PHP: array_merge_ recursive() function
PHP: Merge two or more arrays recursively
The array_merge_recursive() function is used to merge the elements of one or more arrays together. The elements of one are appended to the end of the previous one.
If the input arrays have matching 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 the input arrays contain numeric keys, the later value will be appended instead of overriding the original value.
Version:

Syntax:
array_merge_recursive(array_name1, array_name2...)
