Definition and Usage
The array_merge_recursive() function merges one or more arrays into one array.
The difference between this function and the array_merge() function is when two or more array elements have the same key. Instead of override the keys, the array_merge_recursive() function makes the value as an array.
Note: If you assign only one array to the array_merge_recursive() function, it will behave exactly the same as the array_merge() function.
