array_merge_recursive
(PHP 4 >= 4.0.1, PHP 5, PHP 7, PHP 8)
array_merge_recursive — Merge one or more arrays recursively
Опис
If the input arrays have the same string keys, then the values for
these keys are merged together into an array, and this is done
recursively, so that if one of the values is an array itself, the
function will merge it with a corresponding entry in another array
too. If, however, the arrays have the same numeric key, the later
value will not overwrite the original value, but will be appended.
Параметри
