PHP随机变量集

Question

How would I set PHP to randomly chose between these two sets of variables to use:

$key = goop;
$john = heck yeah;

and this

$key = roop;
$john = reck reah;

Thanks ever so much! :)

Answer 1

I'd recommend using an array:

$selection = array(
    array('goop', 'heck yeah'),
    array('roop', 'reck reah')
);

shuffle($selection);

list($key, $john) = array_pop($selection);
