Description:
array_merge_recursive() The function is used to merge one or more arrays into one array.
The difference between this function and the array_merge() function is that it handles the situation where two or more array elements have the same key name. array_merge_recursive() does not perform key name overwriting, but recursively combines multiple values with the same key name into an array.
json_encode() function can JSON encode variables; if successful, a JSON-encoded string will be returned; if failed, false will be returned.
