Answer 1

You can approach this as

 $arr = [
  '<a href=https://www.website.ext/post-1/>words 1</a>',
  '<a href=https://www.website.ext/post-2/>words 2</a>',
  '<a href=https://www.website.ext/post-3/>words 3</a>',
  '<a href=https://www.website.ext/post-4/>words 4</a>',
  '<a href=https://www.website.ext/post-5/>words 5</a>'
];
$res = array_rand($arr,2);
echo $arr[$res[0]];
echo '<br/>';
echo $arr[$res[1]];
