• $random_integer = int(rand(10)) + 1;

  Creates a random number:

  $random_integer = int(rand(10)) + 1;

  Turns it into an integer:

  $random_integer = int(rand(10)) + 1;

  An integer is a whole number, without decimal points, like 1, 2, 3.

  Makes sure the number generated is between 1 and 10, and not 0 and 10:

  $random_integer = int(rand(10)) + 1;

  Then assigns it to the scalar variable $random_integer:

  $random_integer = int(rand(10)) + 1;

• print "<p>Your Acme Auto Lucky Integer from 1 to 10 is $random_integer.</p>\n";

  Prints “Your Acme Auto Lucky Integer from 1 to 10 is 5.”

  Of course, your lucky number may be different than 5, because it’s a random number being generated.
