### Zip Operation on Multiple Arrays

Recall that in the syntax of the array_map function, you can pass null as the first argument instead of a callable. In this section, we’ll see how that works with an example.

As we have passed the null value in the first argument, it performs a zip operation on all the arrays that are passed from the second argument onwards. In our case, we’ve passed two arrays, and the array_map function combines them into a single multidimensional array.

### Multiple Arguments

As we discussed earlier, you can pass multiple arrays to array_map. In this section, we’ll see how you can use that with a callback function.

In the above example, the createEmployeeObject callable generates an array of Employee objects.

## Conclusion

In this article, we discussed the basics of the array_map function in PHP. We also went through a couple of real-world examples to demonstrate the power of the array_map function.
