Difference Between `my`, `our`, and `local` Variables in Perl

In Perl, `my`, `our`, and `local` are all used to declare variables, but they have different scopes:

  • my: Variables declared with `my` are lexical variables and are scoped to the block in which they are declared. They are only accessible within that block.
  • our: Variables declared with `our` are package variables and are global within the package. They can be accessed outside of the block they are declared in.
  • local: Variables declared with `local` are also global within the package, but they create a temporary value for the variable within the local scope. Once the local scope is exited, the variable reverts to its original value.

It's important to choose the right type of variable declaration based on the desired scope and accessibility of the variable within your Perl program.
