Answer Posted / vipul dalwala
- a require statement imports the functions and objects
only within their defined packages. The use keyword, on the
other hand, imports the functions and objects so they are
available to the current package as if they had been
defined globally. For example,
require Cwd;
$pwd = Cwd::getcwd();
as opposed to
use Cwd;
$pwd = getcwd();
- use statements are interpreted and executed at the time
the file is parsed, but require statements import modules
at run time, which means you can supply a variable name to
a require statement based on other elements of your program.
