What is the purpose of a confirmation email tool in PHP?

A confirmation email tool in PHP is used to send a verification email to users after they have signed up for a service or created an account. This helps ensure that the user has provided a valid email address and allows them to confirm their registration. The tool typically generates a unique confirmation link that the user can click on to verify their email address.
