To create a new array from an existing PHP array, you can use the array_map($callback, $array1, $array2, ...) function. The array_map() function iterates over all the elements of an array and returns a new array containing the results of applying the given $callback function to the array elements. The array_map() function does not change the original array but creates a new one. You can pass several arrays to the array_map() function. The number of parameters the $callback function takes must match the number of arrays passed to the array_map(). The first parameter can be a string representing the function name, an array containing an object and a method name, or an anonymous function. The second parameter specifies the array to process. In this PHP Array Map example, we use the array_map() function to loop over an array and return a new array, where a callback function has been applied to each element in the array.
