Name
map() - modify a mapping, array, or string via application of a function
Synopsis
mixed map( mixed x, string fun, object ob, mixed extra, ... );
mixed map( mixed x, function f, mixed extra, ... );
Description
The (ob, fun) syntax works as if (: call_other, ob, fun :) had been passed as `f'. Map returns a new structure containing the return values of `f' being applied to each element of `x'. Currently, it can be used on arrays, mappings and strings. In the case of mappings, both the key and the value are passed to the function. In the case of strings, the characters are passed to the function one at a time as ints. `extra' and all the following arguments are passed to the function after the element.
