4. • What is the purpose of the implicit arrays $_POST and $_GET in
PHP? Consider that a web page displays a form containing two text
boxes (named num1 and num2), where the user enters numeric data.
Write a PHP script which collects this form data, finds the sum,
difference and the product of the two numbers and then displays the
same with suitable messages. Assume that the script is to be
embedded in the web page specified by the action attribute of the
form and that the method used when the form is submitted is GET 7
