<p>samesite is passed as a string in an options array in PHP 7.3+. We have a boolean being passed as an eighth parameter on line 30.</p>
<p>We would need to test for PHP version something like <code>if (version_compare(phpversion(), '7.3', '>='))</code> and pass it in the options array</p>
<p><code>setcookie($name, $value, time() + $expiry, $path, $domain, $secure, $httponly, ['samesite'=>$samesite])</code> with $samesite having the potential to be None, Lax, or Strict, default Strict. Preferably use their new syntax and pass the rest of the parameters in the options array as well as it makes it cleaner what variables are being set (but this only works on PHP 7.3+).</p>
