map

NAME

map()  - modify an mapping, array, or string via application of a func‐
tion

SYNOPSIS

mapping map( mapping | mixed* | string x,
             string fun,
             object ob,
             mixed extra,
             ... );

mapping map( mapping | mixed* | string x,
             function f,
             mixed extra,
             ... );

DESCRIPTION

If the first argument is a mapping, map() behaves exactly like map_map‐
ping().  If it is an array, map() behaves exactly like map_array().  If
it's argument is a string, map() passes each character (as an  int)  to
the  function,  and replaces the character with the return value if the
return value is a non-zero integer.
