Difference in split funciton parameters

[lonelyplanet999]

Hi,

I'm a newbie of perl language and I would like to ask the differences
in below pieces of code:

1.
read(STDIN, $stuff, $ENV{'CONTENT_LENGTH'});
@pairs = split(/\&/, $stuff);

2.
read(STDIN, $stuff, $ENV{'CONTENT_LENGTH'});
@pairs = split(/&/, $stuff);

Do they both get a blob of data with length specified by the
CONTENT_LENGTH environment variable then split the name=value pairs
separated by '&' characters ?

Tks!

Yes.

You know that there is a standard module that can be used for parsing
form data, right?

use CGI;
