Write a PHP program that has a variable that contains a phone number.

Use PHP regular expressions to validate if the phone number is in a specific

format $($e$.$g$.,x-x-.$

Display a message indicating whether the phone number is valid or invalid.

You should copy and paste your script as an answer to this question. DON'T

take screenshots of your script. It must be an editable script.

Take a screenshot of your output web page and paste it as a part of your

answer.

Example:

If the phone number variable has the value $1235-9854-88,$ the program

has to show message that the phone number is invalid.

If the phone number variable has the value $054-936-7890,$ the program

has to show message that the phone number is valid.
