The array_merge_recursive() function merges one ore 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.
|array1||Required. Specifies an array|
|array2||Optional. Specifies an array|
|array3||Optional. Specifies 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.
