map_array(3)

NAME
map_array() - modify an array of elements via application of a function

SYNOPSIS
mixed *map_array(mixed *arr, string fun, object ob, mixed extra);

DESCRIPTION
Returns an array holding the items of `arr' mapped through `ob->fun()'. The function `fun' in `ob' is called for each element in `arr' with that element as parameter. A second parameter `extra' is sent in each call if given. Principal function:

    `foreach (index) arr[index] = ob->fun(arr[index],extra);'

The value returned by `ob->fun(arr[.index.], extra)' replaces the existing element in the array. If `arr' is not an array, then 0 will be returned.
