The array_walk_recursive() function runs each array element in a user-defined function. The array’s keys and values are parameters in the function. The difference between this function and the array_walk() function is that with this function you can work with deeper arrays (an array inside an array).

| array | Required. Specifying an array |
| myfunction | Required. The name of the user-defined function |
| parameter,… | Optional. Specifies a parameter to the user-defined function. You can assign one parameter to the function, or as many as you like. |
