How to map array elements in PHP?

To create a new array from an existing PHP array, you can use the array_map(functionName, 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 specified array but returns 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 is the name of a user-defined callback function applied to all elements of the array. The second parameter specifies the array to process. In this PHP map array element 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.
