从两个已知单词生成随机单词

Question

I can do this with numbers:

<?=number_format(mt_rand(0,1));?>

What I want to do is, instead of 0 or 1, echo the words firstclass or secondclass.

This is because I cannot use numbers as class identifiers in CSS.

Essentially, this is just for displaying random stuff within a list and prepending the class identifier with either firstclass or secondclass.

.firstclass {display:none;}

I am not ace with PHP, so I guess I need to set up an array, and somehow attribute:

0 = firstclass
1 = secondclass

within the array, so that I can get my little test script working.

Any suggestions?

You can use a ternary-style if statement if you only have two possibilities:

<?=(mt_rand(0,1) == 0) ? 'firstclass' : 'secondclass'?>
