Its better to use an array to achieve this.

$options = array(
  'Option One',
  'Option Two',
  'Option Three',
  'Option Four'
); 
//Shuffle the array
shuffle($options);

You can access the options like this (The order will be random);

$options[0];
$options[1];
$options[2];
$options[3];

Put variables in an array and then shuffle the array

$answers = array(
        'Answer 1',
        'Answer 2',
        'Answer 3',
        'Answer 4'
    );


shuffle($answers);
print_r($answers);

shuffle($answers);
print_r($answers);

This will output something like:

Array
(
    [0] => Answer 3
    [1] => Answer 1
    [2] => Answer 4
    [3] => Answer 2
)
Array
(
    [0] => Answer 4
    [1] => Answer 2
    [2] => Answer 1
    [3] => Answer 3
)
