> int(0) [42]=> int(0) [43]=> int(0) }

Actual return:

array(16) { [0]=> int(1) [1]=> int(1) [2]=> int(1) [3]=> int(1) [4]=> int(1) [5]=> int(1) [6]=> int(1) [7]=> int(1) [8]=> int(0) [9]=> int(0) [10]=> int(0) [11]=> int(0) [12]=> int(0) [13]=> int(0) [14]=> int(0) [15]=> int(0) }

Isn't this a bug?

This is not a bug, but it is clear when the number key is not merge in the manual.

Update:
This is not a bug, but it is clear when the number key is not merge in the manual.

As mentioned in the manual:

If, however, the arrays have the same numeric key, the later value will not overwrite the original value, but will be appended.

If the two arrays have the same number key name, a new index is created at the end of the array (although the index is reset if not mentioned in the Manual ).

In this case, array_replace_recursive (PHP ≥ 5.3) is recommended ).
