Difference between "my", "our", and "local" variables in Perl

In Perl, "my", "our", and "local" are used to declare variables with different scoping rules:

"my" variables:

• Declared with "my" are lexically scoped and private to the block in which they are declared.
• Use "my" for variables that are local to the enclosing block or subroutine.

"our" variables:

• Declared with "our" are package scoped and can be accessed from any other package within the same file.
• Use "our" for variables that are shared across multiple packages or modules.

"local" variables:

• Declared with "local" are global in scope but temporary in nature.
• Use "local" when you want to temporarily change the value of a global variable within a specific block of code.

Choose the appropriate variable declaration based on the scope and visibility requirements of your variables.
