What is the proper way to check if a string is empty in Perl?

Question

I\'ve just been using this code to check if a string is empty:

if ($str == \"\")
{
  // ...
}

And also the same with the not equals operato

Answer 1

As already mentioned by several people, eq is the right operator here.

If you use warnings; in your script, you'll get warnings about this (and many other useful things); I'd recommend use strict; as well.
