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, ... );
mixed *map_array( mixed *arr, function f, mixed extra, ... );

DESCRIPTION

Returns  an array holding the items of 'arr' mapped through either with
that element as a parameter. A second parameter 'extra' is sent in each
call if given.  Principal function:
