  <?php

    // First, create a function to accept two arguments, perform a calculation
    // using them, and then return a sentence with the result to the browser.
    // The function will calculate the area of a rectangle, with the two
    // arguments being width and height. The sentence to be returned is;

    // "A rectangle of length $l and width $w has an area of $area."

    // Where $l and $w are the arguments and $area is the result.

    // Create function to calculate area
    function area($l, $w) {

      // Calculate the area
      $area = $l * $w;

      // Output the sentence replacing the variables where necessary
      echo "A rectangle of length ".$l." and width ".$w." has an area of ".$area.".<br/>";
    };

    // Call the function with some values as an example
    area(2,3);
    area(4,5);
    area(6,7);
